Abstract
The coal consumption of coal-fired generating units is an important index to measure the level of energy conservation and consumption reduction. This paper proposes a new calculation method of coal consumption for power generation based on steam parameters. This method is based on the parameters of the superheated steam output by the boiler and the reheated steam of the engine. It can accurately calculate the coal consumption for power generation without sampling and testing the calorific value of coal. Taking a 330MW coal-fired unit of a power plant as an example, the operation data of the unit under two working conditions are extracted. The example calculation shows that the calculation method proposed in this paper is close to the coal consumption results of power generation obtained by coal quality test, which can meet the needs of engineering practice. At the same time, it provides a reference basis for soft measurement of calorific value of incoming coal and on-line monitoring of economic indicators.
