### How to Calculate the Coal Quantity Used in a Power Plant

Oct 15, 2009 · 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.Learn More

### Boiler Efficiency - an overview | ScienceDirect Topics

Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses. Table 3.2.Learn More
