A fixed-bed experimental reactor was employed to reveal the combustion characteristics in simulated municipal solid waste (MSW) beds. Temperature distributions, ignition front velocity, bed weight were measured during combustion and gas analysis was also performed for O2, CO2, CO, CxHy, NO, HCN. The moisture content in MSW was varied. For higher moisture content, the drying of material was finished much later and the ignition front temperatures, ignition front velocity and overall burning rate were found to drop. The average concentration of CO and CO2 from the bed was inversely proportional to the moisture level, and the highest concentrations of CO and CxHy were observed at middle level of investigated fuel moisture content. Measurements showed that NO and HCN emitted from the bed and reached the peaks simultaneously with the volatile matters, and the conversion ratio of fuel nitrogen to NO and average concentration of NO decreased with increasing moisture content.
采用固定床实验反应器来揭示模拟城市固体废弃物（MSW）床层中的燃烧特性。在燃烧过程中测量了温度分布、着火前沿速度、床层重量，并且还对O2、CO2、CO、CxHy、NO、HCN进行了气体分析。改变了城市固体废弃物中的水分含量。对于较高的水分含量，物料干燥完成得更晚，并且发现着火前沿温度、着火前沿速度和整体燃烧速率下降。床层中CO和CO2的平均浓度与水分含量成反比，并且在研究的燃料水分含量的中间水平观察到CO和CxHy的最高浓度。测量结果表明，床层排放的NO和HCN与挥发性物质同时达到峰值，并且燃料氮向NO的转化率和NO的平均浓度随着水分含量的增加而降低。
