Biomass boiler can use overhead water tank constant pressure method to constant pressure

　　Constant pressure method of biomass boiler

　　The constant pressure method in the biomass boiler heating system: In the high-temperature hot water supply system, because the water temperature is higher than the saturation temperature of water under normal pressure, the pressure in the system should be higher than the saturation pressure of the corresponding water supply temperature, so as to allow Hot water vaporizes and water shock occurs. Water is a non-compressible fluid, and water heating will shrink in volume. If the pressure cannot be stabilized, the equipment in the heating system will also be destroyed. Therefore, in order to prevent vaporization and shrinkage, the high-temperature hot water system must stabilize the pressure in the system, which is the constant pressure. There are several ways of constant pressure for hot water heating system:

　　Using elevated water tank constant pressure method

　　The fixed pressure point of this method is set on the main line of the hot water pump inlet or return water, and an elevated water tank is installed. The structure is simple, the work is stable and reliable, and the system pressure and the system network's overflow and refill request can be stabilized. In this kind of system, the water tank device should prevent the high points in the system from vaporizing. Therefore, the location of the device is higher. This constant pressure method is suitable for low-temperature water heating systems with a small heating range.
