Imperial 4441 Natural Gas Performance Data(Performance for 27.7"w.c main air pressure operating at stoichiometric ratio unless stated otherwise)

— Combustion Air: 0.3-41.6"w.c. (0.08-10.3 kPa) air pressure, max 350°F (177°C).

— Fuel: Natural gas with propane gas versions available in the -1 thru -4-B sizes. Gas pressure varies per size with 19"w.c. (4.7 kPa) is maximum required at design capacity, for 27.7"w.c. (6.9 KPA) combustion air pressure, stoich ratio.

— Flame Supervision: Flame rod or UV detector Consult National Safety Standards and insurance underwriters for specifi c fl ame supervision requirements. Flame supervisory components must be ordered separately. See Section 7.1 for correct fl ame rod part number.

— Ignition: Direct spark (no pilot) with 6000 V transformer. A halfwave transformer prevents UV sensing of the spark during trial for ignition. Lighting not recommended above 27.7"w.c. (6.9 kPa) main air pressure. Excess air required for ignition.

— Control: Excellent performance with all control systems; StepFire™, on-ratio and thermal turndown. A limiting orifi ce valve must be installed in gas supply line within 1 ft . (30 cm) of burner. A ratio regulator should be within 4 ft . (122 cm) of burner.

— Relight: Tempest® burners require spark for re-ignition. They will not relight from a hot tile or furnace.

— Piping: For cross-connected systems, maximum gas pressure at the burner can be adversely impacted by excessive pressure drop in the gas line between the ratio regulator and the burner. The design, selection, and installation of these systems must take into account the gas pressure required at the burner to achieve the desired heat release (i.e. gas fl ow). For more detailed information on cross-connected control systems, see section 4.1.

SAFETY

I. Hazard Recognition

Fives has provided a combustion system to be used for this heating process. By taking proper precautions and following recommended procedures, the Combustion System can be operated with limited risk. However, all individuals who use or service this system must recognize that hazards do exist.

These hazards include but are not limited to:

— Flammable fuel mixtures can explode — Combustion products can kill — Electric shock can kill — Pressurized fuels can rupture pipes and hoses — Moving parts can pinch — Adjustments can cause fl ammable mixtures

Precautions and procedures to avoid these hazards are described herein. Failure to follow the precautions and procedures may result in harm to both personnel and property. Protect yourself and others by heeding these warnings.

II. Basic Safety Guidelines

The following safety guidelines apply to the combustion system at all times:

It is imperative that all National, State, and Local Codes and Regulations pertaining to the installation of this equipment be adhered to. Installation should be done by qualifi ed personnel. Failure to do so may result in personal injury and/or property damage.

Insurance carrier should review and approve the combustion system design and the associated operating procedures.

No open fl ames, smoking, or sources of ignition are permitted near the combustion system to guard against fi res caused by fuel leaks.

A Hazardous Work Permit (or equivalent) is required before servicing the equipment because of the need for coordination of actions of operations and maintenance personnel, and because of the potential hazards topersonnel and equipment.

Lock out the pressure supply source of fuels and de-pressurize all piping, tubing and pressurized vessels before maintenance or repair to avoid the hazards of a release of pressure, such as striking objects or fi re.Follow established Lock Out / Tag Out procedures.

Use special caution when working in confi ned spaces to prevent asphyxiation. Follow established Confi ned Space Entry procedures.

De-energize and Lock Out electrical circuits before attempting any repair or maintenance of electrical equipment to prevent electrical shock. Follow established Lock Out / Tag Out procedures.

Check all safety devices periodically to ensure continued reliability. NFPA 86 (EN746-2 in Europe) requires safety devices to be tested at least annually.

NFPA 86 requires Safety Shutoff Valves to be replaced before they exceed their maximum rated cycles. If the number of cycles are estimated, replace Safety Shutoff Valves before they reach 90 percent of the lifetime open-closed cycles.



Never operate the system without all safety devices intact and operating properly.

Never operate the system if the fuel is leaking.

Make no substitutions for the prescribed procedure or material when repairing the system.


Equipment must only be used for the purpose for which it was designed. Any unauthorized use or application must be avoided in order to prevent accidents. Always operate and maintain this equipment in accordance with the manufacturers' and plant operating instructions. At the fi rst indication of any trouble or malfunction, investigate and shut down the equipment if necessary to determine the cause or for safety reasons. Do not operate until trouble has been corrected.

III. Hazardous Work Permit

The purpose of a Hazardous Work Permit is to ensure that work known to be hazardous or work that could cause a hazardous condition is properly planned and controlled, so that it can be accomplished with reduced risk.

