| Abstract: | a Anhui power plant first phase project is two 300MW class power units,the unit steam turbine is aging,thermal efficiency at generator terminals is increased,so they need to make the transformation,improve efficiency,through research conducted 1# turbine steam seal reformation of big machine,high pressure cylinder part adopts the Brandon steam seal,and low pressure cylinder adopts the honeycomb steam seal.After the transformation of coal consumption decrease in 3.12g/kWh,obvious energy saving effect. |
| Keywords: | the Brandon steam seal the honeycomb steam seal transformation |
