How to Properly Operate a Pressurized Gas Boiler

Boilers are widely used in various industries and are closely related to our food, clothing, housing, and transportation. As a high-temperature, high-pressure thermal energy device, pressure gas boilers are specialized equipment that is extensively employed. If not handled with care or operated incorrectly, they can easily lead to equipment damage and serious consequences. Many users have questions about how to properly operate pressure gas boilers; Zhongjie has specially prepared answers for you.

 

1. The boiler shall not exceed its pressure rating.

Since the pressure that a pressure-fired boiler can safely handle has been precisely determined through careful calculations, the boiler must not exceed a certain pressure range arbitrarily. As the thickness of the steel used in boilers operating at different pressures and the corresponding inspection requirements vary, failure to strictly adhere to these regulations could lead to serious consequences if the boiler is subjected to excessive pressure.

 



 

II. Strictly adhere to the boiler’s operational specifications.

Depending on the pressure level, gas boilers can be classified into high-pressure boilers and pressure boilers, and there are certain differences between the two. The key distinction is that the manufacturing quality and testing methods applicable to atmospheric-pressure boilers cannot be used for pressure boilers, which are directly connected to the atmosphere and always operate at zero pressure. Therefore, it is not permissible to convert a pressure gas boiler into an atmospheric-pressure boiler; otherwise, this could lead to serious consequences.

 

III. Boiler safety accessories are indispensable.

Pressure-bearing gas boilers are equipped not only with safety accessories such as water level gauges, pressure gauges, and safety valves, but also with water level alarms and overpressure alarms. These accessories and devices enable the pressure-bearing boiler to “communicate” with operators. Therefore, safety accessories for gas boilers are absolutely essential. By using these safety accessories, operators can promptly and accurately identify any abnormalities in the equipment, ensuring the normal operation of the gas boiler and preventing serious consequences such as equipment explosions. It is recommended to regularly clean the water level gauge daily to prevent blockages, check the pressure gauge and safety valve on schedule, and perform exhaust tests as required.
