中文摘要 摘要
  本文之主要目的為探討自由活塞史特靈引擎與工研院小型焚化爐實際搭配之可行性分析,期望能經由自由活塞史特靈引擎來回收焚化爐廢熱並推動引擎活塞來發電,達到節約與環保之双重功效以符合先進國家追求永續能源的能源策略。
  為了建立此引擎與焚化爐結合之系統,本文建立一熱傳模式,在模式中吾人利用有限溫差與有限面積熱傳與引擎內部之熱短路來模擬實際引擎在運轉中之外不可逆性與內不可逆性,並利用朗氏最佳化方法來求解在固定熱源與固定熱沉溫度下引擎所能達到的最佳性能。
  爲了要確定二次燃燒室中能量足夠與否,本文對焚化爐日處理量16噸之廢棄物進行質能平衡,估算出在一般情況下,在不影響焚化流程時約有316KW之廢熱可供給引擎運轉所需之熱能。
  值得一提的是史特靈引擎屬外燃引擎,也就是說所有作動之能源完全由外部經熱交換器傳入引擎內之流體,所以高低溫熱交換器面積間之大小非常重要。在一固定總熱交換器面積下,本文也針對高溫處與低溫處之熱交換器面積做了最佳化。


英文摘要 Abstract
  In this thesis, the feasibility of recovering the wasted-heat from a small-scale incinerator (designed by Industrial Technology Research Institute) and generated the electric power by a linear free-piston Stirling engine is investigated. The success of this study is beneficial to our environmental protection and energy conservation policies, which are equally important for a developed country to pursue the strategy of energy sustainbility.
  A heat-transfer model is used to simulate the integration system of the Stirling engine and the incinerator. In this model, the external irreversibility is modeled by the finite temperature difference and by the actual heat transfer area, and the internal irreversibility is considered by a internal heat shortage. Under a fixed temperature source and a fixed temperature sink, the optimal engine performance can be obtained by the method of Lagrange multipliers.
  The analysis of mass and energy balances was also performed for the burning of a typical waste at the rate of 16 ton per day, and found out the waste at the rate of 16 tone per day, and found out the waste energy up to 312KW is otherwise expelled to the atmosphere can be recovered by the Stirling engine without the interruption of the stand-alone operation of incinerator.
  It should be mentioned that the Stirling engine is an external combustion engine, which mean the energy used to power the engine is entirely obtained from the external source. Therefore the available area that is used to receive the heat from the heat source or that to expel the heat to the heat sink is very crucial to the engine’s performance. Under a fixed total heat transfer area, the optimal area ratio (cold side area to hot side area) is also calculated in this study.
