摘要


為了達到提高能源使用效率及減碳之目的,以生質能汽電共生系統取代以燃燒化石燃料之發電產汽系統是值得推展的。本文分別簡介生質能及生質能蒸汽系統,評估生質能汽電共生在經濟面之可行性,並介紹平衡蒸汽供需落差之緩衝技術。由評估結果可知,以生質能汽電共生系統搭配雙效式冰水機,可以穩定供應電力並滿足製程對蒸汽的變動需求,也可將過剩之蒸汽轉為冰水,以減少空調用電,進而達到平緩電力負載之目的。由評估結果可知該系統投資之回收年限約為2年半。

In order to improve the energy efficiency and reduce the carbon dioxide emission of conventional fossil-fuel based power plant and boiler system, it is suggested that replacing the conventional system by biomass-based cogeneration systems for generating electricity and producing steam. The biomass and biomass boiler system were introduced in this article, and the economic feasibility of biomass-based cogeneration systems was also evaluated in this article. In addition, the steam compression system was introduced in this article, too. From the result of evaluation, the combination of biomass-based cogeneration and double-effect absorption chiller was suggested for providing stable electricity and steam for factories, and the steam that was not used by factories could be used by absorption chiller for producing the ice water. Hence, the electricity used by air conditioning system can be reduced, and the loading of power system can be reduced too. From the economic evaluation, the system payback period is about two and a half years.
