In industrial boiler applications, pressure gas boiler systems are categorized based on their working pressure levels. These classifications include low-pressure, medium-pressure, sub-high-pressure, and high-pressure boilers, each suited for specific operational needs. Low-pressure gas boilers operate with a working pressure below 1.25 MPa, making them ideal for light industrial processes such as textile washing or food processing. Medium-pressure boilers work under 3.8 MPa and are commonly used in industries requiring moderate steam output. Sub-high-pressure boilers are designed for a pressure of 5.3 MPa, serving manufacturing lines with higher thermal demand. High-pressure gas boilers, operating at 9.8 MPa, are typically found in heavy industrial facilities. Understanding the classification of a pressure gas boiler is crucial for selecting the right equipment for efficient and safe operations.
