6t coal hot water boiler Factory Direct Supply

Steam boiler When should an emergency shutdown when the steam boiler Shanghai encountered the following situations, gas boiler manufacturers need to take emergency shutdown measures: (1) When the steam boiler water level gauge water level drops below the lowest water level, through the "call water when the "law also failed to see the water level. (2) increase the boiler when the water level continued to decline up time. (3) water supply system failure, unable to supply water when the boiler. (4) water level gauge and a safety valve failure, can not guarantee the safe operation of the boiler. (5) When the control valve and the drain valve malfunction when closed lax. (6) when the pressure receiving surface of the waterwall tubes or boiler smoke tubes bulging or cracking occurs, the furnace wall, collapsed down occurs when the front arch. (7) In case of failure of a safety valve, pressure gauge displays the boiler overpressure operation. When by the above situation, should immediately shutdown, should turn off the blowers, the door opened quickly, quick rotation of the grate, the furnace temperature is lowered to withdraw the fire, the coal supply is stopped. When the boiler overpressure, open the emergency vent valve provided on the sub-cylinder is discharged down. When the furnace severe water shortage, should not panic, in order to avoid operational errors. At this time, non-watered furnace. Then reduce oven temperature to find the reasons to be processed.

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 6t coal hot water boiler factory direct supply. 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.

Boiler plant equipment as three major important energy conversion device, fuel chemical energy into heat energy, and the pot was heated using thermal energy to become hot water having a sufficient quantity and a mass (steam temperature, steam pressure) steam turbine for use. The Anyang City, the power company to my company to buy a split 2 tons of steam condensing gas steam boiler for supplying electricity demand. The WNS series split condensing boilers using advanced technology designed to greatly improve the thermal efficiency of the boiler, up to about 96%.

Select gas steam boiler What are the benefits? 1: The biggest benefit is the economic use of gas steam boiler can save a lot of material costs for the business users do not need to spend lots of money to purchase a large amount of coal fuel, just use good cleanliness of natural gas can be released by burning used steam. Gas can also improve the thermal effect of reducing the material input costs of users. 2: Security is well known that natural gas is the safest non-polluting fuel cleanliness good a non-toxic, unlike gas or liquefied petroleum gas leak after precipitation on the ground will burn even cause accidents. Process gas steam boiler during conveying gas selected gas is the most secure, but also easily found after leakage during use and therefore is the most secure way. 3: convenient gas steam boiler in use is the most convenient one, so will much of each enterprise users of all ages. Are used in natural gas pipelines like the convenience of home tap water, and sustainable use will not be any trouble. Eliminating the need to transport coal use and clean-up or stacking cinder and other tedious work. 4: Clean the reason why gas steam boiler in the market to get a high rating, but also because it is clean and not contaminated during use and does not have the black bottom of the pot and no air pollution. So compared to other boilers in use is the cleanest one way, whether for work or residents of the surrounding operation of the enterprise itself or cleaner can not affect physical and mental health.
