Everything About Boilers

An Introduction To Boiler

• Its big Vessel that heats water to convert it into steam.

• At atmospheric pressure water’s volume increases 1,600 times.

• That steam is used in many places.

Overview of Boiler Room

• Fire Tube Boiler

• Packaged Boiler

• Water Tube Boiler

• Fluidized Bed Boiler

• Stoker Fired Boiler

• Pulverized Fuel Boiler

Types Of Boiler

Fire Tube Boiler

• Comparatively small steam capacities (12,000 kg/hour).

• Low to medium steam pressures.

• It is operated by oil, gas or solid fuels.

Water Tube Boiler• Used in high steam

demand and pressure.

• Capacity Range - 4,500 – 120,000 kg/hour

• Lower tolerance in water quality

Packaged Boiler • It comes in complete package.

• Main Features• High heat transfer• Good combustion

efficiency• High thermal

efficiency• Faster evaporation • Good convective

heat transfer

• Classified based on number of passes

FCB

• Sand is suspended in high velocity air stream

• Combustion temperature 840° – 950° C

• Capacity - 0,5 T/hr to 100 T/hr

• Fuels: coal, washer rejects, rice husk, biogases and agricultural wastes

Stoke Fired Boilers

a) Spreader stokers

• Coal is first burnt in suspension.

• Flexible.

• Widely Used Boiler.

Stoke Fired Boilers

b)Traveling Grate Stoker

• Coal is burnt on moving steel grate

• Coal gate controls coal feeding ratio

Pulverized Fuel Boiler

• Combustion temperature - 1300 -1700 °C

• Benefits: Quick response to load changes and high pre-heat air temperatures

Glow Worm Boilers

• Glow worm boilers are highly demanded now a days. Every industry is asking for this boiler.
