Pulverised Fuel - an overview | ScienceDirect Topics

The pulverized fuel is blown into the furnace by a draft of air, which is preheated in a heat exchanger by flue gas exiting the boiler. Initial boiling takes place in the water-cooled wall of the furnace, and the final steam temperature to drive the high-pressure (HP) steam turbine stage is achieved in a superheater.

Challenges when Converting Coal-Fired Boilers to Natural Gas

Riley Power recently participated in field testing on a wall fired boiler rated at 1,779,000 lb/hr of main steam flow. The boiler is an opposed fired design with two (2) levels of burners on both the front and rear walls. The natural gas supply system to the boiler utilized a single flow control valve for all the burners.
