| Abstract: | The N300-16.7/538/538 turbine made by Shanghai Turbine Corporation is researched, and the thermal system after canceling the deaerator is analyzed. If the common deaerator system is replaced by the compound condensing water vacuum deaerator system, the key factor which influence the thermal economy of the unit is the exhaust steam pressure of the small turbine, so it must be optimized which is introduced in this article. And the thermal economy of the unit before and after retrofit is compared. The result of the research make clear that after canceling the deaerator the thermal economy of the unit is improved greatly, the coal consumption is decreased. |
