coal crushed efficiency

How to Calculate the Coal Quantity Used in a Power Plant

Efficiency. Energy conversion takes place in two stages. The first part of the conversion is efficiency of the boiler and combustion. For this example we take 88 on an HHV basis that is the normal range for a well-optimized power plant. Second part is the steam cycle efficiency. Modern Rankine cycle adopted in coal fired power plants have

Pulverized coal-fired boilerWikipedia

The raw coal is then fed into the pulverizer along with air heated to about 650°F / 340°C from the boiler. As the coal gets crushed by the rolling action the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
