Boiler - Azar

A water tube boiler consists of combustion chamber with tubes, steam and water headers and drums, super heaters, air heaters, economizer and preservers. In this boilers, integrated fin coated vertical tubes are used since water tubes are under high thermal charge, pressure and temperature stresses effects should be designed precisely.

How to Run a Coal Fired Boiler at the Best Efficien

Primary air to secondary air ratios ; As designers go for lower and lower exit gas temperature the size of air pre-heaters go up. Boiler tuning for optimal Dry gas . Keep an optimal excess air level, generally about 20% in a coal fired boiler which change the heat recovery pattern of economiser & air-pre-heater.

Why Economizer and Air Pre-Heaters are Provided i

A degrease of about 20 % of boiler efficiency is seen by not providing both economizer and air pre-heaters. If economizer alone is provided then the efficiency will be lower by 12 % when compared to that with economizer and air pre-heaters. Both economizer and air pre-heaters are called heat recovery system in a boiler.
