Boiler Pressure - an overview | ScienceDirect Topics

To minimize corrosion, erosion, and scaling in the boiler pressure parts and the steam turbine, it is important to keep dissolved solids and dissolved gases in the steam to a minimum. In a subcritical plant, dissolved solids are controlled via the boiler drum blowdown.

Hence, it is necessary to maintain the high-pressure turbine (HPT), intermediate-pressure turbine (IPT), and low-pressure turbine (LPT) differential expansions within the predetermined limits. An increase in differential expansion may be caused by too fast a change in inlet steam temperature or due to too rapid change in steam flow to the turbine.

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.

2017-9-22 · generation, steam turbine generators normally generate elec tricity as a byproduct of heat (steam) generation. A steam turbine is captive to a separate heat source and does not directly convert fuel to electric energy. The energy is transferred from the boiler to the turbine through high pressure steam that powers the turbine and generator.
