How to Run a Coal Fired Boiler at the Best Efficiency .
Boiler efficiency is mainly depended on the amount of losses in the system. In high capacity pulverized coal fired boilers the total losses account to about 12 to 14%. Roughly 50% of the losses are governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The other 50% losses are carbon loss and dry gas loss.Get a Quote

Factors Affecting Combustion Efficiency of CFB Boiler-Zozen .
The circulating fluidized bed boiler is famous for its high efficiency. The boiler efficiency and the boiler thermal efficiency we often say are actually the combustion efficiency of the boiler. It is the ratio of the heat gained by the steam in the furnace in a certain period of time to the total heat generated by the fuel consumed in this period.Get a Quote
