A new superalloy, developed by Haynes International and tested by a collaborative effort led by NETL, has received American Society of Mechanical Engineers (ASME) approval for use in the next generation of power plants that will operate with enhanced efficiency and produce fewer greenhouse gas emissions.
The ASME, whose code and standards are regarded as the world’s leading set of rules for the design of pressure equipment, approved the nickel-based superalloy for use in boilers, fired heaters, pressure vessels and other key components at conditions of up to 875 degrees Celsius (1,607 degrees Fahrenheit), which covers maximum anticipated operating conditions of Advanced Ultra-Supercritical (AUSC) plus carbon dioxide (CO2) capture power plants.
Across much of the U.S. and in more than 100 countries, the ASME code stamp is required for boiler and pressure vessel installations and is a mandatory requirement of many insurance companies.
