Abstract: Using the existed municipal solid waste（MSW） incineration plants to co-incinerate with industrial solid waste（ISW） could not only effectively utilize the capacity of MSW incineration plants， but also co-dispose with ISW. The co-incineration ratio of ISW in the existed MSW incineration plants， the low heat value （LHV） of the mixture， and the limitation and influencing factors were analyzed， which proved that it was feasible for the existed MSW incineration plant to co-incinerate with a certain ratio of ISW. Four waste pit management schemes were provided, when ISW was co-incinerated in MSW incineration plants， and were analyzed and demonstrated， and the optimal scheme was recommended to provide reference for design， construction and operation of the related co-incineration projects.

Key words: municipal solid waste incineration, industrial solid waste, co-incineration, waste pit management, waste crane configuration
