Coal-Fired Boiler - an overview ScienceDirect Topics

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.

Firetube boilers - sales, installation and service

Firetube Boiler Design & Operation Firetube boilers operate by sending combustionflue gas through a series of straight tubes surrounded by hot water stored in the same vessel. Often identified by the number of passes used (such as a 3-pass or 4-pass firetube boiler), this refers to the number of times combustion gas flows the length of the pressure vessel as it transfers heat to the water.
