Description

technical field [0001] The invention relates to the technical field of optimal design of a flue gas waste heat recovery system, in particular to an optimal design method of a flue gas waste heat recovery system considering changes in external parameters in all working conditions. Background technique [0002] In recent years, the installed capacity of new energy power generation in my country has grown rapidly, and coal-fired power generation has transitioned from the main energy source to the basic energy source. Coal-fired power generation will undertake more peak-shaving tasks and will operate with frequent variable loads for a long time, which puts forward new requirements for the flexibility of thermal power units. Flue gas waste heat recovery technology is an effective means to improve the efficiency of coal-fired power generation units and reduce the emission of pollutants from power plants. With the increasingly frequent operation of coal-fired units under variable ...