Servicing the Combustion System involves situations that are not normally encountered in standard operations. Proper procedures, planning, and a pre-job discussion between worker and supervisor are necessary to reduce risk to personnel. Hazards must be anticipated. During a pre-job discussion, the worker and the supervisor must recognize hazards and plan means to avoid them.

The following types of work on the combustion system should be covered by the Hazardous Work Permit or equivalent:

— Pressure testing — Any work or entry into areas where oxygen defi ciency might reasonably be encountered. — All electrical repair work and troubleshooting. — Any work on equipment or piping where pressure may still exist or be trapped. — Any site specifi c job that the plant supervision has designated to require a Hazardous Work Permit.

Leak test equipment with approved medium only. Leak test pressure must not exceed the specifi ed system operating pressure. Incorrect medium or excessive pressure may damage the equipment or components.

Make no substitutions for the prescribed procedure or material when repairing the equipment.

IV. Flammable Gas Mixtures Can Explode

Explosion and improper combustion are major hazards of any combustion system for process furnaces. To minimize your exposure to this hazard be sure to:

— Follow the recommended procedures for operating and servicing the fuel systems. — Keep all personnel away from furnace areas during startup. The greatest potential danger of an explosion exits during a cold light-off when fuel can accumulate in the furnace, and when the furnace temperature is below the auto-ignition temperature of fuel being used. When the furnace temperature is above 1400F, there is less danger of an explosion because fuel and air oxidize upon mixing.



— Check all safety devices periodically to ensure correct operation. — Never operate the system without all safety devices intact and operating properly. — Never operate the system if the fuel is leaking. — In case of a fuel leak, stop the combustion system immediately. — Before attempting to repair any leak that involves more than the in-situ tightening of fi ttings, fl anges, unions etc. or one where there is any risk of fracture of fuel-carrying components,

ALWAYS: — Disconnect and Lock Out all power sources — Close and Lock Out manual fuel equipment isolation valves — Bleed pressurized fl uids from piping systems — Install isolation blanks in the fuel supply lines — Purge fuel lines with clean, dry, oil-free air — Do not use nitrogen in confi ned spaces — Pressure test the repair before returning the system to service

WARNING


V. Combustion Products May Kill

Any maintenance that is done inside furnaces may be dangerous due to the possible accumulation of fuel and/or combustion prod-ucts, including carbon monoxide, carbon dioxide, hydrogen, and nitrogen oxides.

Mixtures of fuel and air in a confi ned area may explode when brought in contact with a fl ame or other source of ignition.

Carbon monoxide is a toxic, colorless, odorless, and tasteless gas. Even at low concentrations, it can rapidly cause harmful eff ects, including death, without warning.

Carbon dioxide can cause rapid asphyxiation and death in confi ned, poorly ventilated areas.

Hydrogen is a fl ammable gas and an asphyxiant. A mixture of hydrogen with oxygen or air in a confi ned area may explode if ignited by spark or fl ame.

Nitrogen oxides are highly toxic gases and may accelerate combustion.

Before any work is performed inside the furnace, ALWAYS:

— Disconnect and Lock Out all power sources. — Close and Lock Out manual fuel equipment isolation valves — Bleed pressurized fl uids from piping systems — Install isolation blanks in fuel supply lines — Purge fuel lines with clean, dry, oil-free air — Do not use nitrogen in confi ned spaces

— Follow your site confi ned space entry procedures



VI. Electric Shock Can Kill

Follow all NFPA 70E Standard for Electrical Safety in the Workplace requirements when working on electrical equipment (EN 50110:2013 in Europe).

Electricity is present at many diff erent points throughout the system. Improper use of electrical devices or attempting to service equipment without fi rst disconnecting the electric power source can lead to electrical shock or electrocution.

WARNING

Unqualifi ed personnel must not attempt to service or repair electrical equipment. Do not attempt to trouble-shoot or service electrical equipment when it is energized. Some wires remain energized even if all switches are turned off . De-energize and Lock Out all electrical sources before opening enclosures. Close panel door before operating. Do not bypass or disconnect safety interlocks.

Manual fuel valves should be closed when servicing the electrical system.

Any time service is being performed, Lock Out/Tag Out procedures should be observed and/or to prevent someone from starting the system, close and Lock Out the manual fuel valve(s) and electrical disconnect(s).

Electrical hazards also exist within a junction box. More than one disconnect may be required to safely de-energize a system.


VIII. Moving Parts Can Pinch

Pinching hazards exist on the fuel train due to the manual and automatic operation of the actuators. Wear protective equipment, such as safety glasses and protective gloves when tending to this equipment. Keep hands, body, and loose clothing away from moving parts.

