A survey-based SCR precision ammonia injection measurement and control system and method

Abstract

This invention discloses a survey-based SCR precision ammonia injection measurement and control system and method, comprising multiple probes; one probe is installed directly below each SCR ammonia injection area, with one probe serving as a standard probe, its end connected to a first CEMS analysis cabinet, and the remaining probes serving as survey probes, all of which are connected to a second CEMS analysis cabinet. This effectively improves upon the serious lag and poor representativeness issues of current survey-based NOx measurement technologies.
