陈腐垃圾-生活垃圾协同焚烧特性研究
Study of co-incineration characteristics of aged refuse and municipal solid waste
摘要
Abstract
To investigate the effect of co-incineration of aged refuse(AR)and municipal solid waste(MSW)on waste incineration characteristics,a 450 t/d mechanical grate incinerator was used as the research object to simulate the impact of the mixing ratio of AR and the moisture content of MSW on waste incineration characteristics,and field tests were conducted.The results show that the relative errors between the test results and the simulation results are within±5%.Increasing the mixing ratio by 1%advances the waste incineration process on the grate by 0.05 m.It reduces the rates of moisture evaporation,volatile release,and fixed carbon combustion by 0.21,1.63,and 0.59 kg/(m2∙h),respectively.With the mixing ratio of AR increasing,O2 content at the incinerator outlet increases,while CO2 and H2O contents decrease.Increasing the moisture content by 1%delays the waste incineration process on the grate by 0.19 m,and increases the moisture evaporation rate by 0.25 kg/(m2∙h),but decreases the volatile release and fixed carbon combustion rates by 9.82 and 0.88 kg/(m2∙h),respectively.The increase in moisture content leads to a decrease in CO2 and an increase in O2 and H2O at the incinerator outlet.The mixed waste heating value should be controlled in the range of 6 871～8 374 kJ/kg to ensure the flue gas temperature of the secondary air section above 850℃and the design heating value of the incinerator.关键词
