"Vacuum" refers to an automatic vacuum apparatus and the pressure inside the boiler is lower than the outside atmospheric pressure is low with water a low boiling point characteristic, rapid heating of the heat medium water, increase the heat transfer rate.

Fangkui Boiler aims to "warm the world", and we provide target customers worldwide with boiler equipment and service guidance to meet their needs. At present, we have provided boiler equipment and solutions for customers in more than 80 countries and regions, including Russia and Bangladesh, to promote the production efficiency of customer enterprises.

A safe and reliable good quality vacuum hot water boiler during operation, the pressure inside the artificially set within a range, so that the gas in the interior of a vacuum state, even if the failure causes problems because of the boiler, also outward risk of explosion will not occur. This design not only ensures the safety of electrical appliances, but also so as to avoid unnecessary losses and a series of troubles caused by lack of water Second, energy savings and stable performance of the vacuum hot water boiler in a vacuum state, effectively improving the thermal efficiency conversion. Three-pass boiler using the wet back design, a large amount of area to improve the radiation and convection heat transfer area, efforts to enhance energy boiler again. Use a vacuum hot water boiler not only to reduce the pressure on his own life, but also to achieve the concept of environmental protection, it would be to make a contribution to environmental protection. Third, easy to transport vacuum hot water boiler uses a modular design, not only high-performance heat exchanger, and the volume of the unit is small, more easily during transportation; boiler may also be employed combinations of several parallel-connected, the user according to their own needs, flexibility to adjust the number of operating boiler, to avoid waste of resources.

Directly affect the vacuum gas boiler energy consumption indicators of the country are a number of reasons to move coal to natural gas roaring blaze of glory, with vacuum gas boiler, greatly weakened contaminated with fine particles, the same time nitrogen oxides and other toxic gases obtained suppressed. Energy consumption index is a measure of normative matters vacuum gas boiler, we look back with a direct impact on a number of reasons vacuum gas boiler energy consumption indicators. By investigation personnel, vacuum gas heat loss generated in the boiler comprises two main parts: the air-fuel ratio combustion and flue gas emissions unreasonable thermal losses. Emission impaired heat loss should be modified in vacuo to rear of the boiler exhaust gas re-use latent heat setter, or better with a type of condensation recovery boiler. Unreasonable fuel ratio faults into: general gas ejector vacuum boiler burner selection, causing air-fuel ratio can not be adjusted automatically. Very many vacuum gas boiler automatic selection of strong non-stage burner, because of unreasonable fuel ratio initiator has the following aspects: the main air-fuel ratio unreasonable comprises two situations: when the atmospheric exceeded, the cool air will be excessively rich the action of heat, vacuum gas boiler initiation energy increase, decrease energy consumption indicator gas boiler in vacuo; when the atmospheric enough, will cause insufficient combustion, vacuum gas generating boiler decreased energy consumption indicator.
