So what is the principle of vacuum boiler? Small horn, let me introduce you.
The reason why vacuum boilers have incomparable advantages over industrial boilers in the past lies in their scientific principles.
It works according to the principle of vacuum phase change and can be used for heating and supplying hot water. When the vacuum degree is less than or equal to 0.02MP, the boiler is heated, continuously absorbed by the heating surface in the boiler, and gasified into steam. Steam rises to the upper part of the drum, condenses into water and then returns. At the same time, the water flowing in the condensed heating surface pipeline continuously takes heat out of the boiler for users to use, and the above process is repeated.
With this working principle, bad phenomena such as cracks, blisters, combustion deformation and explosion accidents are not easy to occur in morale, and water treatment equipment such as soft water and oxygen removal is not needed, which saves equipment and simplifies operation. Moreover, the horizontal boiler increases the heating area and greatly improves the thermal efficiency.
Conditions for effective and normal operation of boiler:
1, the fuel burns well.
2. Reasonable control of air volume
3. Efficient heat transfer mode
4. Firefighters' strict operating skills
Advantages of vacuum boiler:
1. The vacuum boiler is safe and reliable, and there is no danger of expansion, explosion and rupture.
2. One machine has multiple functions, and one boiler can provide heating water, domestic hot water and swimming pool heating at the same time.
3. The design life is more than 20 years, and it can be placed in the basement or on the roof, which is not restricted by the relevant state departments.
4. High efficiency and low cost.
5. No scaling and corrosion.
6. It is smaller than an ordinary boiler. Modular parallel arrangement can be carried out to make boiler operation more effective and reasonable. When the rated heat is not needed, only one of them can be opened.
7. High degree of automation, building automatic connection, unmanned management. Even if someone guards, the guards don't need to have an operation certificate. Simple training is enough.
Matters needing attention of vacuum boiler:
1. Before each operation of the boiler, check whether the gas pressure of the boiler is normal. Generally, the static pressure is required to be around 8 kPa, and only 6 kPa can maintain a small fire. If the fire is operated at this time, it may be extinguished due to insufficient pressure.
2. If everything is normal, first run the water pump, observe the water pressure and the sound of the water pump, and then turn on the boiler control power supply after confirming that it works normally. Never turn off the vacuum pump.
3. Pay attention to the gas pressure when setting parameters. If the gas pressure is lower than 6 kPa, it means that there is only hope of small fire operation, so the flame transition temperature should be as low as possible, so that it can only run small fire.
4. In addition to the temperature requirements, the size of the boiler should also match the load. Generally, a small fire boiler can be used when air conditioning is used alone for insulation and hot water is heated regularly. When the air conditioner uses hot water at the same time, but the temperature of the air conditioner basically meets the requirements, a boiler can be guaranteed with great firepower. When both must be heated at the same time, two boilers should be operated by fire.
The invention of vacuum boiler has brought us great convenience, and it needs relevant employees to make better use of it, create greater convenience for our life and make industry and environment more integrated.
