Vacuum hot water boiler hot water boiler Vacuum Products Products vacuum hot water boiler works in the standard state, the vacuum boiler -76CMHG. After starting the boiler, fuel combustion heat is transferred to the heat medium heating surface of the water, the heat medium water is evaporated in heat exchange between the steam, the heat exchanger increase the vacuum chamber at a negative pressure within the furnace, condensate reflux of water to the furnace, boiler water using the steam phase change heat transfer process interact to achieve, through the phase change of the boiler water, water vapor condensation and evaporation furnace transfer latent heat boiler water to achieve the heat transfer process. Meanwhile, if the working medium of the heat exchanger, using the difference in heating temperature and the flow rate output with special requirements, can be specially designed according to the needs of users, the quality can be delivered on time. Heat exchanger, and the water distributor flange can be designed and manufactured of stainless steel for heat strong corrosive media. For larger heating case, a plurality of parallel operation may be performed, better results than the single-unit operation, better energy saving. The machine is running, a multi-purpose machine, while the need to provide different occasions, no need to install. Vacuum hot water boiler during operation, the internal pressure of the furnace in a vacuum state is always the -15cmHg-76cmHg. Even if the U-shaped heat exchanger leakage due to external pressure, or the operational failure can not exceed the external atmospheric pressure, the controller, the water temperature control, superheat and the vacuum pressure switch will automatically switch off the power. When the pressure reaches 0.025MPa, the safety valve will open automatically to withstand the discharge pressure.

what do you know about vacuum hot water boilers?

1. What is a vacuum hot water boiler? Answer: so-called vacuum hot water boiler, also called vacuum phase change hot water boiler. When the boiler is working normally, the inner medium pressure of the boiler is lower than the atmospheric pressure, and the cold water is heated by phase change heat. Vacuum sealing inside the body of vacuum hot water boiler, negative pressure combustion of heat medium water, steam exchange between steam and heat exchanger, high heat efficiency, one-time treatment and perfusion of heat medium water in factory, no need to replenish water in operation. The unique design of vacuum hot water boiler has formed the characteristics of safety, stability and so on.

2. The composition and structure principle of vacuum Hot Water Boiler? Answer: the furnace body of a vacuum hot water boiler is divided into two parts: the upper part is a vacuum chamber (negative pressure steam chamber), and a tubular steam-water heat exchanger is installed in the space to heat the circulating water flowing through the heat exchanger. Operation principle: during the operation of vacuum hot water boiler, the heat medium water inside the furnace under negative pressure of vacuum absorbs the heat energy released from fuel combustion, boiling vaporizes into low temperature steam, and the low temperature steam rises to meet the system circulating water in stainless steel heat exchanger. Heating circulating water to the user for heating or sanitary hot water. The water vapor itself is cooled and condensed into droplets falling onto the surface of the heat medium and then heated again, thus completing the whole cycle. Heat medium water The cycle of "boiling = evaporation = condensation = heat medium water" is constantly carried out in the enclosed body, so there is no need to replenish condensate water and there is no danger of empty burning. The condensation heat transfer coefficient of steam-water condensation in vacuum hot water boiler is the highest in all heat transfer conditions.

3. What is a vacuum? Answer: vacuum state does not mean absolute pressure is zero, as long as lower than external pressure, can be called "vacuum". For example: vacuum boiler operating inside the shell is debugged as vacuum and maintained between-375pxHg--76mmHg.

4. What is vacuum? A: vacuum refers to the degree of gas rarity in vacuum, usually expressed as "high vacuum" and "low vacuum". High vacuum means good vacuum, low vacuum means poor vacuum. The value of vacuum degree indicates that the actual value of system pressure is lower than that of atmospheric pressure, that is, vacuum degree = atmospheric pressure-absolute pressure. International standard unit of vacuum: Pa (Pa).

5. Why is heat medium water in vacuum hot water boiler heated in vacuum? Answer: the boiling temperature of water is different under different pressures. Under an atmospheric pressure (0.1Mpa), the boiling temperature of water is 100 ℃, while the boiling temperature of water is 4 ℃ under 0.8Kpa pressure. The vacuum hot water boiler works within the pressure range of vacuum degree 2.67Kpa~66.6 Kpa, and the corresponding saturation temperature is 15 ℃ ~ 85 ℃. Therefore, in vacuum, heat medium water is easy to boil and vaporize.

6. The origin of vacuum hot water boiler? A: the basic principle of vacuum hot water boiler was born in 1972 at Zurich University of Technology. In 1975, Japan's TAKUMA Company developed a vacuum hot water boiler on the basis of the principle, which was patented for invention, and was gradually popularized all over the world. This technology has been developed and developed by Korean enterprises, and South Korean TAKUMA, has appeared one after another.

Oil-fired boilers generally burn diesel oil, as well as boiler professional fuel oil, black oil and so on. But fuel oil is now being turned to fuel because of rising diesel prices and supply problems. (1) crude oil: crude oil that is extracted from the ground and dewatered and not refined. Crude oil can be refined to produce a variety of oil and other products, directly as fuel is extremely unfair. (2) heavy oil: it is composed of cracked heavy oil, vacuum heavy oil, normal pressure heavy oil or wax oil according to different proportions, with certain grades and quality standards. (3) residual oil: the residue in the petroleum refining process, which can be supplied directly to the boiler as fuel without treatment, and is habitually supplied to the boiler as fuel. Called residual oil or residual oil. Heavy oil and residue oil are the main kinds of liquid fuel for power generation. The common characteristics are: higher relative density and viscosity, higher boiling point and flash point, and less volatilization. (4) Diesel fuel: diesel fuel is the fuel of diesel engine, and it is extremely uneconomical as boiler fuel. Diesel oil is generally used as ignition oil for pulverized coal boilers and for stable combustion at low load.
