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).

How a coal fired power plant work: 1. Heat is created Before the coal is burned, it is pulverized to the fineness of talcum powder. It is then mixed with hot air and blown into the firebox of the boiler. Burning in suspension, the coal/air mixture provides the most complete combustion and maximum heat possible. 2. Water turns to steam
Since occasional drops of water are how the boiler relieves excess pressure, a large amount of water coming out could mean the outlet pipe is working overtime and dripping more frequently. If you find water directly below the boiler on a daily basis, this may suggest that you need to reduce the pressure inside the tank.
As mentioned in section 2.3, temperature of steam inside water pipes and thickness of ash deposited on the water pipes are assumed to be the same as the coal-fired case. With arbitrary amount of heat absorption, gas temperature in the case of NH 3 co-firing in each zone is calculated by numerical simulation.
several boiler parameters responsible for the unit and steam temperature derates, which include boiler/burner technology and furnace he at input/plan area ratio. Boiler natural gas feasibility studies are required to determine the effects of burning natural gas in a coal -fired boiler.
These boilers are water tube type except in combination boilers where the boiler bank is fire tube and the rest water tube. Grate Solid fuels like Coal or Bio-mass is fed into furnace with the help of mechanical or pneumatic fuel feeders and spreaders.
NEVER light a fire under a boiler without a double check on the water level. Many boilers have been ruined and many jobs lost this way. ALWAYS have at least one gauge of water before lighting off. The level should be checked with the gauge cocks. You will not be fired for being too careful. NEVER light a fire under a boiler without checking all
