Application Prospects

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/Nm3to 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.
