Abstract
This paper systematically analyzes the problems that occur during the operation of the waste incinerator and waste heat boiler in a certain waste incineration power plant,and then proposes a capacity improvement renovation plan.Overall,the air-cooled wall structure is changed to a water-cooled combustion chamber structure;the structure of the front and rear arches is improved,with water-cooled walls arranged in the rear arches and fire-resistant casting materials applied externally;a vertically arranged screen type water-cooled wall is added below the second flue gas preheater,and a steam blowing point is added at this location;the original shock wave blowing scheme for the heating surface of the waste heat boiler is changed to a combined blowing method of steam blowing and shock wave blowing.After the renovation,the incinerator operates stably,and the waste treatment capacity increases from 500 t/d to 596 t/d;the inlet temperature of the high-temperature superheater has decreased from 620℃to 552℃;the evaporation rate increases by 23.9%compared to the design value;the monthly power generation has increased from 5.985 6 million kW·h to 7.174 7 million kW·h.The renovation ideas of this project can provide reference for the capacity improvement renovation of other waste incineration power plants.关键词
