| Zusammenfassung: | The invention discloses a thermal power plant flue gas microwave heating dissociation denitration method which comprises the following steps: boiler flue gas generated by thermal power plant denitration firstly enters a selective catalytic reduction denitration system for denitration, and the denitrated gas enters a microwave reaction cavity for microwave nitrogen oxide removal; wherein the temperature in the microwave reaction cavity is 550-650 DEG C, the microwave frequency of the microwave reaction cavity is 2550 +/-15 MHz, and the microwave output mode of the microwave reaction cavity adopts continuous waves; by selecting microwaves with the frequency of 2550 +/-15 MHz and matching with the temperature in the microwave reaction cavity 3 with the temperature of 550-650 DEG C, higher energy can be provided to complete denitration, the efficiency is higher, additional auxiliary measures do not need to be used, and the denitration cost is greatly reduced.
