Apart from these efficiency, there are some other losses which also play a role while deciding the boiler efficiency and hence need to be considered while calculating the boiler efficiency. However, the most important factors need to be considered are boiler combustion efficiency and boiler thermal efficiency.
In recent years, with the strengthening of China's environmental protection efforts, high low emissions, efforts to clean gas boiler gradually become the mainstream products on the market. However, to get gas boilers to maintain normal operation, there is more than boiler, but also supporting auxiliary equipment and instrumentation valves. Among them, the instrument is a major control the operating parameters of the boiler accessories, is very important.
Select the reason for the low nitrogen gas paper mill boiler which with the development of science and technology, more and more companies use low nitrogen boiler equipment, but many users do not understand the benefits of cost-efficiency boiler equipment. By comprehensive comparison of all major brands of equipment characteristics boilers and old customers credit rating, obtained low nitrogen boiler equipment than three salient features of the general conclusions low nitrogen boiler. Three outstanding characteristics of low nitrogen boiler is better than ordinary boilers. 1. meet emissions testing of standard low emission of toxic nitrogen boiler is much lower than the conventional type boiler. Sampling standards in full compliance with national standards of environmental protection departments, the use of FGR core technology advanced flue gas circulation and surface completely mixed combustion. Oxygen generated in the boiler manufacturing process, the nitrogen content can meet international standards for emissions, because most devices are cost-effective low-carbon low nitrogen imported pure boiler. 2. The selection of high quality, long life equipment in many lower smoke tubes seamless and efficient condensing device. These fine materials to ensure a higher heat transfer capacity of boiler equipment, enterprises save a lot of costs, on the other hand, the quality of materials is also excellent. Excellent production to ensure low nitrogen boiler for longer than the average life of the boiler low nitrogen. three. Operational safety, worry-free sale with the development of science and technology, intelligent technology in the field of low nitrogen boiler equipment has also been widely used. High performance, high cost boiler usually intelligent control, the operator need not operate like an ordinary boiler as switching field. But through the intelligent computer control system in the control room to complete the entire production, greatly ensure the personal safety of operating personnel. Low nitrogen boiler equipment is not only good quality, long service life, operational intelligence, reduce accidents, and improve after-sales service and other prominent features, but also has the characteristics of quality and cheap. A new low-nitrogen boiler quotes report shows that the majority of high performance and low cost of low nitrogen equipment prices have absolute advantage. These features are advantages of low nitrogen facilities. It is increasingly popular with users of reasons.
Shanxi Province is located in China's western areas north of the Loess Plateau, the terrain finished solid, rich products. Thanks to energy supply and price advantage of coal, coke, metallurgy, electric power and other coal industry, the rapid rise of the formation of Shanxi coal-based economies of resource-based industries.
Shanxi Province, but had coal and Xing, but also because of the coal and sleepy. According to the report, "2017, Shanxi Province, coal accounted for the proportion of energy consumption up to 84.6%, higher than the national average of 24 percent, it is 2.9 times as much as the global average of Shanxi to 1.6% of the national land area, consuming about 10% of national coal amount. for Shanxi, winning the battle of blue sky, coal pollution can be effectively controlled is the key.
According to the "Blue Sky Battle Shanxi three-year action plan," issued in July this year (hereinafter referred to as "" Shanxi three-year action plan '') planning requirements, by 2020, sulfur dioxide, total nitrogen oxide emissions are lower than in 2015 more than 20%, compared to strive average concentration of sulfur dioxide in 2015 fell about 50%. Among them, 2020, total coal consumption in 8 cities in key areas to achieve negative growth, the province's coal consumption in primary energy consumption share dropped to 80%, the proportion of the province's coal consumption of coal accounts for more than 55%.
According to Shanxi Province Bureau of Statistics latest data, as of the end of August this year, Shanxi Province, the outgoing power 50.67 billion kwh, up 21.1%; the first half of Shanxi new energy consumptive power grid to complete 15.6 billion kilowatts, an increase of 58.2%, new energy abandoned consumption fell 90.6% year on year, abandoned electricity rate fell 10.2 percentage points.
The past two years the province shut down 52 coal mines, quit production capacity 45.9 million tons, subtract coal production capacity of 9.25 million tons per year, the completion of energy-saving 18 million kilowatts of coal-fired power plants, coal-fired power plants province's average coal consumption of electricity of 320 grams per kilowatt-hour of standard coal. In the first half of this year, the province's above-scale industrial Shanxi coal industrial added value increased only 0.8%.
