Firetube Boilers

Model CB Boilers Air atomizing oil burner available for proper oil atomization, maximum combustion efciency, and low maintenance requirements. Air atomizing compressor provided with the boiler package for clean oil burning and ease of maintenance. Combination gas/oil burners provide quick fuel changeover without re-adjustment of the burner. Fuel oil controller eliminates the need for over 40 connections, combining gauges, valves, and regulators into a single casting. Retractable oil nozzle provides easy access and cleaning and eliminates coking of oil and nozzle tip when ring gas. Low NOx Capability Available:

FEATURES AND BENEFITSIn addition to the features provided on all Cleaver-Brooks Firetube Boilers, the following features apply specically to Model CB Firetube Boilers. The CB four-pass dryback boiler is the premium retube boiler design available. Four-Pass Dryback Design: Four-pass design provides high ue gas velocities and low stack temperature for guaranteed maximum efciency. Dryback design provides full access to boiler tubes, tube sheet, and furnace for ease of maintenance. Dryback design includes single rear tube sheet construction, providing reduced tube sheet stresses. Five Square Feet of Heating Surface per Boiler hp: Maximum heat transfer with minimum thermal stresses provide guaranteed efciency and long boiler life. Highest guaranteed fuel-to-steam efciencies. Low Furnace Location Furnace located well below water level with generous clearance from bottom of boiler, allowing proper circulation. Low furnace provides additional safety margin between furnace and water level. Reduces water carryover, producing drier steam. Hinged or Davited Front and Rear Doors: Provides full access to front and rear tube sheet and furnace. Reduces maintenance costs. High Turndown Burner: 4:1 turndown (gas and oil) is standard on boilers up to 250 hp. Guaranteed 10:1 turndown (gas red) 8:1 (No. 2 oil red) standard on 250 hp through 800 hp. Advanced burner design provides maximum combustion efciencies and high turndown. Reduced boiler cycling and maintenance. Boiler stays on line during low load conditions for optimum efciency and performance. Gas, No. 2 Oil, No. 6 Oil, and Combination Gas and Oil Burners Available: High radiant multi-port gas burner designed for high gas velocities and complete fuel/air mixing, providing maximum combustion efciencies.

20 ppm NOx guarantee available on Model CB (LE) Boilers.

Firetube Boilers

Model CB Boilers4. Any efciency verication testing will be based on the stack loss method. When specifying the efciencies in the tables, be sure to include the specic guarantee conditions to maximize the effectiveness of your efciency specication. If you have any questions regarding the efciency specications, please contact your local Cleaver-Brooks authorized representative. For efciencies and stack temperatures at operating pressures not listed, follow these procedures: When the operating steam pressure is between 10 psig and 125 psig, interpolate the values from the efciency tables. When the operating steam pressure is above 125 psig, estimated efciency can be calculated as follows: Example: Boiler: 350 hp. Fuel: natural gas. Operating steam pressure: 200 psig. Find the fuel-to-steam efciency at 100% ring rate. From Table A2-8 for a 350 hp boiler operating at 100% ring rate and an operating steam pressure of 125 psig, the efciency is 82.5%. Using Figure A2-8, note that the stack temperature increases 36 F at the higher operating pressure. To estimate boiler efciency, use this rule of thumb: For every 40 F increase in stack temperature, efciency decreases by 1%. Since the stack temperature rise is 36 F, the decrease in the boiler efciency at 200 psig operating pressure is calculated as follows: 36/40 = .9%. Therefore, the boiler efciency at 200 psig operating pressure is 82.5 - .9 = 81.6%.

