Abstract：In order to promote the application of semi-coke on large-scale pulverized coal fired boiler,the impacts of coal blending with semi-coke on the operational economic of power plant such as the boiler gross efficiency,the station service power consumption rate,the net coal consumption,the environmental protection indicators,maintenance cost,and coal price ctc were systematically analyzed by testing the performance of coal blending on a 135 MW power plant.Results show that coal blending with 30％ semi-coke has little effect on the operational economic,and it demonstrates less than 1％ impact on the power supply cost,while the price of semi-coke is the main factor affecting the widely application of semi-coke on power plant.
