Coal Based Fuel Feeding System for Boiler - Inst Tools
2021-9-25 The coal is first crushed into minute particles using equipment called pulverizes. The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for ...

How to Run a Coal Fired Boiler at the Best Efficiency ...
2009-7-5 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.
