Losses in Steam Boiler Dry Flue Gas Losses (Stack losses) H2 Losses Moisture in Fuel Moisture in Air CO Losses Surface Losses – Due to Poor Insulation Fly Ash Losses – Heat Carried by Fly Ash Bottom Losses (Unburnt Losses) OTHER LOSSES Losses due to poor Smoke side Boiler sealing. Losses due to Steam leakages. Blow-down loss. Losses due to the part load operation.

Air Pre Heaters   Air pre heaters                 Air preheaters are provided in boilers to preheat the combustion air. Types           There are two main types: Tubular or recuperative air  pre heaters Regenerative air pre  heaters  Tubular or recuperative air pre-heaters are provided in boilers of a medium and small range of steam generation . This type of air pre-heater becomes very large in size if they have to be used in very high capacity boilers like 600 TPH of steam production and above.  Regenerative air per-heaters are compact and can have a stationary or rotating hood. A combination of a tubular and regenerative type of air pre-heaters is used in very high capacity boilers . " The tubular being used for primary air heating and the regenerative used for the secondary air heating ." In case the boiler designers do not want to go for a combination of tubula...

What is Heat Ex-changer? Heat Ex-changer  works on the principle of  Fluid Dynamics .  Heat Ex-changer  is a device which is used to exchange the heat from one medium of fluid to other medium of fluid. It is widely used in heavy machinery like  Hot Water Generator , Air Conditioner, Adiabatic Coolers, Piston Pumps, Roll Oil Coolers, and Coil Condensers etc.                                 Heat Ex-Changer In this figure, there is coil in the medium and water is flowing through medium. In the coil, the hot water steam is moving, so there will be heat transfer from pipe to water, the water which is coming out, it would be hot and steam which is coming out, it would be cold. Types of Heat Ex-changer: 1.Shell & Tube Heat Ex-changer Shell & Tube Heat  is most common  heat ex-changer  which is used in the  industry . It consist of bunch of tu...
