Commercial Vacuum Hot Water Boiler Manufacturers

Vacuum boiler principle. The vacuum hot water unit internally draws a vacuum chamber by vacuum pumping; after the boiler is started, the heat generated by the fuel combustion is transferred to the heat medium water in the heating surface, so that the heat medium water evaporates into a negative pressure steam under the negative pressure state in the furnace.

Tube heat exchanger -

Vacuum evaporating plants The boiler-heat exchanger is flow area of sheath 2-3 times higher than the flow area inside the pipes. Therefore, when the liquid is equal to the phase flow of heat transfer coefficients on the surface are low, which reduces the coefficient of thermal units. Device in sheath and pipe of exchanger increases the
