The gas steam boiler is a heat energy conversion device that uses natural gas, liquefied gas, city gas and other gaseous fuels as fuel, burns the heat released in the furnace, heats the water in the pot, and vaporizes it into steam. The water is constantly heated by the energy released by the combustion of the gaseous fuel in the boiler (pot), the temperature rises and the pressurized steam is generated, and the boiling point of the water rises with the increase of the pressure, the pot is sealed, the water vapor The expansion inside is restricted to generate pressure to form thermal power (strictly speaking, the water vapor of the boiler is formed by constant pressure heating of water in the drum to re-vaporization of saturated water) as an energy source.
Divided according to the heated structure, China's current industrial boilers can be basically divided into the following three categories: water tube, fire and water tube, fire-tube. Details are as follows.
Maintenance of the boiler plant food which gas boiler in use for some time, people should arrange maintenance work at the gas hot water boiler, in order to better safeguard the operation of the gas hot water boiler, and can extend the life, now completed three maintenance methods, for your reference. First, boiler and pressure maintenance plant is suitable for short-term food production or backup boiler shutdown. (1) shutdown, boiler water is completely drained furnace slag fouling and cleaning, plus qualified soft water. (2) Summer boiler water temperature should be maintained at about 10 ℃, should not freeze in winter boiler water, all valves should be empty periodic low heat or steam oven water heating boiler closure adjacent the regular use, therefore, the boiler water temperature should be maintained in summer at about 10 ℃. The drain valve and outlet valve to prevent leakage. (3) periodic boiler feedwater, boiler pressure from holding 0.05MPa0.05MPa, preventing air from entering the drum. Second, the food factory boiler wet maintenance Wet maintenance is generally applicable to boiler maintenance, no more than a month of downtime. 1. After stopping the furnace, boiler water should be required to discharge time, scale, slag, dust should be clear and clean. 2. Close all running boiler completely isolated manholes, hand holes, valves. 3. acceptable basic protection with demineralized water solution, sodium hydroxide per ton of boiler water according to (OH) 8 kilograms 10 kilograms, or addition of sodium carbonate (NaC03) 20 kg, or sodium phosphate (Na2P03) 20 kg. 4. Use the prepared dedicated pump alkaline curing was poured into the boiler. 5. When the protective liquid completely injected, the water supply valve is opened, the injection qualified soft water boiler, overflowed until the air valve, and then closing the air valve and the water supply valve, opening a special circulation pump, the solution evenly mixed. 6. Throughout the maintenance and heated between 10 and outer surfaces 12 PH value should be kept dry by a micro furnace periodically, circulating pump periodically opened, the concentration of the solution is consistent, regular testing and replenishing solution and the solution. Ensure that the boiler water alkalinity. 7. Winter All landlords, take appropriate measures freezing.
Beijing New Energy Automobile Co., Ltd. is China's first to operate independently and gain new energy automobile production qualification of new energy auto companies, mainly engaged in new energy vehicles and key parts and components research and development, production, sales and service business segments, and the layout intelligent manufacturing, energy management, smart travel, Internet +, and other strategic emerging industries. In the new energy automobile manufacturing process, and a series of paint drying processes can not do without the help of hot water boiler. Due to the company before the device has reached less than the growing production needs, the introduction of the 2017 mid-tail electric company producing heating pressure hot water boiler (CEDR0.7--95 / 70-Ⅱ).
