For kiln denitrification, the nitrogen oxide generation pathway is mainly generated by the oxidation of nitrogen in the air at high temperature, and the NOx generated in this way is called thermal NOx. Its production is a function of temperature of the flame structure. SCR treatment does not require modification of the equipment body, only for exhaust gas treatment. Green Valley Environmental Protection for the kiln NOX treatment problem, after years of painstaking research, developed the "GRVNES" SCR denitrification system. The system is specially designed to achieve high efficiency operation under the condition of unstable exhaust temperature and gas quality.

Industrial kiln refers to the thermal equipment for melting, heating, gasification and melting of materials or workpieces in the process of industrial production by using the heat generated by fuel combustion or electric energy conversion. Industrial furnace plays an important role in industrial development, widely used in steel, chemical, building materials and other industries, at the same time, industrial furnace is also the main source of air pollution emissions, has an important impact on the environmental air quality.

A kiln is a device built with refractory materials for calcining materials or fired products. General large kiln fuel for heavy oil, light diesel or gas, natural gas. In order to realize the control of kiln emission pollution, industrial boilers need to be upgraded and in-depth treatment, which is an important measure to protect the environment and also the premise to promote the high-quality development of manufacturing industry.

For industrial kiln flue gas denitrification technology scheme, the most mature and widely used flue gas denitrification technology at home and abroad are mainly two kinds:

First, selective catalytic reduction technology (SCR);

Second, selective non-catalytic reduction technology (SNCR).

Both of these two flue gas denitrification technologies have their own advantages and disadvantages.
