Customized Acid Resistant Boiler Economizer Parts

Economizers are tube heat exchangers located in the top section of a boiler. They raise the feedwater temperature to slightly below saturation temperature. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. Economizers preheat the cold water used to fill water wall panels.

Economizers consist of parallel-mounted steel tubes, butt welded and bent, and subject to the highest pressures and lowest temperatures. They need good mechanical strength at metal temperatures up to 380 °C (and/or steam temperatures up to 330 °C). Accordingly, they are usually made of carbon steel.

1. Strength calculation report with applied materials information;
2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;
3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler;
4. Hydraulic test report: ensure the standard working pressure and safety