VII. Pressurized Fluids Can Rupture Pipes and Hoses

Compression of any fl uid introduces hazards. Similar to a spring, compressed fl uids represents stored energy. Should a break occur, piping or hoses may become a lethal whip. Should a rupture occur, failing equipment may be fragmented and the fragments pro-pelled with great force.

For these reasons, wear protective equipment, such as safety glasses and protective gloves when tending to this equipment. All ves-sels, piping, and equipment that may contain pressurized fl uids must be designed, installed, and tested to strict codes and standards before use to prevent a rupture.

Pressure relief devices should be installed wherever higher than design pressures could be experienced because of negligence, accident or component failure.

WARNING

Piping contains pressurized fl uids. Make sure piping, tubing and pressure vessels are depressurized before repairs are attempted.



IX. Adjustment Can Cause Flammable Mixture

Safety devices have been installed in this system to verify the system performs in the design manner. Operating these devices with settings other than those designed and set by Fives for this process may expose personnel and equipment to serious hazards. Access to devices and settings must be limited to qualifi ed technicians who are trained in combustion systems.

Do not tamper with the controls and safety devices or attempt to alter their program or settings. Tampering with a controller may make the process unsafe. Operating with a controller other than the one which was designed and installed by North American may expose personnel to serious hazards. The controllers must not be changed without prior written consent from North American.

XI. Emergency Shutdown

Familiarize yourself with all normal and emergency shutdown procedures before starting and operating this equipment.

Control panels must be equipped with a large, red MASTER STOP button on the door of the control panel. Pressing this button causes the automatic fuel valves to close, stopping the fl ow of fuel.

The fuel system must also be equipped with manual valves. Close these valves to ensure stopping the fl ow of fuel.

All Data:...............................is based on fi ring with ambient combustion air.

UA-DA:................................Published data is reasonably accurate between 6.9 and 34.6"w.c. (1.7 and 8.6 kPa) main air pressure (UA) if piped with >5 diameters of straight pipe into burner. Square rooting the UA-DA pressure drops using the published 27.7"w.c. (6.9 kPa) data is reasonably accurate between 6.9-34.6"w.c. (1.7-8.6 kPa) air pressure. Below 6.9"w.c. (1.7 kPa) the UA-DA data is suspect and should not be used for accurate air metering. Square rooting will over-estimate air fl ow below 6.9"w.c. (1.7 kPa) and underestimate above 34.6"w.c. (8.6 kPa).

UG-DG:................................UG-DG information can be used to approximate fuel gas fl ow. External gas orifi ces or O2 analysis should be used for precise determination of fuel metering and air/fuel ratio.

Burner Selection


1. System has been sized for standard conditions. For any unusu-al conditions including elevation, high ambients, preheated air, etc., the individual components must be selected based on the maximum actual fl ow rates that will be encountered during operation.

2. System has been sized based on 27.7"w.c. (6.9 kPa) air pressure at the burner at high fi re and 1"wc air pressure at the burner at low fi re. To ensure tight shutoff of the 7216- - BP regulator at low fi re, allow for a –2" bias on the regulator spring. Thus the maximum gas pressure available from the 7216 regulator at high fi re is 25.7"wc (with 27.7"w.c. impulse).

3. To increase the air impulse available to the 7216 (if necessary), a metering orifi ce or other fi xed resistance component can be installed downstream between the 1196 and the air impulse line to the regulator.

4. For the components selected in Table 1, and under the condi-tions specifi ed above, the 4441-1, -2, -3, -5, and -6 will operate with up to 30% XSF. For the 4441-4-A and -4-B, 1"w.c. ofadditional air impulse pressure is required to reach 30% XSF capability. In order to achieve higher XSF on any size, addition-al air pressure is required to impulse the 7216 regulator.

TEMPEST GAS BURNERTILE INSTALLATION INSTRUCTIONS

Ceramic Tile in Fiber Wall Installation Instructions(see Figure 1)

1. Cut circle opening in furnace shell. Allow ¼ " clearance all the way around tile.The hole size in the shell for 4441-1 through -4-B is 5½ " (140) and for 4441-5 through -7 is 8" (203).

2. Cut a straight hole in fi ber wall for the burner tile. The hole should be approximately ½ ” (13) smaller than the tile OD to allow the fi ber to be tight up against the tile.

3. Wrap the tile in cling wrap and then insert tile into the fi ber wall. The cling wrap will assist in pushing the tile into a smaller fi ber hole.

