150 hp horizontal gas steam boiler for oil refinery
Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
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 14th biomass steam boiler in sugar industrys, so in general we are talking about heating boilers often refers to pressure hot water boiler. 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.
Wood fired steam boiler is a kind of biomass fired steam boiler which takes clean and renewable biomass energy as its fuels. With the improvement of people’s environment-protection consciousness, biomass fired steam boiler is becoming more and more popular.
