摘要

本研究將氫氣輔助燃燒應用在2噸貫流式重油蒸氣鍋爐，我們將甲醇重組反應器與鍋爐進行整合，甲醇重組反應器產出的氫氣混合氣（H_2+CO_2）則是利用氫氣槍直接噴入鍋爐燃燒室中，來進行氫氣輔助燃燒。在性能測試方面，我們比較實施氫氣輔助燃燒前後煙氣之NOx、CO的排放濃度變化，並進行系統長期運轉測試，分析鍋爐的節能以及減碳效益。目前鍋爐採用氫氣輔助燃燒後共累計運轉291天，在這運轉期間，系統沒有任何異常狀況發生，同時鍋爐的油水比提高6.03%。

This study applied hydrogen assisting combustion system to the 2 t/hr once through steam boiler using heavy oil as fuel. The hydrogen generator that is methanol reformer is integrated with the boiler. The methanol reformer can generate hydrogen mixture gas (H_2+CO_2). The hydrogen mixture gas was injected into combustion chamber of the boiler using hydrogen lance to proceed hydrogen assisting combustion. For performance testing, we compared the concentration variations of NOx and CO in the flue gas before and after using hydrogen assisting combustion. Meanwhile, the long term running test was performed to analyze the benefits of energy saving and CO_2 reduction. So far the boiler have run 291 days after using hydrogen assisting combustion system and no abnormal problem occurred. Compared with baseline test results, the average water-oil ratio of boiler increased 6.03% during this period of running.
