Protection device Vacuum boiler Vacuum boiler is a kind of hot water boiler ，from the basic principles of vacuum boilers 1972 Zurich University of the invention。The vacuum boiler is mainly used for civil heating, concrete can be used in hotels, residential areas, commercial establishments and other occasions for heating, sanitary hot water heating The vacuum boiler is a vacuum environment to form a negative pressure inside the furnace body closed, filled with hot water in the body. By heating the combustion or other medium water, hot water is heated by steam, the steam condensing heat exchanger heating pipe in the water, the hot water supply. Vacuum boiler heat transformation Oil, natural gas, gas, electricity -> combustion (electrical conversion heat) -> heat medium water -> steam condensing heat exchanger after boiling -> Heat Exchanger -> Heat Conduction -> Water Vacuum boiler through the vacuum, formed a little air of low pressure environment, and then use the water at low pressure (less than atmospheric) boiling temperature to produce steam, condensation heat transfer by way of principle soda heat output of work. Vacuum heat medium water in the boiler is the result of oxygen, cleaning and other special treatment of high water, a charge the factory is completed, when used in a closed loop inside the unit (vaporization → condensation → vaporization), not increase, not decrease, in the unitYou do not need to supplement or replace the inner life. Advantage 1. there is no expansion of the vacuum boiler explosion, the risk of rupture, safe and reliable. 2. The use of a machine, can also provide a boiler for heating water, domestic hot water, pool heating. 3. The design life of more than 20 years, can be placed in the basement and the roof, the state authorities are not limited. 4. efficient and cost. 5. No scaling, corrosion and other phenomena. 6. boiler than the average small size. Modular and in parallel, more reasonable and effective operation of the boiler. Can be opened only when a willfully without nominal heat. 7. The high level of automation, building automation connection, unmanned management. Mainly for civilian use, such as hotels, residential, office, bath, schools, shopping malls and other places. Classification Vacuum boiler mainly classified by fuel, which can be divided into electrically heated vacuum boiler, oil boiler vacuum, vacuum gas boilers, coal-fired boilers and other vacuum.
