How to Run a Coal Fired Boiler at the Best Efficiency
Dry gas loss is due to the heat carried away by the flue gases leaving the boiler. Today many of the boiler designers reduce this loss by recovering the heat after low temperature superheater by larger economizer and air pre-heaters. As designers go for lower and lower exit gas temperature the size of
