HRSG super long boiler tube

What is HRSG (Heat Recovery Steam Generator) boiler tubes?

HRSG (Heat Recovery Steam Generator) boiler tubes are an important component of a combined cycle power plant. These tubes are responsible for transferring heat from the exhaust gases of a gas turbine to generate steam, which can be used to produce additional power or for other industrial processes.

While HRSG boiler tubes come in various lengths depending on the specific design and requirements of the power plant, they are generally not considered super long compared to other types of boiler tubes. The length of HRSG boiler tubes can vary based on factors such as the size of the power plant, the desired efficiency, and the manufacturers specifications.

The main steel grades used for HRSG (Heat Recovery Steam Generator) boiler tubes 

1. Carbon Steel: Carbon steel grades such as ASTM A210 Gr. A1 and ASTM A192 are often used for HRSG boiler tubes. These grades provide good mechanical properties and are suitable for moderate operating temperatures.

2. Alloy Steel: Alloy steel grades offer enhanced strength, high-temperature resistance, and improved corrosion resistance compared to carbon steel. Common alloy steel grades used for HRSG boiler tubes include ASTM A213 T11, T22, and T91.

3. Stainless Steel: Stainless steel grades are used when corrosion resistance is a critical requirement. Grades such as ASTM A213 TP304, TP316, and TP321 are commonly used for HRSG boiler tubes in corrosive environments.
