What is a pressure-bearing hot water boiler?

18 Nov 2022

Hot water boiler is a kind of thermal equipment that uses natural gas, oil and biomass as fuel to heat water to the rated temperature. It is widely used for heating, bathing and domestic hot water in hotels, schools, hotels, communities and other enterprises and institutions. Generally, pressurized hot water boiler is widely used, so what does pressure-bearing hot water boiler mean?

 

In a pressure-bearing hot water boiler, the meaning of pressure is that the internal pressure of the boiler is higher than the atmospheric pressure from a professional point of view. Moreover, in the standard of Regulations on Safety Supervision of Special Equipment, it refers to the hot water boiler whose internal gauge pressure is greater than 0.1MPa. In addition, what we need to know is that the boiler pressure is maintained by pressure water tank or high-level water tank, not by constant pressure components.

 

The principle of pressure-bearing hot water boiler is that after water enters the boiler, the heating surface of the boiler transfers the absorbed heat to the water supply, so that the water is heated into hot water with a certain temperature and pressure, which is led out and transported to the heat exchange station for heat exchange, and the boiler return water is transported to the inlet of the circulating water pump through the return pipe.

 

The pressure boiler is always full of water during operation, so there is no water level gauge, but a pressure gauge, safety valve and thermometer must be installed. The circulating water pump of the heating system of the pressure-bearing hot water boiler generally adopts the fresh water pump, which not only needs to overcome the circulating resistance of the system, but also needs to maintain a certain pressure of the boiler to ensure that the hot water does not vaporize at high temperature. The pressurized hot water boiler can supply both low-temperature water and high-temperature hot water.
