Document Type and Number:
WIPO Patent Application WO/2021/174785
Kind Code:
A1
Abstract:
A method for monitoring the effect of ammonia escape from denitration on a downstream rotary air preheater. Hot air having a temperature of 250ºC or above is blown into a heat storage element of an air preheater from a cold end of the air preheater, the blown-in hot air is extracted at a position, opposite to the hot air blow-in position, of a hot end of the air preheater, and the ammonia concentration is measured. The method can be used for evaluating the control level of ammonia escape from a denitration device and the effect of ammonia escape on ash clogging in a downstream rotary air preheater, and the method is simple and practical and can replace conventional complex ammonia escape measurement methods.
