Aiming at the problem of nitrogen oxide treatment of boiler, SCR denitration system has been developed after years of dedicated research. This system is specially designed to achieve high efficiency operation even when the exhaust temperature and gas quality are unstable.

What are the substances burned in biomass boilers?

Biomass boiler is a kind of boiler. The boiler using biomass energy as fuel is called biomass boiler. It is one of the representatives of boilers with low pollution and low energy consumption. In the process of using the boiler, not only the fuel energy is consumed, but also the environmental pollution problem is aggravated. The treatment of nitrogen oxides is the most important to reduce the major environmental pollution caused by boiler operation.

There are many kinds of fuels burned in biomass boilers, such as straw, soybean straw, wheat straw, cotton straw, peanut shells, corn cobs, peanut shells, weeds, branches, bark, leaves and other biomass raw materials.

Advantages of biomass boiler:

1. Low pollution.

2. Resistance to combustion.

3. Easily ignited.

How to solve the problem of NOx treatment of biomass boilers?

Although the sulfur content of biomass boiler is low in the combustion process, it still contains particles and ash particles that are not fully burned, which forms smoke and dust pollution, and flue gas treatment is required.

Aiming at the problem of nitrogen oxide treatment of boiler, SCR denitration system has been developed after years of dedicated research. This system is specially designed to achieve high efficiency operation even when the exhaust temperature and gas quality are unstable.

In boiler waste gas treatment, nitrogen oxides are mainly generated by oxidation of nitrogen in the air at high temperatures, and the NOx thus generated is called thermally induced NOx. Its generation is a function of temperature of flame structure. SCR treatment does not need to modify the equipment body, only for tail gas treatment.
