摘要
本研究探討都市固體廢棄物(municipal solid waste, MSW)及其能源管理策略,將MSW焚化產生之能量轉製電力,發展「廢棄物轉製能源(waste to energy, WTE)」技術,其為備受認可之高應用性能源回收及發電技術。臺灣因土地與自然資源有限,現行運轉中24座大型WTE焚化廠,其建設密度比(WTE焚化廠/土地面積)位居世界最高。前述24座大型WTE焚化廠總設計發電裝置容量為558.5百萬瓦,預期可產生每年167百萬美金之經濟效益(能源效率100%狀態下)。臺灣產生之MSW兼具高熱值(1,873 kcal/kg)且低含水率(53.4%)之特性,其有利於直接以焚化處理,發展WTE再生能源技術。臺灣每年約有6.5百萬噸之MSW焚化產生再生能源,並可有效減少MSW體積。本研究引用歐盟R1公式計算國內24座大型WTE焚化廠之能源效率,發現焚化廠之設計發電量、發電裝置容量及MSW之低位發熱量(low heating value, LHV)為影響WTE焚化廠能源效率之重要參數。本研究結果可應用於改善國內現行WTE焚化廠之能源效率提升,並適用其他國家WTE焚化廠營運管理之策略建議。

This study deals with important waste and energy management issues; specifically, it examines municipal solid waste (MSW) incineration—a viable technology for energy recovery and electricity generation. Due to its limited available land space and natural resources, Taiwan has 24 waste-to-energy (WTE) plants in operation, the highest density of MSW incinertaors (number of MSW incinerators/land area) in the world. The total design power generation capacity of these 24 WTE plants is 558.5 MW. If this capcity was fully realized, it could generate a revenue of over US$167 million/year. Taiwan’s MSW has high calorific value (1,873 kcal/kg) and low water content (53.4%), making it a valuable source of renewable energy. Approximately 6.5 million metric tons/year of MSW is currently being incinerated for energy recovery and waste reduction. This study applies the R1 formula to the WTE plants in Taiwan and finds that design power generation, capacity, and waste low heating value (LHV) are important design parameters for incineration facilities. This analysis of the energy production of these plants should be useful to others considering similar applications.
