Forging heating furnace is an important metal pre-forging heating equipment, which is widely used in petroleum, chemical industry, metallurgy, machinery, heat treatment, surface treatment, building materials, electronics, materials, light industry, daily chemicals, pharmaceuticals and many other industries.
During the production process of forging heating furnace, harmful gases such as sulfur dioxide (SO2), nitrogen oxides (NOX), soot, carbon monoxide, and hydrogen sulfide will be produced. One of the key challenges is the source control of nitrogen oxides in high-temperature industrial furnaces, which also generates vibration and noise during processing.
If the exhaust gas temperature of the heating furnace is too high, the exhaust gas temperature will lead to the heat of the flue gas, waste energy, and at the same time, accompanied by air pollution, which will have a significant impact on the health of the workshop staff and the surrounding residents. In order to solve these problems, it is an effective way to improve the combustion process and heating medium of the furnace. For example, the use of advanced technologies such as natural gas heating furnaces, electric furnaces, light oil reverberatory furnaces and heating media instead of coal and heavy oil can make the production process more environmentally friendly, while improving the thermal efficiency of the furnace and reducing heat loss.
In the production process of forging heating furnace, nitrogen oxides (NOx) will be discharged, which not only causes pollution to the environment, but also threatens human health, nitrogen oxide transformation is currently crucial, SCR denitrification technology, is a selective catalytic reduction technology, is currently one of our most mature denitrification technologies.
In the production process, fuel combustion, heating and other processes need to be effectively treated and controlled by nitrogen oxide treatment. Our SCR denitrification system does not transform the furnace body, only directly treats the furnace exhaust gas, does not affect the thermal efficiency of the boiler, the furnace can run stably under any load, its emission standard is below 30mg m3, there is no potential safety hazard and CO exceedance, and even the treatment efficiency reaches more than 95%. At present, we use the selective reduction method (SCR), the flue gas enters the SCR reactor, and the NOx is reduced to harmless N2 and H2O through the catalyst modules of each layer.
The nitrogen oxide treatment of forging furnace is of great significance to protect the environment and promote the green development of the industry. In order to achieve this goal, we need to continuously develop and apply more advanced and efficient pollution control technologies to achieve the healthy and sustainable development of the industry.
