The application of hot blast stove is very wide, and it is used in many industries and fields, whether it is chemical industry, pharmaceutical industry, painting industry, agricultural production, food processing, building materials industry, environmental protection field and metallurgical industry, the use of hot blast stove plays an important role.
In the process of blast furnace ironmaking, the use of hot blast furnaces will produce nitrogen oxides (NOx), which is a pollutant harmful to the environment and human health. The nitrogen oxides (NOx) produced by hot blast furnaces are related to the combustion process. In order to meet environmental protection standards, reduce the impact on the environment, and meet environmental protection requirements, it is necessary to optimize the combustion conditions, further reduce the combustion temperature, reduce oxygen excess, shorten the residence time of the flue gas in the high temperature zone, etc., which can reduce the generation of thermal NOx. Before flue gas discharge, flue gas denitrification technology, such as selective catalyst reduction technology (SCR), is used to reduce NOx in flue gas to nitrogen and water to achieve ultra-low emissions. SCR denitrification technology is the most widely used flue gas denitrification technology at present, especially suitable for flue gas treatment of hot blast stove.
Our SCR denitrification equipment in the field of ultra-low emission of nitrogen oxides to achieve compact structure design, intelligent, accurate injection, warning, data collection management, remote control, online transmission and other functions, can achieve ultra-low emission while ensuring ammonia escape data less than 3ppm. Have a strong comprehensive competitiveness.
SCR denitrification technology can effectively control nitrogen oxide emissions, meet environmental protection requirements, promote the steel industry can protect the environment at the same time, achieve sustainable development, and contribute to the green development of society and economy.
