Verification method of ammonia gas mass flow meter for flue gas denitration device and system thereof

The invention belongs to the technical field of selective catalytic reduction (SCR) flue gas denitration of a coal-fired power plant, and particularly relates to a verification method of an ammonia gas mass flow meter for a flue gas denitration device and a system thereof. The invention aims to overcome the problem that the ammonia mass flow meter of a denitration system cannot be verified, and provides the verification method of the ammonia mass flow meter for the flue gas denitration device and the system thereof, so that the ammonia mass flow meter of the flue gas denitration device can be simply and accurately verified, and the verification meets the verification requirement of JJG 1038-2008. The verification method and system provided by the invention are simple, a special verification device is not needed, verification can be carried out by using conventional equipment and instruments of a thermal power plant, the calibration result is reliable, the requirements of JJG 1038-2008 are met, and a guarantee
