To solve the problem of poor accuracy of measurement in standard coal consumption rate and great fluctuation of data using positive balance method for electricity generation and supplying in domestic coal-fired power plants

a novel measurement method of standard coal consumption rate is proposed. By using this method

the standard coal consumption flow can be calculated more accurately according to the combustion air and flue gas flow in the boiler under the condition of lack of calorific value of coal and possessing low requirement of coal sample representative. The actual calculation and verification test result show that

the difference between the standard coal consumption rate for electricity supply and coal consumption rate obtained by the actual measurement is very small and the maximum deviation is 2.06 percentage points. This method can be applied to not only the calculation of standard coal consumption in coal-fired power plants and soft measurement of calorific value of charging coal

but also the real-time on-line monitoring of energy consumption of plant unit. There is a positive influence on cost accounting

energy-saving management

coal-blending and operation optimization in coal-fired power plants.
