摘要
目前降低NO_(x)生成与排放技术中,再燃技术具有改造费用低、锅炉运行效率高、降低NO_(x)排放效率显著等特点。通过分析超细粉、生物质气、天然气和H 2作为再燃燃料的机理、影响因素、优缺点和实际应用情况,比较了不同再燃技术降低NO_(x)排放的技术参数和经济性,发现H 2再燃技术降低燃煤锅炉NO_(x)排放具有较大优越性。
Among the current NO_(x) generation and emission reduction technologies,the reburning technology has the characteristics of low transformation cost,high boiler operation efficiency,and remarkable NO_(x) reduction efficiency.By analyzing the mechanisms,influencing factors,advantages and disadvantages and actual application situation of ultrafine powder,biomass gas,natural gas and H 2 as refuelling fuel,the technical parameters and ecnomy of different recombustion technology are compared to reduce NO_(x) emissions.It is obtained that H 2 as recombustion technology to reduce boiler NO_(x) emission has superiority.
