The basic principle of the vacuum furnace and performance advantages

1.1 the principle of vacuum furnace and structure
Mainly by the furnace, smoke tube, heating coil and a chimney. Using the negative pressure of steam heat exchange technology, the runtime will be used as heat medium of the liquid level control between the smoke and fire tube and the heating coil, the pressure in the furnace is made by high temperature exhaust gas pressure, operation and control the negative pressure condition. Full combustion of fuel burner, heating tube and the fire heat pipe is passed to the pot shell intermediate medium water, boiling water is heated by the liquid into gas phase evaporation, water vapor gradually filled with gas phase space of the furnace body, because the coil is the heating medium and the tube wall temperature is lower than the steam temperature, so that the vapor in the outside wall of the condensing coil, and the heat transfer medium to coil. After the condensation water in gravity whereabouts backwater space. Cycling heat process was realized. To take the negative pressure of heating furnace operations, mainly considering the security issue, the normal pressure will cause the high temperature furnace flue gas leakage, heat loss increase, not only will cause the destruction of the stove itself and the harm to personal safety.
1.2 the advantages of vacuum furnace
(1) safe and reliable, energy saving water. Negative pressure, can be exempt from explosion hazard.
(2) the furnace combustion, the system is not easy to scale. Using pipe, corrugated pipe do itself as a thermal compensation device, with self-cleaning heat bilges cold shrink role, is not easy to scale.
(3) high thermal efficiency, environmental protection and energy saving. Adopts the design of positive pressure combustion type, ensure high efficiency heat transfer, fuel efficiency as high as more than 99%, compared with the traditional boiler, fuel can save about 17%; Low nitrogen oxide and carbon monoxide generation makes flue gas emissions clean, no pollution to the environment.
(4) the fuel adaptability is extensive, natural gas is a plus.
(5) the high degree of automation control, the user can on-demand configuration.
