What is the normal pressure range of hot water boiler?

06 Aug 2021

Hot-water boiler is a kind of thermal equipment that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. According to different fuels, hot water boilers can be divided into gas-fired hot water boilers, oil-fired hot water boilers, biomass-fired hot water boilers, and coal-fired hot water boilers. How to choose hot water boiler? We will focus on the heating, pressure and thermal efficiency of hot water boiler.

 

At present, due to the rapid economic development, it has brought great pressure to the environment. Therefore, in order to promote the energy conservation and emission reduction of the heating industry, the state advocates the use of oil-fired and gas-fired hot-water boilers as the main heating equipment. There are WNS series and SZS series of oil-fired and gas-fired hot water boilers produced by ZOZEN Boiler. WNS series hot water boilers have rated capacity of 0.7-14mw and pressure of 0.7-1.25Mpa; The rated capacity of SZS series hot water boilers is 7-116 MW, and the pressure of hot water boilers is 1-1.6 MPa.

 

However, it is very difficult to lay natural gas pipelines due to the terrain restrictions in some places, so biomass hot water boiler is also a good choice for environmental protection heating equipment. There are SZL series, DZL series, DHL series hot water boilers in ZOZEN Boiler. The rated capacity of SZL series hot water boilers is 2.8-29 MW, and the pressure is 1-1.25 MPa; the rated capacity of DZL series hot water boilers is 14-70 MW with the pressure ranging from 1 to 1.6 MPa; the rated capacity of DHL series hot water boilers is 29-116 MW, and the pressure is 1.25-1.6 MPa.
