Vacuum hot water boiler is a kind of boiler equipment that uses the characteristics of low-pressure and low-boiling water to quickly heat the sealed furnace filled with heating medium water to output high-temperature hot water. The boiling of hot water evaporates high-temperature water vapor, and the water vapor condenses on the heat transfer tube to heat the cold water in the heat transfer tube. Supply hot water. What are the characteristics of the vacuum hot water boiler when it is operated? Let Zhengzhou Fangkuai boiler manufacturer tell you the answer.
1. The inside of the vacuum hot water boiler is under negative pressure. If you follow the operating instructions, there will never be an explosion, and the safety is very good.
2. The internal design of the vacuum hot water boiler is reasonable, the bearing steel has high temperature and high separation, which can extend the service life to more than 2-3 times. The design life is up to 25 years.
3. The overall design of the vacuum hot water boiler is very scientific and reasonable, and the layout is compact. Compared with ordinary hot water boilers, the floor space is saved by about 50%. There is basically no requirement for the boiler house, and the infrastructure cost is very low.
4. The vacuum hot water boiler exchanges heat in the machine body. The operating efficiency of the whole machine is as high as 107%. It can provide 80℃ hot water within 2 to 3 minutes after startup, which greatly shortens the preheating period and reduces energy consumption.
5. The vacuum hot water boiler adopts automatic control, intelligent, unmanned or remote network control; the boiler has a built-in stainless steel heat exchanger, and the output water quality is free of any pollution.
6. The vacuum hot water boiler adopts the direct heating mode. Compared with indirect heating (boiler + external heat exchanger + circulating water pump + material + installation cost), it can save at least 30-40% of installation cost. In addition, the vacuum hot water boiler has high operating efficiency, fast heating, and good heat exchange, which can save fuel costs by 20-30%.
