天然气再燃降低锅炉NO_X的排放

Reduction of boiler NO_X emission through natural gas reburn

介绍了常规天然气再燃技术的原理、特点及缺点 ,列举了国外主要天然气再燃的应用项目。介绍了我国 NOX污染现状 ,过去我国环保要求较低加上经济上的考虑 ,对 NOX脱除未予应有关注 ,当前控制 NOX的应用方法皆不尽理想。天然气再燃技术降 NOX效果好 ,技术成熟 ,投资较少 ,无二次污染 ,我国的天然气储备丰富 ,随着环保要求的提高 ,该技术将得到广泛的应用。最后介绍了高级天然气再燃 (AGR)、淡燃料天然气再燃和胺增强天然气再燃 (AEFLGR)

The principle, feature and shortcoming of traditional natural gas reburn technology were introduced. The major application projects of natural gas reburn in the world were listed. The current NO X contamination status of our country was briefly introduced. In the past, since our country's environmental requirement was relatively low and there was much consideration of economic cost, the desulfuration of NO X was not paid proper attention. The currently using methods of controlling NO X are not so ideal. However, the mature natural gas reburn technology gives a perfect effect of NO X reduction with less investment and little secondary pollution. This technology will be widely used in the future with abundant natural gas reserve in our country and with the improvement of environmental requirement. In the last, advanced gas reburn, fuel lean gas reburn, amine-enhanced fuel lean gas reburn were introduced.
