木質系生質能源共生發電技術效益研究
Performance Analysis of Cogeneration System by Woody biomass
摘要
近年石化燃料缺乏及環境破壞問題，加上能源需求遽增，使再生能源之開發逐漸受到重視。生質能源為最豐富之再生能源之一，生質能具有取之不盡、用之不竭之優勢，生質能轉換過程中，可降低空氣污燃染及溫室氣體排放量，且含硫量為石化燃料之百分之一，因此生質能為值得開發之能源技術。 生質能轉換技術中又以氣化較具發展性，氣化為一多方面熱化學製程，可製造CH4、CO與Ｈ２之混合氣體，並適合運用在區域型之發電廠，氣化發電後之熱，進而結合汽電共生系統，包含渦輪機、吸收式空調及溫水系統並能使系統效率提升，因此本論文採用木質系生質能結合氣電共生系統為主題，輸出冰水、溫水、電力，並進行性能評估，以達到最佳之木質系生質能源汽電共生設計。

People have been in lack of fossil fuel and faced the problem of environmental damage recently. Besides, the need of energy has been increasing drasitically. As a result, people pay more attetion to the development of renewable energy. One of the richest renewable energy is biomass. It is an inexhaustible supply, which is the main benefit. In the process of using biomass, air pollution and Greenhouse Gas are reduced. Moreover, the sulfur it contains is only one hundredth as much as that produced by fossil fuel. Therefore, biomass is worth developing. Among all the skills of biomass conversion, gasification is the one that is worthy to be developed. It is a kind of Thermo-chemical conversion, which can make gas mixed with CH4, CO, andＨ２. Besides, it can be used in small-scale power-stations. The waste heat generated from gasification can be used in Cogeneration System, such as gas turbine, absorption air condition and water warming system, enhancing the efficiency of the whole system. Thus, this thesis adopts woody biomass together with Cogeneration System as the main theme. The efficiency is evaluated by observing the producing of chill water, warm water and electricity. The aim is to make the best design of woody biomass and Cogeneration System
