Problems solved by technology

[0002] Due to the particularity of the flue gas after waste incineration, the flue gas purification process at the outlet of the waste heat boiler requires the exhaust gas temperature of the boiler to be around 200°C. The requirements of the flue gas purification process also caused serious corrosion of the low-temperature economizer

Description

technical field [0001] The invention relates to a device for controlling the exhaust gas temperature of a garbage incineration waste heat boiler, and belongs to the technical field of controlling the exhaust gas temperature of a garbage incineration waste heat boiler. Background technique [0002] Due to the particularity of the flue gas after waste incineration, the flue gas purification process at the outlet of the waste heat boiler requires the exhaust gas temperature of the boiler to be around 200°C. The requirements of the flue gas purification process also caused severe corrosion of the low-temperature economizer. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems in the prior art, and further provide a device for controlling the exhaust gas temperature of a waste heat recovery boiler. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A device fo...
