commercial heavy oil fired vacuum hot water boiler
Vacuum hot water boiler internal body structure in a vacuum state of the commercial fired vacuum hot water boiler, by the combustion chamber (furnace), water, vacuum vapor chamber, heat exchanger, heat medium consisting of water or the like. Vacuum state within the body, from the outside air, a sealed state is formed. HTM furnace and covered with water in a sealed tube and within the body, by the pressure of the negative pressure in the steam chamber is maintained below atmospheric pressure, when the heat medium water confined in the inner combustion heating, boiling up immediately, generating heat medium water steam of the same temperature. Steam generated in the machine during the ascent, the contact surface of the heat exchanger is disposed in the negative pressure of the steam chamber, since the water temperature in the heat exchanger is lower than the steam temperature, steam condenses on the heat exchanger surface and release a large heat of vaporization , the water heating heat exchanger, the condensed water under the action of the policy back to the heat medium water again. Accordingly, the heat medium water in a closed continuous body with boiling evaporated = = = heat medium condensed water circulation. No need to supplement the condensed water, no air burning danger. Water heat exchanger is supplied to the user for heated sanitary hot water and air conditioning.
What are the characteristics of vacuum boilers?
Vacuum phase change boilers in the industry are usually referred to as vacuum boilers. Professional vacuum boilers form a negative pressure vacuum environment within the enclosed furnace body. There is no danger of expansion and explosion because a vacuum boiler creates a low-pressure environment with little air, and then uses water to boil at a low temperature to produce steam. As a result, it is now commonly used in higher elevations. Let's find out what the features of the vacuum boiler are.
1, the vacuum boiler will not corrode because the internal structure of the vacuum boiler is negative pressure vacuum state, so it is completely isolated from the atmospheric pressure, so the pump pumps configured by the various units of the boiler will continuously discharge the steam from the unit. It does not corrode the internal structure, so vacuum phase change boilers perform fairly well in terms of durability.
2, safety and reliability are different from ordinary atmospheric pressure boilers. Because vacuum boilers pump air out of the inner container to form a vacuum environment, the furnace body does not work under the vacuum body in the course of use and will not be expanded by heat. It is not a pressure vessel, so there is no risk of explosion. At the same time, if the pressure increases due to faults or other perceived factors, the vacuum pressure switch automatically cuts off the power supply, so vacuum boilers are more reliable than other types of boilers in terms of safety.
Since I began preparations for the 2018 ASME certification program, and at the beginning of the project preparation work since January this year, the project has entered a crucial stage of the implementation. Ms. Jiang Lianju quality system under warranty division led to ASME certification were careful overall planning work to develop a detailed plan of the evidence, and careful organization departments to participate in the work of the various stages of implementation.
Oil and gas fuel introduction
There are several series of oil and gas boilers produced by ZG boiler, wns oil and gas boiler series, szs oil and gas boiler series, vacuum hot water boilers and fuel gas power station boilers. ZG boiler 's 70-year manufacturing history has made ZG boiler a rich boiler technology achievement. ZG boiler 's boiler series products are developing rapidly, and they are traced to more than 80 countries and regions around the world, and are gradually entering every corner of the world.