PERFORMANCE DATAEfficiencyTables A2-7, A2-8, A2-9, A2-10, A2-11, and A2-12 show predicted fuel-to-steam efciencies (including radiation and convection losses) for Cleaver-Brooks Model CB Firetube boilers. For specic efciencies on retube boiler offerings not listed here, contact your local Cleaver-Brooks authorized representative. Cleaver-Brooks offers an industry leading fuel-to-steam boiler efciency guarantee for Model CB Firetube Boilers. The guarantee is based on the fuel-to-steam efciencies shown in the efciency tables and the following conditions. The efciency percent number is only meaningful if the specic conditions of the efciency calculations are clearly stated in the specication (see Cleaver-Brooks publication CB-7768 for a detailed description of efciency calculations). The boiler manufacturer shall guarantee that, at the time of startup, the boiler will achieve fuel-to-steam efciency (as shown in the tables listed above) at 100% ring rate (add efciency guarantees at 25%, 50%, and 75% of rating, if required). If the boiler(s) fail to achieve the corresponding guaranteed efciency as published, the boiler manufacturer will rebate, to the ultimate boiler owner, ve thousand dollars ($5,000) for every full efciency point (1.0%) that the actual efciency is below the guaranteed level. The specied boiler efciency is based on the following conditions. 1. Fuel specication used to determine boiler efciency: Natural Gas Carbon, % (wt) = 69.98 Hydrogen, % (wt) = 22.31 Sulfur, % (wt) = 0.0 Heating value, Btu/lb = 21,830 No. 2 Oil Carbon, % (wt) = 85.8 Hydrogen, % (wt) = 12.7 Sulfur, % (wt) = 0.2 Heating value, Btu/lb = 19,420 No. 6 Oil Carbon, % (wt) = 86.6 Hydrogen, % (wt) = 10.9 Sulfur, % (wt) = 2.09 Heating value, Btu/lb = 18,830 2. Efciencies are based on ambient air temperature of 80 F, relative humidity of 30%, and 15% excess air in the exhaust ue gas. 3. Efciencies are based on manufacturers published radiation and convection losses. (For Cleaver-Brooks radiation and convection losses, see Boiler Efciency Facts Guide, publication number CB-7767).

EmissionsThe emission data included in this section consists of typical uncontrolled emission levels for Cleaver-Brooks Model CB Firetube Boilers. Cleaver-Brooks Firetube boilers are available with the standard burner package for Model CB, or optional internal ue gas recirculation on Model CB (LE) (refer to Section A3). The Cleaver-Brooks IFGR packages are integrated boiler/ burner/control packages designed specically for CleaverBrooks boilers. For detailed information on Cleaver-Brooks IFGR packages, refer to Model CB (LE) in Section A3.

NOTICEThe data in Table A2-13 represents typical emission levels only. Guaranteed emission levels are available from your local Cleaver-Brooks authorized representative.

Blowdown Water RequirementsSome local codes require blowdown tanks to be constructed in accordance with recommendations of the National Board of Boiler and Pressure Vessel Inspectors. The National Boards recommendations base the size of the blowdown tank on the removal of at least 4 inches of water from the boiler. Table A2-19 lists the approximate quantity of water represented by 4 inches of water at normal operating level for Cleaver-Brooks Model CB Boilers.

Model CB BoilersSound LevelTable A2-20 summarizes predicted sound pressure levels for Model CB Boilers. Tables A2-21 through A2-25 give detailed octave band sound pressure levels for each boiler. These values are based on standard motors. Optional motor types and altitude conditions can increase sound levels. Units The units for the sound level tables are dBA (decibels, measured on the A-weighted scale) in reference to 0.0002 microbars (20 micro-Newtons per square meter). They are standardly referenced in specifying and reporting sound pressure levels on industrial equipment. Test Method The sound pressure levels in the above tables were obtained from tests in accordance with the "ABMA Test Code for the Measurement of Sound from Packages Boilers." In accordance with this code, the sound pressure levels reported were measured on the boiler centerline 4-1/2 feet vertically above the bottom of the base rails and 3 feet horizontally in front of the end of the blower motor or front surface of the electrical cabinet. Sound Level Meter The sound level meter used complies with ANSI S1.4, Type 1 (Precision). The readings are taken with the meter set for slow response.

NOTE: Quantity of water removed from boiler by lowering normal water line 4".

A. The data shown above was taken on the 40 hp. Since the highest Sound Level is below 80 dBA, no additional 36" diameter Firetubes were tested. If Sound Level predictions are required for the 15 thru 30 hp, use the values shown for the 40 hp.
