7000 kw coal fired hot water boilers
Industrial boiler market share rise, to the current trend of energy-saving industry, industrial boilers are mainly used in metallurgy, chemicals, coke, cement, paper, shipbuilding and other industries, mainly through heating boiler, steam production unit each to provide the required or hot water. Different transformation and power industry, industrial boilers since often small cell capacity, installed at the rear end of expensive desulphurization and denitrification apparatus is very uneconomical, so the transformation of coal will be the main alternative route, the coal gas, biomass fuels, cleaning three coal technology route, clean coal will assume the main task. By the end of 2011, the total industrial boilers reach 58.5-60 million units, of which the boiler, the capacity accounted for more than 80% of coal-fired boilers, boiler capacity is less than the number of 35 tons / hour of 96% of the total, while 10 accounting tons / hour up to 80%. Meanwhile, the average thermal efficiency of industrial boilers only 60%, 20-25% lower than in other countries. The country's industrial kilns more than 160,000, concentrated in building materials, metallurgy, chemicals and ceramics and other industries, the annual coal consumption of 300 million tons. The average heating furnace thermal efficiency of only 40%, 10-30% lower than in other countries. A wide range of large industrial boilers in China, the average capacity of small and dominated by coal. Although China's coal-fired industrial boiler design productivity gap compared with foreign small, but the actual operating efficiency of only 65%, 10% -15% lower than the advanced level. Industrial boilers with maximum downstream chemical materials and chemical products manufacturing market size, non-ferrous metal smelting and rolling processing industry, petrochemical industry market size is large, in addition, the market size paper and shipbuilding industries is relatively small, moderate growth in the cement manufacturing industry . Overall, the future of Chinese boiler market demand is still the main metallurgy, chemical and petrochemical three coking industry, and paper, cement and other industries demand is relatively weak, shipbuilding recession has not slowed. Industrial boilers, especially coal-fired industrial boilers for energy saving is important for achieving the overall goal of energy conservation.
Industrial boilers and heating boilers What is the difference? Industrial boiler product in two ways, one steam used to generate electricity or gas, such as steam vaporized available fertilizer plant, coal as raw material, synthetic fertilizers, which is typical of industrial boilers, coal-fired industrial boilers still account for a large most gas is generally waste heat boiler for recovering waste heat. Industrial boilers commonly circulating fluidized bed boiler industrial boiler thermal power equipment is important, our country is today the world's largest production and use of boilers country. China's manufacturing industry is established and developed after the founding of New China. The term "industrial boiler" in the late 1930s, with the boiler thermal power generating units with capacity increasing, in order to distinguish high-capacity power plant boiler gradually adopted. Modern large-scale industrial boilers evaporation capacity has reached 100 to 200 tons / hour. Industrial boiler structure type in the structure can be divided into fire cartridge type, water and fire tube type 3 class. ① fire tube boilers; it is an early boilers, fire tube containing only water in the boiler twelve heating pot shell fire cylinder combustion means. Low thermal efficiency, large volume and steel consumption, since substantially no production 60s. ② fire tube boiler: it is in the vertical or horizontal potshell in addition to the fire tube, a plurality of means further smoke tube. The fuel in the combustion chamber high temperature flue gas produced after combustion smoke flows through these pipes heating pot of water, and then discharged into the chimney. Compared with fire tube boiler, since it is the number of multi-smoke tube, heated area increases, the exhaust gas temperature is low, high thermal efficiency, and the consumption of steel are relatively small volume of the boiler. FIG. 1 is a horizontal tempering tube boiler. When evaporation fire tube boiler is generally not more than 15 t /, working pressure not greater than 1.6 MPa, the thermal efficiency of coal is generally about 70%, of all oil-fired boiler automatic operation, the thermal efficiency can reach 85%. ③ water tube boilers: mostly used for larger capacity, higher pressure industrial boilers. Water tube boiler has a natural circulation type and DC two. Natural circulation water tube boiler with a single drum and double drum and other structures. Figure 2 is a double drum water tube boiler. Such boilers generally disposed in the convection tube economizer, an air preheater and sometimes, in order to reduce exhaust gas temperature. When coal efficiency up to 80% higher when the fuel. No drum DC industrial boilers, and the tubing coiled behind the inner wall of the furnace tubes of the convection heating surface composition. From the end of the tube into the water supply, the steam output from the other end. Industrial boilers small current, typically with separator and automatic control devices. The fuel and fuel combustion equipment is widely used in variety of industrial boilers, coal (bituminous coal, anthracite, lignite and coal waste, etc.), oil (heavy oil, residual oil and diesel, etc.), gas (natural gas or various industrial by-product gas) plant and urban waste (wood, bagasse, black liquor and waste, etc.) and so on. Therefore, industrial boiler combustion equipment is also varied. There layer belongs chain grate combustion apparatus, the feed grate, reciprocating grate, vibrating grate, chain grate stoker plus the like (see grate). Also useful way of fluidized bed combustion (see boiling furnace). In the evaporation of 65 t / h coal-fired industrial or larger capacity boilers generally use coal. Heating boilers boiler belongs to the category of civilian life, as people's safety awareness, and after 2000 are based on building heating hot water as heat medium, it does not allow the use of steam boilers, so in general we are talking about heating boilers often refers to pressure 7000 kw coal fired hot water boilers. There are many types of heating boilers, their classification is mainly divided in accordance with the fuel type, fuel heating boilers can be divided according to the different electric heating boiler, oil heating boiler, gas heating boilers, coal-fired heating boilers, biomass heating boilers. Which includes fuel: diesel, kerosene and heavy oil; which includes gas: Natural gas, LPG, city gas and biogas.
The recent good news story: Union Square soon Group was named the provincial Federation of factory affairs leading group as "micro-small and medium private enterprises in Henan workers' congress building demonstration units" honorary title. Win the title, is inseparable from the efforts of all labor union workers, they work with their own solid foundation, effective operational mechanism and splendid achievements successfully nominated and award winning. Over the years, the Labor Union under the correct guidance of urban levels of trade unions, under the correct leadership of the Party, Comrade rely on the staff, smooth internal management channels, good to play the democratic management of conflicts "relief valve" business "stabilizer" and developing the "catalyst".
