Introduction
With the popular trend of environmental protection, desulfurization projects in thermal power plants have attracted more and more social attention. With the development of industry, as the number one killer of heavy air pollution, the emission and treatment of sulfur dioxide is imminent. In the field of environmental desulfurization in thermal power plants, limestone gypsum desulfurization process is a widely used desulfurization technology in the world. This technology has high utilization rate of absorbent, low calcium sulfur ratio and desulfurization efficiency of more than 95%. It is a common method for effective desulfurization in thermal power plants.
Limestone is a cheap and effective desulfurizer. In the wet desulfurization unit, the purity, fineness, activity and reaction rate of limestone have an important impact on the desulfurization of power plant. Guilin Hongcheng has rich manufacturing and R & D experience in the field of limestone preparation in power plant, and has developed an excellent complete set of solutions for the details of desulfurization system in thermal power plant. We are equipped with an after-sales team with superb technology and strong service awareness to track the later system installation, commissioning and maintenance, and help customers design a scientific and reasonable wet desulfurization production line.
Application area
Boiler heating industry: small cities mainly use boiler rooms as the central heating source, and pulverized coal is the main fuel of small and medium-sized coal-fired boilers.
Industrial boiler: in modern industrial production, industrial boiler is a common thermal power equipment with wide use, large quantity, coal-fired and large fuel consumption.
Blast furnace pulverized coal injection system: blast furnace pulverized coal injection is not only conducive to coke saving and increasing production, but also conducive to improving blast furnace smelting process and helping the smooth operation of blast furnace, which has been widely valued by countries all over the world. The coal injection system of blast furnace is mainly composed of raw coal storage and transportation, pulverized coal preparation, pulverized coal injection, hot flue gas and gas supply. Pulverized coal injection can improve the utilization of carbon monoxide and the hydrogen content of gas in the furnace. Pulverized coal preparation is an important part of the whole system. It adopts high-yield, environmental protection and energy-saving pulverized coal pulverizing equipment, which can improve coal production and meet the demand of pulverized coal market.
Preparation of pulverized coal in lime kiln: with the development of society, there is a great demand for lime in many fields such as metallurgy, chemical industry and building materials, and the quality requirements of lime are higher and higher, which puts forward higher requirements for common coal-fired systems. As a manufacturing expert of pulverized coal pulverizing equipment, only by continuously enhancing the manufacturing level of pulverizing process can we adapt to the changing and developing market demand. Hongcheng environment-friendly and efficient pulverized coal preparation equipment is widely used in the field of lime kiln preparation and is very popular.
