With　the　yearly　growth　of　urban　garbage　in　China,　the　reduction　and　harmless　treatment　of　garbage　has　become　more　and　more　urgent.　Compared　with　the　traditional　waste　treatment　methods　such　as　landfill　and　incineration,　pyrolysis　treatment　of　garbage　has　the　advantages　of　less　dioxin　emission　and　less　secondary　pollution,　and　has　received　more　and　more　attention　from　researchers　in　recent　years.　A　new　process　route　of　co-utilization　of　garbage　coupled　with　coal-fired　power　plants　is　proposed　for　the　needs　of　waste　treatment　at　the　county　and　township　level　in　China.　Combined　with　the　field　experimental　data,　aiming　at　the　actual　case　of　a　55　MW　coal-fired　unit　coupled　with　200　t/d　garbage,　the　process　is　verified　and　simulated　by　Aspen　plus　software.　The　experimental　and　simulation　results　show　that:　without　extracting　flue　gas　from　coal-fired　boilers,　the　tar　and　gas　produced　by　anaerobic　pyrolysis　of　garbage　can　be　burned　as　a　heat　source　for　drying　and　pyrolysis.　And　part　of　the　surplus　high　calorific　value　pyrolysis　oil　and　gas　can　be　sent　to　coal-fired　units　for　combustion.　When　part　of　the　middle　and　high　temperature　coal-fired　flue　gas　is　extracted　for　the　garbage　drying　and　pyrolysis　process,　the　anaerobic　pyrolysis　of　garbage　can　spare　more　high　calorific　value　oil　and　gas　for　combustion-supporting　and　peak　shaving.　At　the　same　time,　the　high-chlorine　garbage　charcoal　produced　by　garbage　pyrolysis　can　be　directly　sent　to　the　boiler　for　combustion.　The　on-site　detection　of　dioxins　produced　by　55MW　coal-fired　units　coupled　with　garbage　charcoal　is　carried　out.　When　the　garbage　charcoal　was　not　mixed,　the　total　dioxin　content　in　the　flue　gas　was　0.0061　ng　TEQ/m3;　when　the　garbage　charcoal　mixing　ratio　was　1%,　the　total　dioxin　content　in　the　flue　gas　was　0.0053　ng　TEQ/m3.　The　dioxin　content　did　not　change　significantly　before　and　after　mixing,　and　was　far　below　the　local　emission　standard.　The　high-humidity　flue　gas　in　the　drying　process　is　recirculated　into　the　oil　and　gas　combustion　hot　blast　stove,　which　is　beneficial　to　improve　the　surplus　pyrolysis　oil　and　gas　of　the　coupling　system.　Considering　the　safety　of　flue　gas　transportation,　the　actual　extracted　boiler　flue　gas　temperature　is　lower　than　the　combustion　temperature　of　pyrolysis　oil　and　gas,　so　the　actual　maximum　extracted　boiler　flue　gas　volume　in　this　case　(55　MW　unit　coupled　with　200　t/d　garbage)　is　no　more　than　2%　of　the　total　boiler　flue　gas　volume,　which　has　no　significant　impact　on　the　overall　performance　of　the　boiler.　©　2022　China　Coal　Society.　All　rights　reserved.
