    The steam drum is the primary interface between water and steam. In a coalfired plant, boiler feedwater passes through the economizer and into the drum where the steam separates from the feedwater and is drawn off to the superheater. In combined-cycle operations, a Heat Recovery Steam Generator (HRSG) serves the same purpose as a boiler.

    What Is A Steam Trap & How Does A Steam Trap Work?

    A steam trap is a device that removes condensate from a steam system. A typical steam system will have many steam traps – they are placed at 50-150’ intervals in straight pipe, after every heat exchanger (where the work gets done), and at every location where there is a change of elevation or pressure. What is the purpose of a steam trap?
