How Does a Coal Power Plant Work?

As an example consider these facts for typical coal fired power plant of capacity 500 MW. Around 2 million tons of coal will be required each year to produce the continuous power. Coal combustion in the boiler requires air. Around 1.6 million cubic meter of air in an hour is delivered by air fans into the furnace.

Boilers - Principles, Applications & Acceptance Testing

Course Introduction. The objectives of a boiler are: To release the energy in the fuel as efficiently as possible. To transfer the released energy to the water, and to generate steam as efficiently as possible. To separate the steam from the water ready for export to the plant, where the energy can be transferred to the process as efficiently as possible.

Paper of the Year A Case Study on Coal to Natural Gas Fuel

Since natural gas has only trace amounts of ash, slagging and fouling would not occur. This lack of slagging and fouling may have a hidden risk of leading to more heat transfer problems in the boiler; coal-fired boilers are designed with a default assumption of a certain amount of slag and reflective ash coating their surfaces.

Boiler Sizing - Heating Help

Jul 16, 2009· When steam heating was new, back at the turn of the 19th century, coal was the fuel of choice. It burned hot, and it burned long. A good coal-fired boiler would stay lit for eight to 10 hours on a load of coal. Those early boilers contained cast iron grates that were similar to what you have in your barbeque, but much thicker and far sturdier.

Slagging and fouling in pulverized-coal-fired utility

A portion of the survey identified boiler design features that are influenced by coal properties. Survey results were used to identify (1) the boiler features that manufacturers consider important when designing to avoid slagging and fouling, and (2) the coal parameters that are used in determining values for the critical boiler design features.
