The use of coal is very wide, China is the world's largest coal producing country, but also the first consumption country. Due to China's "rich coal, lack of oil, less gas" energy resources characteristics and the low price of coal, coal plays an important role in the production and consumption of fossil energy in China. With the development of China's national economy and social development, the demand for coal will continue to grow for a long time in the future. 1) Coal for power generation: more than 1 / 3 of coal in China is used for power generation, and the average coal consumption for power generation is about 370g / (kW; H) of standard coal. Power plants use the calorific value of coal to convert heat energy into electrical energy. 2) Steam locomotive coal: about 2% of power coal consumption, and the average coal consumption index of steam locomotive boiler is about 100kg / (10000 tons ᦇ km). 3) Coal for building materials: it accounts for more than 10% of the coal used for power generation. The coal consumption for cement is the largest, followed by glass, brick and tile.

4) Coal for general industrial boilers: in addition to thermal power plants and large heating boilers, industrial boilers for general enterprises and heating are of various types, large quantities and scattered, and the coal consumption accounts for about 30% of the power coal. 5) Domestic coal: the amount of domestic coal is also large, accounting for about 20% of fuel coal. 6) Metallurgical power coal: Metallurgical power coal is mainly anthracite for sintering and blast furnace injection, and its consumption is less than 1% of power coal. Due to the development of domestic industry and the improvement of people's living standards, the use of coal is greatly increased, and the coal supply is also tense. The main reason for this situation is the shortage of coal in thermal power plants. Due to the continuous drought in the whole southern region this year, the rapid reduction of hydropower generation, the pressure of power generation is transferred to thermal power generation. This year, the coal supply of thermal power plants tends to be tense, resulting in insufficient power generation.

In the premise of no better solution to coal supply, coal consuming units actively carry out coal saving action, and brush Zhisheng Weihua ZS high temperature heat insulation coating on various high-temperature equipment, including furnace inner and outer walls, vaporization pipes, thermal pipelines, flue chimneys, valves and other high-temperature equipment, so as to reduce heat loss, increase flame temperature, reduce exhaust gas temperature, and improve the quality of coal The comprehensive energy saving rate of the power plant can reach more than 15%, and the coal saving amount can reach more than 3%. With the embodiment of coal saving, the cost of unit power generation is reduced and the power generation per unit is increased. The high temperature resistant heat insulation coating of Zhisheng Weihua shows its magic of energy saving again.

With the increase of coal price and the gradual decrease of electricity price, coal consumption units will face more severe test. Only by continuously reducing the cost, reducing the heat loss, improving the energy utilization rate and increasing the power generation capacity, can the power generation enterprises gain a firm foothold in the market, which is of great significance to improve the economy of power plants. Coal is also one of the most serious sources of pollution. The extensive use of coal has caused serious environmental and ecological problems. Under the premise that the energy consumption structure dominated by coal can not be fundamentally changed, efforts to improve the quality of coal has become the fundamental way to prevent and control coal pollution. According to the requirements of environmental protection laws and regulations, the state promotes clean coal technology, vigorously develops coal washing and processing, and encourages clean utilization of coal.

Through washing, processing, such as the preparation of briquetting coal, coal water slurry and coal into efficient and clean oil, gas energy and other clean coal technology means, to minimize its air pollution. China has clearly put forward the overall development strategy of "building a resource-saving and environment-friendly society", emphasizing the "development of circular economy", establishing a number of high-temperature energy-saving material enterprises mainly composed of Beijing Zhisheng Weihua Chemical Co., Ltd., vigorously developing high-tech energy-saving materials, and helping to reduce energy consumption per unit GDP by about 20% and total emission of major pollutants by 10% during the 11th Five Year Plan period And 30% water saving per unit GDP. With the further implementation of China's energy conservation and emission reduction strategy, the importance of coal processing and utilization will be further highlighted.
