用於鍋爐之氮氧化物控制技術原理及優劣評析

The Analysis of Principles, Advantages and Disadvantages of de NOx Technologies Using on Boilers

摘要


氮氧化物主要來自於車輛廢氣、火力發電站和其他工業燃燒器或鍋爐所產生的廢氣,它會刺激肺部,造成呼吸系統疾病,排放於大氣中也會造成酸雨等環保問題。氮氧化物的型式,主要包含熱式氮氧化物、燃料式氮氧化物以及瞬式氮氧化物,而目前氮氧化物控制技術,主要分為三大類,分別為燃料前處理技術、燃燒過程改善技術及廢氣後處理技術。本文將介紹這三大類氮氧化物控制技術的原理及其減量效果,同時評析這些技術之優缺點。

The emission of NOx was major from exhaust emission of vehicles, power stations, industrial burners or boilers. It will cause the healthy and environmental problems such as acid rain and respiratory disease. Based on production mechanism, NOx could be divided three types: thermal NOx, prompt NOx and fuel NOx. The de-NOx technologies have three types: fuel specification, combustion modification and post-Combustion treatment. This article introduced the theories, effects, advantages and disadvantages of these technologies.
