摘要

采用等效焓降法计算机组锅炉汽动引风机方案和电动引风机方案的煤耗差

并对电动和汽动引风机方案的投资回收年限

及其与煤价、电价的关系进行了分析

得出在不同电价和煤价影响下的回收年限。按标煤价格900元/t

电价0.43元/(kW·h)计算

仅需2.86年即可回收汽动引风机方案的全部投资。

Abstract

The equivalent enthalpy drop method was employed to calculate the coal consumption rate difference between boiler with steam-driven induced draft fan and that with motor-driven induced draft fan.Furthermore

the investment recovery periods of above two schemes under different electricity prices and coal prices was analyzed by an all-purpose economic evaluation method.The results show that

it needs 2.8years to recover the full cost on the basis of the standard coal price for 900yuan/t and the electricity price for 0.43yuan/(kW·h).
