Application of ultra-low NOx emission control for CFB

Selective non-catalytic reduction (SNCR) is a proven, commercially-available technology that has been applied since 1974 with over 300 systems installed worldwide on various combustion sources including coal-fired utility applications (Wu, 2002).In the United States as of Mar. 2015, 31.5 GW or 11% of total generation capacity was equipped with SNCR systems (Patel, 2015).

Mitsubishi Power, Ltd. | Circulating Fluidized Bed (CFB

The circulating fluidized bed (CFB) is a type of Fluidized bed combustion that utilizes a recirculating loop for even greater efficiency of combustion. while achieving lower emission of pollutants.Reports suggest that up to 95% of pollutants can be absorbed before being emitted into the atmosphere. The technology is limited in scale however, due to its extensive use of limestone, and the fact

Selective Non-Catalytic Reduction (SNCR) EES through our STEP Combustion group supplies Selective Non-Catalytic Reduction (SNCR) systems that reduce NOx by up to 40% on conventional boilers and up to 80% or more on fluidized bed boilers (C/BFB). STEP's propriety high efficiency SNCR system utilizes urea or ammonia reagent which is injected into the post combustion flue gas stream to react with the NOx and form N 2 and H 2 O. STEP's Selective Non-Catalytic Reduction systems can use

The NO X OUT ® SNCR Process is a urea-based Selective Non-Catalytic Reduction (SNCR) process for reduction of oxides of nitrogen (NO X) from stationary combustion sources. The process requires precisely engineered injection of stabilized urea liquor into combustion flue gas temperatures as high as 2500° F. Fuel Tech customizes the design and injection strategy for each application since most NO X …
