The invention discloses a general performance test method for a boiler flue gas waste heat utilization system, which comprises the following steps of: testing thermal performance of a steam turbine and then performing correction calculation to obtain the energy saving amount of the flue gas waste heat utilization system, and testing the shutdown working condition of the flue gas waste heat utilization system to obtain parameters such as unit heat consumption rate, boiler efficiency and coal consumption rate. When the flue gas waste heat utilization system is put into operation, it is judged that the boiler efficiency of the system does not change, and when the boiler efficiency changes, the boiler efficiency and the output heat of the boiler are corrected according to the arrangement mode of the flue gas waste heat utilization system. And calculating the heat consumption rate and the coal consumption rate of the steam turbine by utilizing the corrected boiler efficiency and boiler output heat, and finally comparing the coal consumption rate of the flue gas waste heat utilization system to obtain the energy saving amount of the flue gas waste heat utilization system. According to the invention, the energy saving amount of different flue gas waste heat utilization systems can be determined through the performance test of the steam turbine and the flue gas waste heat utilization system and the performance test of one boiler.
Description
technical field [0001] The invention relates to a general performance test method of a boiler flue gas waste heat utilization system, in particular to a correction calculation method of energy saving after a flue gas waste heat deep utilization system is installed in the tail flue of a coal-fired boiler, and belongs to the field of coal-fired power generation. Background technique [0002] At present, the boiler flue gas waste heat utilization system is one of the necessary systems for power plants. Most power plants in the country have installed boiler flue gas waste heat utilization systems through new projects or renovation projects. With the advancement of technology, the flue gas waste heat utilization system has developed from the low-pressure / low-temperature economizer system at the beginning to the series system and the parallel system. There is no unified name for the series / parallel system at present, and the present invention is only based on the layout form. clas...
