One. Working principle of gas vacuum hot water boiler:
Two. 1.1.Vacuum hot water boiler is a heat transfer equipment that uses the phase change of heat medium water for heat exchange process. The heat released by fuel combustion is absorbed by the thermal medium water, and when the temperature rises to the saturation temperature in a certain vacuum state, it evaporates into saturated steam to complete the first phase transformation process. The resulting condensate flows into the evaporation chamber to continue to absorb heat and complete the phase change cycle.
1.2.The substructure of a vacuum hot water boiler consists of a combustion chamber and a bundle of heat transfer tubes. The upper part is a vacuum chamber.
1.3.A U-shaped tubular heat exchanger is inserted into the vacuum chamber, and the air extraction unit is connected to the outside of the vacuum chamber to keep the vacuum chamber stable at all times, and the non-condensable gas in the vacuum chamber is pumped out, so as to improve the heat exchange efficiency of the U-shaped heat exchanger.
Two. Performance characteristics of gas vacuum hot water boiler:
2.1.High efficiency and energy saving: Using high-efficiency vacuum hot water boiler technology, the boiler operates in a vacuum state, the boiling point is low, and the latent heat of vaporization is used for condensation heat exchange, which effectively improves the thermal efficiency.
2.2.Good heat exchange performance: the three-way design is adopted, and the waste heat ** device is installed in the flue path at the tail of the boiler, which fully improves the energy utilization rate, and the thermal efficiency of the boiler is as high as 98%.
2.3.Negative pressure operation of the unit: safe and reliable vacuum operation of the unit, the heat medium is always in a vacuum state, and there is no danger of expansion and high quality. The furnace is equipped with sufficient amount of hot water, and there is absolutely no danger of dry boiling. It is equipped with multiple automatic protection devices, which has the safety that other boilers cannot match.
2.4.No corrosion, no fouling, long service life: The heat exchanger is made of stainless steel, which allows the one-time injection of heat medium to operate in a closed state. The stainless steel material is non-corrosive and non-susceptible to fouling at high temperatures, making its service life nearly twice as long as that of ordinary boilers, up to 20 years.
2.5.Abundant models: There are vertical, horizontal, oil, gas, water pipe, smoke pipe and other models, which can be freely selected.
The heat exchanger is separated from the header. The load of heating water and clean hot water can be switched at any time according to the need, which can fully meet the different requirements of users for heating water and clean hot water in use, and ensure that the clean hot water is clean and stable.
2.6.Small size and easy installation: Modular design, high-performance heat exchange components, and small unit size make the product easy to transport and install. In a small space, multiple units can be used in parallel.
2.7.Distinctive environmental protection functions: high-performance burner, flame-back structure design, sufficient fuel combustion, and various environmental protection indicators meet the emission standards of national tourist areas.
2.8.Running under normal pressure eliminates complicated approval procedures: The unit runs under vacuum, which eliminates the installation inspection and approval of pressure-bearing equipment. There is no need for annual review, and operators do not need to hold a certificate.
2.9.Intelligent control: touch screen display, virtual buttons, Chinese and graphic display system conditions. **Automatic fault diagnosis in the operating state, fully automatic operation and manual operation can be used and used to achieve man-machine dialogue.
