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.
coal fired power plant boiler. How Coal Power Plants Produce Electricity. The conversion from coal to electricity takes place in three stages. Stage 1: The first conversion of energy takes place in the boiler. Coal is burnt in the biomass fired boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2: The second stage is the thermodynamic process.
