Flow path upgrade
The units in power plants which hae been operating for a long time may experience problems such as low automation, poor stability, and low efficiency due to the limitations of early technology. In this case, DTC deelops the third-generation flow path retrofit technology with the combination of the latest technology and the manufacturing experience of steam turbine. This technology is capable to reduce the unit heat consumption rate while keeping the current boiler's rated parameters and output unchanged. Turbine rated output can also be increased appropriately (depending on boiler eaporation and low acuum exhaust conditions). Through the upgrade, the unit efficiency can be increased by 1.5 ~ 4%.
