The electric heating tube of the electric vacuum boiler never saves dirt and can be operated efficiently all year round with a thermal efficiency greater than 99%. Due to the continuous increase in scale of the electric heating tube, the thermal efficiency of the atmospheric pressure boiler is decreasing year by year, and the operating cost is increasing year by year.
Atmospheric pressure boilers need to be equipped with primary circulation pumps, heat exchangers, primary circulation tubes, etc., which have high heat loss.
Atmospheric pressure boilers are supplied with external heat, and there is a heat exchange loss, and the heat loss is more than 15%.
The electric vacuum boiler is operated under negative pressure, and there will be no blasting accidents, and it is very safe. According to the document No. 288 of the National Quality Inspection Bureau [2002], the electric vacuum boiler does not need to be registered and inspected by the quality and technical supervision part. There is a danger of blasting for the atmospheric pressure boiler. The top of the furnace body must be provided with an opening or receiving directly to the atmosphere, and to ensure that the opening or receiving is unblocked, it must be registered and inspected by the quality and technical supervision department.
The electric vacuum boiler operates in vacuum, the electric heating tube never scales, and the life span reaches more than 20 years (semi-permanent). The accessories of the electric vacuum boiler are also relatively simple, direct hot water supply, high efficiency, and no scaling. The fouling of the electric heating tube of the atmospheric pressure boiler continues to occur, the thermal efficiency is decreasing year by year, and the life span is generally about 8 to 10 years.
The electric vacuum boiler has multiple functions, and can provide heating water, daily hot water, and swimming pool heating at the same time. The designed life span is more than 20 years, and it can be placed in the basement and the roof of the building. The relevant part of the state is not restricted. High efficiency and low cost. No fouling, corrosion, etc. It is smaller than a general boiler. It can be modularized in parallel to operate the boiler more effectively and reasonably. When the rated heat is not required, only one of them can be turned on.
Electric vacuum boilers are gradually being accepted by everyone, mainly for civilian use, such as hotels, residences, office buildings, bathing centers, campuses, shopping malls and other local areas.
