Calculating Pollution Equivalent of Electric Heating with Heat Storage Technology Accommodating Wind Based on LCA

Abstract

Electric heating with heat storage technology can effectively reduce the abandoned wind of wind farms located in north china during the winter, improving the consumptive capacity of wind power. Considering the poor economy and singleness of electric heating with heat storage technology, life cycle assessment method is applied to analyze each stage of electric heating boiler with heat storage technology, including production, transportation, construction, operation and dismantling scrap. Meanwhile, the pollution emissions of each stage are calculated and compared with the cogeneration of heat and power in order to analyze its superiority and expansibility. The research result shows that the electric heating with heat storage technology consuming abandoned wind will reach a obviously lower pollutant discharge level than cogeneration heating mode. Therefore, from the point of environmental protection, electric heating with heat storage technology has extensive popularization significance in north China where abandoned wind phenomenon is serious.
