Pulverised Coal Combustion - an overview ScienceDirect ...

Pulverized coal (PC) combustion is presently the system of choice for coal-fired power-generating plants. In PC combustion, the coal is dried and is ground to a specified fineness, with a maximum particle size of 250–300 μm, depending on the reactivity of the coal. Coal preparation, which involves feeding, drying, and grinding of the coal, and the pneumatic transport of the pulverized coal to the

Life Cycle Assessment for supercritical pulverized coal ...

20-07-2017  The main advantages of pulverized coal combustion are: high reliability, full automation, adaptation to a wide range of coal ranks and operating requirements, excellent capacity for increasing unit size, and cost-effective power generation. High energy consumption and high SO2 and NO x emissions are some disadvantages of this technology (Toporov, 2014). Depending on the maximum pressure reached in the boiler, the power plants are distinguished as subcritical plants or supercritical plants.

The pulverized coal is blown with part of the combustion air into boiler plant through a series of burner nozzles. Combustion takes place at temperature from 1300 – 1700 °C, depending largely on coal grade. The flue gas formed in the furnace passes over the superheater, economizer, air-preheater, ESP and finally is evacuated by the induced draft fan into the chimney.

Coal dust - Wikipedia

Pulverised coal is a significant dust explosion hazard, as large quantities are suspended in air for transfer from the mill to the power plant. Explosions have occurred when the flow drops and flames in the burning chamber pass back along the ductwork delivering fuel. See also.
