Abstract

Steam turbine low-pressure cylinder exhaust channel optimization reform

is to install the curve-shaped diversion device on the steam turbine low-pressure cylinder

so that the flow field of the steam turbine low-pressure cylinder into the condenser cooling tube is reasonable

the heat load of the condenser heat exchanger is even

the heat transfer efficiency is increased

the exhaust pressure is lowered to increase the unit vacuum

The purpose of increasing unit economy.
