Options for Improving the Efficiency of Heat Recovery

In a conventional steam generator such as a package boiler, the exit gas temperature is independent of steam pressure. With say a 230 F feed water temperature, an exit gas temperature of about 300 F can be easily achieved using an economizer as the heat recovery equipment.

Applying ASME Boiler Code to Steam Generation

(Page 1) The main focus of the ASME boiler code is on power boilers, rather than on petroleum refinery or petrochemical heaters, so definitions are sometimes not clear. Furthermore, it can be difficult to define which authority has jurisdiction over steam generation systems in the CPI. Even in the U.S. This article provides guidance on the requirements for stamping within the ASME code and
