Coal-Fired Boiler - an overview | ScienceDirect Topics
This process converts coal into either a low-sulfur boiler fuel or into refinery syncrude. Coal is slurried in a recycled oil and reacted with hydrogen at 3000 psi. The mixture is pretreated and pumped into the bottom of an ebullated bed catalytic reactor. The recirculated oil maintains the catalyst in a fluidized state.

Test Your knowledge on Boilers - Chemical Engineering Site
Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.
