How To Get The Best Boiler Installation - Which?

New regulations were introduced in 2017 to govern boiler installations in England. All new gas boilers installed in England, regardless of type, need to have an ErP efficiency of at least 92%. If time and temperature controls aren't already installed and working, any new boiler installation must include them.

What is a "pegging steam" in the HRSG deaerator

Apr 12, 2005 · If the dearator pressure drops faster than about 1 psi/sec, then the liquid to the BFP will boil in the downcomer, and cause cavitation in the BFP suction. Several startup events can cause the dearator pressure to drop, so to prevent that, there should be a backup supply of steam to peg

Deaerator - an overview | ScienceDirect Topics

This supplemental steam is known as pegging steam. In the case where the low-pressure integral deaerator is not used to export steam to a steam turbine, the pressure can be allowed to float upward and reduce the LP evaporator heat absorption when there is more heat available in the exhaust stream than is required to generate steam for deaeration.

Consulting - Specifying Engineer | Basics of boiler selection

Sep 15, 2017 · The required boiler feedwater must also be deaerated to remove excess oxygen and noncondensable gases prior to admittance into the boiler. This process requires the use of low-pressure steam, commonly referred to as pegging steam. If this steam is being supplied by the boiler, then the parasitic load needs to be accounted for during design.
