With the development of global economy and the enhancement of people’s awareness of environmental protection, especially the control of air pollution, fluidized bed boiler as an important equipment in industry and power production, its flue gas denitrification technology has been widely concerned. Selective catalytic reduction SCR technology, referred to as SCR technology, is widely used in fluidized bed boilers because of its efficient denitrification ability.
The core of SCR denitrification technology is to use a certain catalyst and nitrogen oxide NOx in the flue gas, at a certain temperature under the biochemical reaction, NOx into harmless nitrogen N₂ and water H₂O, through this process, mainly occurs in the catalyst bed, where the role of the catalyst is to reduce the activation energy of the reaction, thereby improving the rate and efficiency of the reaction.
At present, SCR denitrification is one of the technologies with the highest denitrification efficiency, and its denitrification efficiency can reach more than 95%. However, the denitrification efficiency is closely related to the catalytic activity, and the activity of the catalyst is affected by various factors, and will increase with the increase of temperature, especially in the range of 200-300℃, the fastest growth rate, and the activity and efficiency reach the maximum value at 400℃.
SCR denitration technology of Green Valley Environmental Protection has been widely used in the market, with good reputation and significant technical advantages. SCR denitration system independently developed by Green Valley Environmental Protection has independent intellectual property rights and a number of invention patents, with strong research and development capabilities and innovation. The SCR denitrification system of Green Valley Environmental Protection realizes the functions of compact structure design, intelligent, accurate injection, forecast alarm, data acquisition management, remote control and online transmission in the field of ultra-low emission of nitrogen oxides, and the denitrification efficiency can reach more than 95%, and even 98% in some cases. The SCR denitration system of Green Valley Environmental Protection can ensure that the ammonia escape data is less than 3ppm, which means that while achieving ultra-low emissions, it can also effectively control the escape of ammonia and reduce secondary pollution to the environment.
SCR denitrification technology of fluidized bed boiler has become the first choice technology for denitrification of flue gas of fluidized bed boiler due to its high efficiency denitrification capacity and environmental friendliness. Through continuous technological innovation and optimization, SCR denitrification technology will play a greater role in the future prevention and control of air pollution.
