There are many boiler industries in China, and the environmental pollution caused by coal-fired industrial boilers is also very serious. According to the national emission requirements, new boilers are needed to improve our current environment. Biomass boilers are a new type of boilers.

Biomass boilers can use crops and other wastes as the main fuel. Compared with other coal-fired boilers, biomass boilers are more environmentally friendly and meet the requirements of the national emission policy. However, biomass boiler fuel contains a large amount of nitrogen, sulfide, etc., which will also produce polluting gases after combustion, which undoubtedly has a great impact on the environment, Biomass boilers also need to purify the flue gas generated by their combustion, and need desulfurization and denitrification.

Aiming at the nitrogen oxide treatment of biomass boilers, after years of intensive research, the "grvnes" SCR denitration system has been developed. This system is specially designed to operate with high efficiency in case of unstable exhaust temperature and gas quality. In the treatment of waste gas from biomass boilers, nitrogen oxides are mainly generated by the oxidation of nitrogen in the air at high temperatures, and the generated NOx is called thermally induced NOx. The amount generated is a function of the temperature of the flame structure. SCR treatment does not require modification of the equipment body, only for tail gas treatment, and the specific process also needs to be combined with the actual situation and emission standards.
