Steam boilers What is the function? Too much in the form of szl water tube straw boiler %7c biomass steam boilers, took an ordinary four tons fast load steam boiler, for example. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Biomass boiler is a kind of boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler, biomass stove, biomass thermal oil heaters, vertical raw biomass boilers, biomass boilers and other horizontal. Works steam boiler water is heated and converted to steam in the steam drum, the fire gives off heat in the furnace. Let me talk boiler, say the pot. This boiler is a water-cooled drum boiler. Around the drum in the two regions is provided two return tubes pyrotechnics, smoke box and in front of the drum to turn back. In the boiler drum and the lower connection between the tank, a downcomer and a cooling pipe, constituting the framework of the combustion chamber. An upper drum provided with a vapor separator, in order to reduce the outflow of water from the steam. Heating surface of the pot to the drum, and a lower cooling pipe pyrotechnic tube. A combustion section and drive means consisting of a chain grate, a combustion chamber pot grate frame composed of frame. It is surrounded by refractory material. By the combustion of the coal into the coal hopper, the thickness of the coal seam is controlled by the gate, while the air is sealed in front. Blast into the lower part of the combustion chamber is the place, this big boiler resistance, it is necessary to force the blast. Burning ash through the rear grate Eagle iron is discharged, and the outside of the furnace through the slag discharged from the device. Smoke from the rear of the boiler, the boiler return pipe from the first pipe, the second pipe from the reflux to the back, and then enters the precipitator ash is then discharged through the chimney draft fan. Induced draft fan is not only the smoke emissions, but also the negative pressure necessary for operation of the boiler. Steam boiler is a pressure vessel, the safety device is essential. Basic boiler water level gauge, pressure gauge, safety valve, thermometer, water can be added at an upper portion of the electric pump pressure, when the pump power and steam may also be used. Boiler water must be softened, and water treatment equipment.
Boiler manufacturers analysis of the main types of szl water tube straw boiler %7c biomass steam boilers What? As we all know, the boiler is an energy conversion device, it is one of the most common products to generate steam, many industries are widely used in the production of boiler operation. However, a variety of boiler type, different applications of different brands and models of boilers, boiler manufacturers to provide consumers now Linyi analysis of the main types of steam boilers which, as follows: first, coal-fired steam boilers. Linyi influential learned fired steam boiler plant is a traditional industrial boilers to burn coal as a material, its main characteristic is fueled with low heat, and more low-quality coal ash materials. Linyi boiler manufacturers also learned that the coal-fired steam boiler affordable, low cost combustion, power station boilers using mostly coal-fired boilers can save a lot of high-quality fuel for the enterprise. Second, biomass steam boiler, boiler manufacturers Linyi analysis, the main fuel biomass steam boiler that are environmentally friendly green renewable energy, fuel and raw materials mainly from the steam boiler of crop straw, sawdust, bark, and so on. Therefore, biomass energy from biomass steam boiler, high environmental performance, and widespread use of biomass steam boiler can also reduce dependence on fossil fuels. Third, the fuel steam boilers, boiler plant Linyi learned advanced steam boiler fuel use in the industry is more extensive, less fuel steam boiler equipment investment, and fuel burn rapidly, and there is no furnace coke problem occurs, the furnace volume heat higher load, higher cost. Fourth, gas steam boilers, boiler manufacturers that Linyi, gas steam boiler based on natural gas as a fuel, it has efficient, clean and green maximum advantage. Linyi boiler burning natural gas companies learned that no impurities, the boiler and related accessories there is no damage, the longer gas steam boiler service life. Moreover, the analysis can be learned from the Linyi boiler manufacturers, such as constructed according to the steam boiler can be divided into: vertical steam boilers, horizontal steam boiler, and a steam boiler in accordance with the size of a single return can also be divided, double return, three-pass boiler structure. So Linyi boiler manufacturers recommend that consumers in the choice of a steam boiler, set to combine their needs and purposes, given the nature of the steam boiler, steam boiler select the most appropriate for their own use.
