【摘要】 为研究二次进风对柴煤炉的经济性和环保特性的影响,对CNCM-2.5Y型多功能加热炉进行了工业热态试验,测试了在室内风速下二次风率变化的排烟热损失,烟气中CO,CO2,NOX,SO2,O2的排放。结果表明在室内风速下二次进风对加热炉燃烧效率和烟气中有害气体排放有影响,二次风率为0.1～0.2时,加热炉的排烟热损失较小,CO,CO2,NOX,SO2排放浓度较低,得出室内风速下最佳二次风率为0.2,其排烟热损失为8.5%,CO为1055mg/m3,NOx为52PPm,SO2为96mg/m3,CO2为8.2%。更多还原

【Abstract】 In order to study the secondary air intake for economical and environmental effects on firewood stove,the industrial therma test was done and measured the heat loss of exhaust gas,the emisson of CO,CO2,NOX,SO2 and O2 with the different secondary air intake ratio indoor on the CNCM-2.5Y type multifunction heating stove.Results showed that the secondary air intake influened on combustion efficiency and harmful gases emissons.The heat loss of exhaust smoke was less and the emisson concentration is lower of CO,C O2,NOX and SO2.When the secondary air intake is 0.1～0.2,the optimal secondary air intake ratio is 0.1,and the heat loss of exhaust smoke was 8.5%,the CO emission concentration is 1055mg /m3,NOx for 52PPm,SO2 for 96mg /m3 and CO2 was 8.2%.更多还原
