What factors are generally related to the gas supply pressure of boilers?

16 Dec 2022

The change of heating pressure of natural gas will affect the normal operation of the boiler, resulting in anoxic combustion, deflagration, peroxide combustion, tempering and other phenomena. Then, what factors are generally related to the gas supply pressure of natural gas boilers, and how much should it be?

 

Gas supply pressure of boiler

The natural gas supply pressure of the boiler is mainly related to the tonnage of the boiler, and its general principle is:

If it is a gas boiler with a capacity of less than 3 tons, the gas pressure is 8-12—18kpa, or 12-18 kPa when it is between 3 and 8 tons. If it is more than 8 tons, it is 18-25 kPa. However, it should be noted that the gas supply pressure of the natural gas boiler here is static pressure, and if it is dynamic pressure, it is smaller than static pressure. Therefore, its specific value is lower.

 

How much and how to adjust the gas supply pressure of the specific natural gas boiler is mainly based on the system configuration of the original boiler manufacturer. You can also check the burner manual.

 

It is worth noting that, under normal circumstances, the pressure of the gas pipe network in the city is medium pressure, so the gas source cannot be directly supplied to the boiler, otherwise it will cause excessive pressure fluctuation or high pressure. Therefore, in the process of gas supply, a pressure regulator must be set to adjust the pressure in the pipeline before it can be supplied to the boiler for safe use. The boiler room gas should be supplied by laying a special pipeline from the urban medium-pressure gas supply supervisor, and it should be used after pressure regulation and measurement.
