Vacuum hot water boilers are the main products promoted in the boiler market in recent years. Compared with conventional hot water boilers, there are many differences in structural design and operation.
When buying boilers, many people always have doubts about the type of boiler "vacuum boiler": they don't know what the concept of vacuum boiler is, whether it is suitable for their own enterprise or the production of Zhongcheng boilers, let me introduce to you: vacuum heat boiler What type of boiler is a water boiler?
Different from traditional industrial boilers, the internal pressure of vacuum boilers is lower than the external pressure, which is mainly designed to output hot water more efficiently. As the internal pressure decreases, the boiling point of water also decreases. This allows the water to boil quickly even at low temperatures. In addition, vacuum hot water boilers also have many advantages:
1. High efficiency:
Since the vacuum hot water boiler exchanges heat between steam and water, the entire heat exchange coil is surrounded by negative pressure saturated steam and is in the working state of the wet coil, and the heat exchange efficiency is much higher than that of water and water heat exchange. Therefore, the volume of the vacuum boiler is smaller and the efficiency is higher, which can better reflect its advantages for smaller installation sites. Moreover, because the steam and water exchange heat during operation, the preheating time of the boiler is shorter, and the operation cost is saved.
2. Safe and reliable
The vacuum hot water boiler always operates under negative pressure, and there is no danger of expansion and explosion, making it safer and more reliable than normal pressure boilers and pressure boilers.
3. Long service life
No scaling occurs inside the boiler, which increases the service life of the boiler, in general, it is 1.5 to 2 times the service life of the general boiler. In addition, the heat exchanger part of the vacuum boiler is made of stainless steel tube, which is corrosion-resistant and has a designed service life of more than 20 years.
