Works gas steam combined fired vacuum boilers and gas development advantages of a steam boiler desuperheater and pressurized combustion product and the main advantage, gas steam boiler desuperheater role and pressurized combustion gas steam boiler 1. Why not suitable for heating? This is because the pressure of the steam boiler is very high, and the requirements of its pipes and accessories is relatively high. So, on this invisible, it will increase costs and expenses. In addition, the installation of a steam boiler is not very simple. Therefore, based on these factors before reaching this conclusion. 2. What is the role of gas steam boiler desuperheater that? Desuperheaters gas steam boiler is generally in the supply pipe, its main role is to reduce the steam temperature, so as to achieve the desired requirements. Desuperheater in kind, type, and the main surface of the two water-jet. For the surface mounting of formula U-tube is a cylindrical tube body, or a recuperative heat exchanger. Water quality which cooling water is no special requirements, mainly in the scope of the low-pressure steam boiler. 3. Gas-fired steam boiler vacuum boiler combustion whether beneficial? If the negative pressure combustion gas steam boiler, specifically refers to a combustion chamber of the boiler, i.e. the furnace, is less than one atmosphere. The means to achieve it, it is achieved by balancing the ventilation system. Pressurized combustion, which does not improve the speed of the combustion gas steam boiler, or to maintain combustion stability. If the conditions are bad, then seal the furnace, combustion positive pressure will increase insecurity, the work environment is unfavorable. Therefore, only the negative pressure combustion to avoid the above problems. The advantages of gas steam boiler is mainly reflected in what areas? Increasingly serious environmental pollution, to people's lives a lot of inconvenience, businesses are keeping up with the pace of the country, respond to national call, in order to energy conservation. Boiler industry is, to a great old-fashioned gas-fired boilers environmental pollution, with advances in technology, people developed a fuel gas steam boiler can use clean energy, today small to say the next gas steam boiler with you. First, the working principle of the burner heat released by radiation is first absorbed water wall heat transfer, vaporization of water boiling water wall, a large amount of steam into the drum for water separation, the separated saturated steam enters the superheater, by radiation, convection continues to absorb the furnace top and a horizontal flue, the flue gases heat the back pass, and superheated steam to reach the required operating temperature. Second, the use of fuel gas steam boiler is the use of clean natural gas energy, no emissions, waste, clean and environmentally friendly, in line with our energy reduction, sustainable development policies, public praise. Third, gas steam boiler applications range: 1 Civil: food processing, such as making noodles, steamed buns, boiled milk, tofu soups and other snacks, food drying, etc.; dry cleaners, laundry room; hotel, sauna and so on. 2. Industrial use: garment factories, chemical production line with steam; supporting food machinery, chemical machinery; tea fermentation. 3. Laboratory: Laboratory with a small amount of steam, teaching experiment. Fourth, the development of the advantages of gas steam boiler 1, natural gas is a clean energy, no waste combustion, waste gas, compared to coal, oil and other energy sources have the use of safe, high calorific value, clean, and other advantages. 2, gas steam boilers safer than conventional boilers, piping is usually aspirated, crew using gas pressure pre-tuned, fuel combustion more fully, the boiler is stable. Gas-fired steam boilers do not need to register the same as conventional boiler inspection. 3, the higher the efficiency of the hot gas steam boiler. Using the principle of countercurrent heat steam boiler, the boiler flue gas temperature is lower than 150 deg.] C, operating thermal efficiency of 92%, 5-10% higher than the conventional steam boiler. 4, gas steam boiler economy is more prominent. Because of the small water capacity, starts a 3-minute produce saturated steam of high dryness and greatly reduce the warm-up time, saving energy. 1 set 0.5T / H steam boiler using energy in a year can save more than 10 million hotel; fully automatic operation.
1. What is a vacuum? Divided into physical vacuum and vacuum industrial vacuum. Vacuum means that no physical space of any particle. Industrial vacuum means a pressure lower than the atmospheric gas space standard. It refers to a thin gas state. It is usually obtained by a special pump. Vacuum vacuum combined fired vacuum boilerss are industrial vacuum.
2. What are vacuum hot water boiler? Vacuum boiler is a vacuum environment, the sealed furnace body negative pressure, so that the furnace body is filled with heating medium water. The heating medium water heated by burning or otherwise, and then evaporated by the heat medium and condensed water into a heat exchanger, then heating the water to be heated by the heat medium water. Vacuum heat boiler indicated: oil, gas, natural gas, natural gas, electricity -> combustion (heat conversion)> heat medium water -> steam condensation heat after boiling -> heat -> Heat Conduction -> vacuum boiler water working principle: the use of water at low pressure characteristics of a low boiling point, rapid heating of the heat medium water sealed furnace body, the heat medium temperature steam generated by the boiling water, the steam condenses on the heat transfer tubes within the heat transfer tubes heating the cold water, to supply hot water purposes. Vacuum boiling point of water and the corresponding table: structural diagram of the degree of vacuum (Kpa) 0-31-54-70-81-89-94-97-99-101 boiling point of water (℃) 10090807060504030200 vacuum hot water boiler:
Characteristics of hot water combined fired vacuum boilers described in Henan fast boiler gas hot water boiler with water in vacuo characteristics having different boiling points at different pressures working environment. At normal atmospheric pressure, the boiling point of water is 100 deg.] C, vacuum gas hot water boiler -0.07Mpa working in a pressure range of the water boiling temperature is lower than the corresponding 93 deg.] C, vacuum gas hot water boiler of the boiler to work under pressure. Combustion temperature of the water rises to the boiling temperature of the boiling water produced the same surface temperature steam, which absorb large amounts of heat volatilization. In this case, the water injected into the boiler heat exchanger, the cold water in the steam tube is an outer tube is heated into hot water then flows, steam is condensed out of the cold water cooled tube heat exchanger into water droplets. This completes the process water circulation in vacuo. 1. In the flue tube mounting closed fins increase the heat transfer effect, so that more concentrated arrangement. 2. Integral with a square configuration, personalized spraying, separation shape appearance. 3, large furnaces can techniques: effective to increase the heat radiation per unit area, to reduce NOX emissions. 4. Pure ensure high boiler water boiler water scaling, oxidation. Fives. All wet back shell using tricyclic structure, static heating, large heat balance. 6, all active control system, no staff on duty. Simple pulse level detection circuit unique structure, reliable performance. 8. Out of the water temperature display is doubled, easy to control operation of vacuum hot water boiler and crumb. 9. High quality multilayer centrifugal glass wool insulation, heat losses are small. Vacuum hot water boiler with three gas-pressure safety protection system: automatic safety explosion relief valve: When the pressure inside the boiler continues to rise, the explosion-proof valve due to excessive pressure and burst, releasing the pressure inside the boiler, to ensure the safe operation of the boiler; a digital pressure switch : imported from Japan digital pressure switches, ready disassembly. Detecting the degree of vacuum changes the boiler, when the pressure is too high, the end of fire; explosion-proof valve automatic safety alarm: In special cases, when the pressure in the boiler becomes slightly positive pressure explosion-proof safety valve controlled vibration alarm, turn off the power boiler.
