Natural gas vacuum phase change boiler

Product introduction:

The gas-water heat exchanger is used in the natural gas vacuum phase-change boiler, and its heat exchange efficiency is much higher than the water-water heat exchanger of the atmospheric pressure boiler by using the principle of phase change. As the whole unit operates under vacuum, the explosion hazard is completely avoided. Compared with traditional hot water boilers, this unit has unparalleled ease of operation. It is used to provide heating and sanitary hot water in various occasions such as hotels, offices, commercial and residential buildings.

Natural gas vacuum phase change boiler

Product introduction

The whole structure of the natural gas vacuum phase change boiler is a negative pressure hot water unit. The unit is equipped with burner and a smoke pipe. The unit uses natural gas to burn in the furnace through a burner, and the heat generated by the combustion heats the heat medium water. The air inside has been vacuum out before commissioning, and the machine is in a vacuum status. The heat medium water is heated to about 30and then evaporate in a vacuum state. The steam heat the hot water flowing in the heat transfer tube to provide it to the outside world hot water or sanitary hot water or for heating.
