SNCR flue gas denitrification device taking urea as a reducing agent for denitrification

Urea, also known as carbamide, is an organic compound with chemical formula CO(NH2)2. This amide has two –NH2 groups joined by a carbonyl (C=O) functional group. ... Urea is widely used in fertilizers as a source of nitrogen (N) and is an important raw material for the chemical industry.

Because of the safety in transport and storage denitrification technology with urea serving as reducing agent has attracted more and more attention.

Generally speaking, denitration is to spray ammonia or urea solution into the furnace after atomization to remove nitrate (i.e)Nitrogen oxides (mainly nitric oxide and nitrogen dioxide) are removed from the flue gas and become harmless to the air technology, namely selective non catalytic reduction technology, is one of the main flue gas denitration technologies at present different reducing agents have different reaction temperature ranges,this temperature range is called the temperature window. When the reaction temperature is too high at high temperature, due to the decomposition of ammonia, the NOx the reduction rate decreases. On the other hand, when the reaction temperature is too low, ammonia escapes The increase of fugacity will also make NOx Reduced reduction rate. SNCR The key of the process technology lies in the reductant injection system

The reducing agent must be injected into the most effective temperature window area in the furnace as far as possible, That is, ensure the spraying as much as possible the added reducing agent is well mixed with the flue gas at an appropriate temperature, on the one hand, the reducing agent can be improved on the other hand, smaller ammonia escape can be controlled.

This set of denitration equipment includes metering pump station system (metering pump, pressure gauge, pipe fittings, valves, base and electric control box)

Denitration spray gun (nozzle, gun rod, protective sleeve, mixer, quick connector, quick release clip, etc.) (urea solution pipeline, compressed air pipeline)
