How much coal does a large 660mw boiler burn in one hour?

The amount of coal burned by a large 660 MW boiler in one hour would depend on several factors such as the calorific value of the coal, the efficiency of the boiler, and the load at which the boiler is operating. However, as a rough estimate, a 660 MW boiler operating at full load and with an efficiency of around 38% would burn approximately 250 metric tons of coal per hour.

It's important to note that coal consumption can vary widely depending on various factors, such as the quality of the coal, the boiler's design, and the operating conditions. Therefore, the actual amount of coal burned by a 660 MW boiler in one hour may differ from this estimate.

Coal consumption in a large 660 MW boiler can vary depending on a variety of factors such as:

Calorific value of coal: The calorific value of coal, which is the energy content of the coal, plays a significant role in determining the amount of coal required to produce a given amount of power. Coal with a higher calorific value will require less coal to be burned to produce the same amount of power compared to coal with a lower calorific value.

Boiler efficiency: The efficiency of the boiler is a measure of how much energy from the fuel (in this case, coal) is converted into useful work (electricity). A more efficient boiler will require less coal to be burned to produce the same amount of power.

Load on the boiler: The amount of coal burned by the boiler will also depend on the load at which the boiler is operating. A boiler operating at full load will burn more coal than a boiler operating at partial load.

Boiler design: The design of the boiler, such as the type of furnace and the arrangement of the heating surfaces, can also affect the amount of coal burned per hour.

Taking into account these factors, a typical large 660 MW coal-fired boiler operating at full load and with an efficiency of around 38% could burn approximately 250 metric tons of coal per hour. However, actual coal consumption could vary depending on the specific conditions of the boiler and the quality of the coal being burned.
