coal powder fired burner for connecting boiler form

The problem many experts see with coal-fired power plants is the byproducts they produce in the process of energy generation. In a coal-fired thermal power plant, the burning coal produces carbon dioxide, sulfur dioxide, and nitrogen oxides, as well as other derivatives called bottom ash (made of coarse coal fragments) and fly ash (which is very light and tries to exit the boiler with the gases).

coal combustion Boiler optimization increases fuel flexibility

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.
