针对某电厂2×135 MW纯凝汽式机组改成供热机组问题，从投资大小、改造难度、对发电量的影响等方面对2种改造方案进行了分析，最终选择了风险小、成本低的改造方案。应用结果表明：机组实现了热电联产，提高发电厂循环热效率20%；1台机组节约燃煤83040 t/a，节约燃料费用1992.96万元/a；减少灰渣排量20760 t/a，减少CO2排放量8367 m3/a，减少SO2排放量85 m3/a，节能环保效益显著。
針對某電廠2×135 MW純凝汽式機組改成供熱機組問題，從投資大小、改造難度、對髮電量的影響等方麵對2種改造方案進行瞭分析，最終選擇瞭風險小、成本低的改造方案。應用結果錶明：機組實現瞭熱電聯產，提高髮電廠循環熱效率20%；1檯機組節約燃煤83040 t/a，節約燃料費用1992.96萬元/a；減少灰渣排量20760 t/a，減少CO2排放量8367 m3/a，減少SO2排放量85 m3/a，節能環保效益顯著。
침대모전엄2×135 MW순응기식궤조개성공열궤조문제，종투자대소、개조난도、대발전량적영향등방면대2충개조방안진행료분석，최종선택료풍험소、성본저적개조방안。응용결과표명：궤조실현료열전련산，제고발전엄순배열효솔20%；1태궤조절약연매83040 t/a，절약연료비용1992.96만원/a；감소회사배량20760 t/a，감소CO2배방량8367 m3/a，감소SO2배방량85 m3/a，절능배보효익현저。
Aiming at the problem of 2í135 MW condensing generating units changed into heating supply units in a power plant,analyzes 2 kinds of retrofit schemes from the size of the investment, the transformation difficulty and the impact on generated capacity,finally selects the scheme with small risk and low modification cost. The application result shows that the units realize cogeneration, circulating heat efficiency increase 20%;1 unit save coal of 83 040 t/a ,save fuel costs of 1992.96í104 yuan /a,reduce ash emissions of 20 760 t/a,reduce CO2 emissions of 8 367 m3/a and SO2 emissions of 85 m3/a,the benefits of energy saving and environmental protection are prominent.
