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 paddy rice husk biomass fired steam boilers, 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.
The United States is our national enterprise, one of the world's top 500, with very bright glory on the world stage. US air-conditioning as a subsidiary branch, with a very large market competitiveness. 2016, Hubei US air-conditioning due to market demand to expand production lines, need to purchase paddy rice husk biomass fired steam boiler to provide energy support for the new production line. After the boiler industry for a number of enterprises contrast, is determined to cooperate with the fast boiler, buy a whole 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
UAE have many industries which need boiler for example sugar plant, textile plant, cement plant, aac block plant, etc. Steam boiler is important equipment in industrial processing, ZG Boiler is the industrial boiler leader manufacturer and supplier in China. We supply many types boiler, there are gas & oil fired boiler, coal fired boiler, biomass fired boiler, waste heating boiler, CFB boiler power plant boiler, AAC autoclave.
The solid fuel fired and biomass fired boilers are mainly used in hotel, hospital, university, central heating, refineries, utilities, petrochemical, chemical, paper and pulp, steel and iron, food processing, power station, and other major processing industries. Solid fuel boiler is chain grate type boiler burning coal, biomass or mix-firing both. It adopts membrane water wall, with economizer in the rear of boiler. High combustion efficiency, energy saving and low emission. Three-pass tube design incorporating a wet back turnaround that eliminates the need for rear door refractory. Larger steam disengagement area providing high quality steam, larger steam storage capability for quicker response to sudden steam demand. Equipped with PLC-based control system to realize automatic operating in start-up, standby and shutdown control Designed, constructed and stamped in accordance with the requirements of the American Society of Mechanical Engineers.
