Economic and Environmental Analysis for Steam-Driven Induced Draft Fans of 1036MW Ultra Supercritical Units

Abstract:

Concerning the steam induced draft fan renovation tendency in large coal-fired power plants, the economic and environmental benefit are analysed for certain 1036MW ultra supercritical units. Under the same generator output, despite the power generation coal consumption for the scheme with steam induced draft fan coal increased, the auxiliary power reduced significantly which results in roughly RMB 10,657 thousands yuan economic saving every year with about 1.9 years payback period of investment. Due to the power supply coal consumption saving, the annual amount of pollutants reduction of CO₂, SO₂, NO₂ and dust are 4440.867, 16.462, 45.514 and 220.829t, respectively.
