Application(for fertilizer):

Description (used for industry in denitrification in power plant):

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.

coal-fired flue gas denitrification with urea serving as reducing agent.

Because of safety in transport and storage,denitrification technology with urea serving as reducing agent has attracted more and more attention. The mechanism of denitrificaion,technology system and engineering application were reviewed,which were related to Selective Catalytic Reduction,Selective Non-Catalytic Reduction and urea route.Then,the problems existing in the process of application were analyzed,and solving measures were put forward.

Denitrification (DeNOx)

In flue gas denitrification in industrial plants, cement and power plants or waste incineration plants, reducing agents such as urea solution are sprayed into the gas stream. In this process, it is important to generate the optimum drop spectrum from a process engineering point of view and to place it as precisely as possible into the optimum temperature range for the reaction in the gas stream. For this purpose, Lechler offers a wide range of twin-fluid nozzle lances and the appropriate injection system to reliably meet the required limit values.
