【Abstract】 Considering the special features of heating in Heilongjiang, a highly cold area, the modes of electric heating and the special features of electric boilers are discussed. It is concluded from the technical and e-conomic analysis of the electric storage hot water system and the coal - fuelled boilers under Suihua electric power bureau, and the comparison of investments that the efficiency of electric boilers are much higher than that of coal - fuelled boilers , and the operating cost of electric boilers can be reduced through use of electricity at valleys and intermittent operations.更多还原
