The HRSG can make steam directly from the hot turbine exhaust, or burn additional fuel to make more steam to satisfy campus heat loads and keep the existing boilers off-line. A 500-kW steam turbine is also installed as part of the project, generating electricity by taking the high-pressure steam produced by the HRSG and boilers and reducing the pressure for campus distribution.

2015/3/17 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