4. Bolt burner to furnace shell. We recommend using a fl anged burner with a gasket at this joint for applications with pressurized chambers. A burner mounting gasket is available from North American. 5. Periodically check for fi ber shrinkage in vicinity of the burner tile. Repack any voids with bulk fi ber insulation to maintain a thermal seal between the furnace interior and the shell.

Ceramic Tile in Monolithic/Brick Wall Installation Instructions (see Figure 2)

1. Cut circle opening in furnace shell. Allow ¼ " clearance all the way around tile.The hole size in the shell for 4441-1 through -4-B is 5½ " (140) and for 4441-5 through -7 is 8" (203).

2. Make hole in furnace wall to insert the tile. We recommend a minimum gap of 1½ " (38) between the tile and the brick/monolithic wall. Fill this gap with compressed ceramic fi ber. The hole in the wall can be either square or round. If pushing the tile through the fi ber, wrap the tile in cling wrap to assist the tile through the fi ber.

3. Bolt burner to furnace shell. We recommend using a fl anged burner with a gasket at this joint for applications with pressurized chambers. A burner mounting gasket is available from North American.

4. Pack fi ber tightly around the tile. Fill all voids to provide a tight thermal seal from the furnace interior to the shell.

5. Periodically check for fi ber shrinkage in vicinity of the burner tile. Repack any voids with bulk fi ber insulation to maintain a thermal seal between the furnace interior and the shell.

Square Block Refractory in Fiber Wall Installation In-structions (see Figure 3)

1. Cut square opening in furnace shell. Allow ¼” (6) clearance all the way around the tile and jacket. 2. Cut a hole for the burner tile and jacket in fi ber wall. The hole should be approximately ½ ” (13) smaller than the jacket to allow the fi ber to be tight up against the jacket.

3. Insert tile with metal jacket into the fi ber wall. We suggest a metal jacket around the tile to support the refractory. Do not use a metal jacket for application higher than 1800°F (982°C). For temperatures above 1800°F (982°C), please see Figure 4 for the recommended tile installation.


Square Block Refractory Tile in Brick or Monolithic Wall Installation Instructions

(see Figure 4)

1. Cut square opening in furnace shell. Allow ¼” (6) clearance all the way around the tile. The hole size in the shell for 4441-1 through -4-B is 8" (203) square hole and for 4441-5 through -7 is 10½ " (267) square hole. 2. Make a hole in the wall. We recommend a minimum gap of 9" (229) between the tile and the monolithich/brick wall for the castable/rammed material.


4. Use a castable or rammed material to support and secure tile. Provide a shelf support angle to support castable or rammed material.

5. Use densely packed ceramic fi ber around castable or rammed material to act as an expansion joint.

6. Waterproofi ng may be required to prevent surrounding refractory from absorbing water from castable refractory. Using a plastic sheet to waterproof is recommended.

This annex is not a part of the requirements of this NFPA document but is included for informational purposes only.

C.1 General. The recommendations in this annex are prepared for the maintenance of equipment. Diff erent types of equipment need special attention. A preventive maintenance program, including adherence to the manufacturer's recommendations, should be established and followed. This program should establish a minimum maintenance schedule that includes inspection and action on the recommendations provided in the following paragraphs. An adequate supply of spare parts should be maintained, and inoperable equipment should be cleaned, repaired, or replaced, as required.

C.2 Visual Operational Checklist.

The following operational checks should be performed:(1) Check burners for ignition and combustion characteristics. (2) Check pilots or igniters, or both, for main burner ignition. (3) Check air-fuel ratios. (4) Check operating temperatures. (5) Check sight drains or gauges, or both, for cooling waterfl ow and water temperature. (6) Check that burners or pilots, or both, have adequate combustion air. (7) Check the operation of ventilating equipment.

C.3 Regular Shift Checklist.

The following operational checks should be performed at the start of every shift :(1) Check the set point of control instrumentation. (2) Check positions of hand valves, manual dampers, secondary air openings, and adjustable bypasses. (3) Check blowers, fans, compressors, and pumps for unusual bearing noise and shaft vibration; if V-belt driven, belt tension and belt fatigue. (4) Perform lubrication in accordance with manufacturer's requirements.

C.4 Periodic Checklist.

The following maintenance checklist should be completed at intervals based on the recommendations of the manufacturer and the requirements of the process: (1) Inspect fl ame-sensing devices for condition, location, and cleanliness. (2) Inspect thermocouples and lead wire for shorts and loose connections. A regular replacement program should be established for all control and safety thermocouples. The eff ective life of thermocouples varies, depending on the environment and temperature, and these factors should be considered in setting up a replacement schedule.
