Baolan - Model DeNOx -Selective Non-Catalytic Reduction System (SNCR)

SNCR (Selective Non-Catalytic Reduction) is a selective non-catalytic reduction method. It is an economical and practical NOx removal technology. Its principle is based on NH3, urea [CO (NH2) 2], etc. Before the boiler is atomized or injected into the boiler, it is atomized by the heat in the furnace. Sprayed into the furnace temperature range of 800 ? ~ 1100 ?, the reducing agent quickly thermally decomposed into NH3 and other by-products, and then NHCR and NOx in the flue gas undergo SNCR reaction to generate N2. It can therefore be considered a selective chemical process. The reducing agent has different reaction temperature ranges. This temperature range is called a temperature window, which has a great influence on the denitration efficiency of the method.
