Application of SCR denitration technology in glass furnace

Nanjing Baisheng Glass Technology Co., Ltd. and Nanjing Baisheng Kiln Engineering Co., Ltd. were established in February 2006 and January 2014 respectively. Is a professional company engaged in glass factory (kiln) design, kiln (equipment) construction and installation and glass production technical services. The company mainly serves the glass factory design of flat glass, photovoltaic calendered glass, electric light source glass, daily-use glass, water glass and ceramic frit production lines, glass engineering installation and construction, firing and baking kiln, commissioning and related technical training, technical services, and professional companies for hot and cold repair of glass kilns.

Next, we will introduce the application of SCR denitration technology in glass furnace:

Denitrification of glass furnaces has always been a difficult problem in China. The successful application of SCR denitrification process in Wujiang CSG has broken through two firsts in China: the first SCR denitrification project in float glass industry; The first domestic high-temperature electrostatic precipitator is a milestone project of denitration in glass furnaces in China. There are primary and secondary measures to control NOx in glass kiln, and the secondary measures include SCR (selective catalytic reduction) and SNCR (non-selective catalytic reduction). According to the characteristics of float glass production process, SCR denitration technology and high temperature dust removal process are suitable for denitration of glass furnace flue gas. Due to glass raw materials and various additives, the content of alkali metal oxides in flue gas dust ash is high, which is an important cause of catalyst alkalosis. The adverse effects should be fully considered in the design of SCR system and the selection of catalyst. In order to prolong the service life of catalyst, a high-temperature electrostatic precipitator is set in front of the reactor.
