Jun 08, 2018 · Coal that has been ground into a fine powder by a pulverizer is blown into a furnace-like device, called a boiler, and burned. The heat produced converts water, which runs through a series of pipes in the boiler, to steam. The high-pressure steam turns the blades of a turbine, which is connected by a shaft to a generator.

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).

Steam can be produced a lot faster and more efficiently using this method. These boilers were fired mechanically using a rolling chain grate driven by either electricity or steam. Coal from hoppers in the roof fell down chutes via gravity onto the slow moving chain. The chain then carried the coal under the water tubes where it heated the water.
