氣化複循環發電系統性能分析

整合氣化複循環發電(Integrated Gasification Combined Cycle, IGCC）是當今國際公認最潔淨的煤炭發電方式。煤炭經過氣化製程，產生的合成氣經燃氣淨化系統，將硫氧化物等污染物去除，成為潔淨的燃料，而以複循環方式發電，不僅可提高電廠的熱效率，亦可以減少污染性氣體與二氧化碳的排放。所以氣化複循環發電技術是一兼具高發電效率、低污染排放且燃料使用較彈性，此技術將成為未來火力發電的技術主流。本論文經由理論探討IGCC系統之熱功性能，及利用GT PRO軟體模擬運行，以驗證IGCC發電之效能，並從國際已建IGCC示範電廠運轉的經驗，探討台灣未來建造IGCC電廠最適的組合。研究結果顯示IGCC的淨效率雖與目前先進的超臨界機組相當，但未來可以提升效率的空間則更大，將來可以結合二氧化碳捕獲封存比之超臨界機組更具優勢。宜應密切觀察國際發展情況適時引進，使台灣火力發電和國際齊步晉入新的紀元。

Integrated gasification combined-cycle power generation (IGCC) is today internationally recognized as the cleanest way for coal power generation. After the coal gasification process, the resulting syngas through the gas cleanup system will remove the sulfur oxides and other, become the clean fuel, in order to power generation by combined-cycle method, not only can improve the thermal efficiency of power plants, but also can reduce pollution and carbon dioxide gas emissions. Therefore, gasification combined-cycle power generation technology has both high power generation efficiency, low pollution emissions and more flexible for fuel use, this technology will become the future mainstream of thermal power generation technology. In this paper, through the Theory of thermal power IGCC system performance, and the use GT PRO software to run simulations to validate the performance of IGCC power generation, and from the international demonstration power plant to run their experiences and explore the optimal combination of Taiwan to build IGCC power plants in the future. The results showed that the net efficiency of IGCC although with the ultra-supercritical units are equivalent, but it can enhance the space of efficiency even greater in the future, and can combine the CO2 capture and storage more than the supercritical units. It is desirable to closely observe of the international developments and introduction in a time, and make Taiwan entering a new era in step with international thermal power generation.
