15T Hr D Type Water Tube Coal Boiler Manufacturers
A: Commercial current commercial gas 15t hr d type water tube coal boiler manufacturers main use is for supermarkets, hospitals, schools, hotels, residential (mainly the center of the city, convenient gas facilities area), bath, etc., to provide heating or bathing water, hot water. Since the gas in the ash, low sulfur and nitrogen than coal combustion, very small amount of dust in the flue gas, the state emission standards easy to achieve the required gas appliance, it can greatly reduce the pollution of the environment, environmental performance it is good. Boilers and combustion gas on the accessory device does not require gas, slag, dust removal machines, etc. grate, boiler investment saving equipment, is therefore suitable for commercial applications. Two: with factory workers using direct gas boiler piped gas powered, no gas storage, health conditions, can greatly reduce labor intensity and improve working conditions and reduce the operating cost, operating cost savings, space and labor . Since the smoke pollution, convection bank bear little corrosion, heat transfer effect, strong radiation heat, exhaust gas temperature is low, the thermal efficiency is significantly improved, so the main industrial gas boiler for power generation, industrial gas boilers of gas used may be generally natural gas, blast furnace gas, producer gas and so on. Three: Civil domestic gas boilers (boiler) is mainly used for daily household hot water, bath and hot water heating. In reducing equipment maintenance, gas burning boilers coefficient simple equipment, thus requiring less maintenance equipment maintenance, long life heated tube, gas boiler is simple to operate and easy to achieve automatic control.
Henan difference fast 15t hr d type water tube coal boiler manufacturers steam boiler steam boiler is a steam boiler with ordinary steam production machinery and equipment, generally used gas, or coal gas as a fuel, there are an electric steam boiler. Henan fast boiler for the inspection of the steam boiler is a steam boiler gas, fuel oil, gas, and it is common conventional steam boiler with the following differences: "steam boiler supervision norms" and the forthcoming introduction in June next year the new pot rules " boiler safety technology to monitor the specifications "are clearly defined steam boiler needs to be regulated by the state. In other words, users looking to buy a steam boiler plant boiler installation and can not be used directly. Before installation To pot seized by the approval and registration required for installation, and the need for inspection on a regular basis, usually one year during the annual inspection. But there are some of the steam boiler does not require registration and annual inspection, the old rules and the new pan pot regulations stipulate a water capacity less than 30L steam boiler is not within the scope of the surveillance. Because the water capacity of 30L water capacity than at home with a water heater are also small, so there is no risk of explosion, we do not need supervision. Henan water capacity fast boiler steam boiler 26L, belongs steam boiler does not require supervision. Steam boiler explosion hazards generated is amazing. In many steam boiler explosion in the boiler room were razed to the ground, the annual explosion of a steam boiler will be the first to cause casualties and significant economic losses. Henan fast boiler steam boiler is to achieve the ultimate, the boiler body through the scientific design, water capacity is very low, only 26L, itself, there is no risk of explosion on security. The thermal efficiency of conventional steam boiler is only 80%, while the party Henan boiler thermal efficiency of fast gas steam boiler can reach more than 93%. Henan plus energy-saving system fast boiler control systems, the actual energy savings up to 30%, running down a year could save hundreds of thousands of operating costs. The Henan fast boiler steam boiler without boiler room, an area itself is small, you can put in the basement or roof, it can also be placed directly next to the device requires the use of steam. Saving the cost of laying pipe network construction costs and the boiler room, a significant reduction in the use of the initial investment.
What part of the body including the 15t hr d type water tube coal boiler manufacturers? What role have? It comprises a crucible and the furnace: a body: refers to a soda boiler system, which is superheated by the reheater water preheating system and a vaporization system composed of dry steam. The role of the high-pressure boiler feedwater heater through the further heating evaporation, for the purpose of blowing rpm turbine to do work. System configuration: economizer, the drum, the downcomer, water wall, superheater, reheater, economizer high pressure heater outlet feedwater is introduced into the economizer, economizer tube within an outer absorber tube gas and fly ash heat, water temperature increases to about 300 ℃ drum water out from the economizer line into the bubble along the top of the boiler disposed outside. Drum lower half of the water, the upper half steam. Unsaturated high pressure drop along the water reaches the bottom of the bubble tube at the bottom of the lower header outside the boiler, a number of pipes mounted in parallel on the bottom of the boiler around the lower header, the furnace by the upward flow of the absorbent in the central flame of the inner tube wall pipe convective heat radiation heat transfer and high temperature flue gas. Since the heat absorption is much less than the water vapor, the water wall within a predetermined vaporization rate can not be greater than 40%, because the working fluid will easily melt late Wall water absorbing tube rupture occurred. Downcomer role is water vapor to the bag waterwall lower header, to establish a water circulation. Wall water in the tank through the second line and then returned to the boiler water wall, the water in the drum is completed, the downcomer, the circulation between the superheater waterwall separated in the steam drum is withdrawn from the top of the drum, laying into the first top ceiling superheater, then through the cladding wall superheater, low temperature superheater, platen superheater, to a high temperature superheater, after reaching the rated temperature of the heating steam turbine into work. After the reheater boiler is also provided with a large reheat means that steam from the high pressure cylinder acting, temperature and pressure of the exhaust gas is reduced, the exhaust gas is heated to a reheater, and then returned to the steam turbine, a low pressure cylinder continues to work. Furnace body: it refers to a boiler furnace combustion system and its role is to heat the fuel combustion in the furnace as much as possible and transfer heat to the working fluid, and the completion of the water wall and economizer water water heated in the tubes, heated in the dry steam superheater and reheater tubes, the air in the air preheater tube heated. The system consists of: a combustor, furnace, air preheater. Production process: raw coal from the coal by the belt conveyor to the higher field position of the coal bin, the bottom of the coal from the coal bin out through the stoker evenly into the ground to a coal mill. Nature of the atmosphere via the air inlet of the blower is arranged in the vertical flue to the boiler air preheater, subjected to heat of the flue gas, flue gas waste heat recovery. About 250 degrees out of hot air into two air preheater from: one directly introduced into the burners of the boiler as secondary combustion air into the furnace; the other can be introduced into the mill inlet for drying, transporting coal, which said primary air portion of hot air. Excellent flow of drying gas and pulverized coal mixture powder consisting of primary air, conveyed via line separator to be coarse coarse separator, the separated coarse powder inlet sending back regrind mill, and eligible powder and primary air mixture into pulverized powder separator, gas separation, the separated coal fines into storage to save it from the powder according to the magnitude of the thermal load of the boiler, the control of coal flow discharged coal warehouse bottom while separated from the fines separator as the primary air pulverized coal power delivery, after the pressing of mill powder mixture with the gas mixture into a fine powder fed again by a burner into the combustion furnace.
