Abstract
PURPOSE: The controller for injecting NH3 of an amount necessary and sufficient for the reducing reaction under the overall judgement for each fluctuating element, by equipping the flowmeter for the gas to be treated, the concentration meter for NOx in the gas to be treated, etc. at the front stage of the reactor and equipping the concentration meter for NH3, etc. at the rear stage of the reactor.
