What is Steel Pipe Heat Number ? Heat Number Definition A heat number is a unique identifying code a technician stamps on a piece of metal to provide information about its origins. Metal plate and pipes are most likely to bear this number, and in some cases, the law requires its use on metal products.
Waste heat streams can be used to generate power in what is called bottoming cycle CHP—another term for WHP.1 In this configuration, fuel is first used to provide thermal energy in an industrial process, such as a furnace, and the waste heat from that process is then used to generate power. The key advantage of WHP systems is that
