Study on Iow-NOx combustion technology for coal-fired industrial boilers

摘要：

　　Based on the analysis of combustion conditions of the experimental grate-fired furnaces with a capacity of 2t/h,a low-NOx combustion transformation program was proposed.The effects of influencing factors including fuel staged combustion,air staged combustion and circulating flue gas on NOx emissions were investigated.The results show that when air-staged combustion based on separate room air distribution and fuel staged combustion,NOx emissions decreased from 260-359 mg/Nm3 to 137-182 mg/Nm3.And when circulating flue gas rate reached 10-15%,NOx emissions decreased 3-5%.These results indicate that the NOx concentration in the flue gas of the grate-fired furnaces with low-NOx combustion technology was below 200 mg/Nm3.which has great application prospects.
