摘　　要：为实现对某电厂烟气余热利用系统经济性改造的综合评价,提出一种以试验检测为基础结合理论计算的评价方法,将改造对机组的影响统一到对供电煤耗的影响上,并开展了相应的试验检测,该电厂烟气余热利用系统改造在满负荷工况最多可降低供电煤耗3.83 g/(kW·h)。In order to realize the comprehensive economic evaluation of the flue gas waste heat utilization system reconstruction of a power plant,an evaluation method based on the test detection combined with the theoretical derivation calculation is proposed,and the influence of the reconstruction on the unit is unified to the impact on the net coal consumption,and a corresponding test is carried out.The test results show that the reconstruction of flue gas waste heat utilization system of a power plant can reduce the net coal consumption by 3.83 g/(kW·h) at full load.
