What is a "pegging steam" in the HRSG deaerator

Apr 12, 2005 · 3 psi is an absolute minimum, but it depends boiler to boiler. You also can't have rapid changes in the deaerator pressure. To make up for any shortfalls in heat to the LP system you bring in a more reliable source of steam - i.e. from the HP steam system (or IP, if you have an IP drum). That's pegging steam. It's not limited to HRSG's. A
