The Efficient Denitrification Technology of SNCR
The full title of SNCR is Selective Non-Catalytic Reduction, which is a mature commercial NOx emission control and treatment technology. This technology refers to the flue gas denitrification technology that using reducing agent (such as urea/ammonia) to selectively reduce NOx to N2 and H2O in a certain temperature range (800-950℃) without catalyst.
主要内容

Pyneo has the high-efficiency denitrification technology of SNCR with independent intellectual property rights, which is mainly composed of reductant storage system, solutions preparation system, solutions storage system and furnace injection system. Pyneo's SNCR high-efficiency denitrification technology won the National Natural Science Second Prize and Annual Hangzhou Excellent New Product and New Technology Award, registered as a scientific and technological achievement in Zhejiang Province, and confirmed as a provincial industrial new product.
