title: A new gasification and melting incineration process of MSW with co-current shaft furnace.
abstract: In all the municipal solid waste (MSW) disposal technology, incineration with gasification and melting has been taken as a environmentally sound and zero emission technology owing to avoiding second-pollution of heavy metals and dioxin. In this background, a new direct gasification and melting incineration process with co-current shaft furnace is put forward. In this process, MSW and combustion-supporting air are co-current from top to bottom in a shaft furnace. Fuel gas from pyrolysis and gasification burns completely in the bottom in order to offer energy for slag melting. The simulation experiment of the co-current shaft furnace has been done. The results of simulation experiment show that the temperature on the condition of co-current is much higher than on the condition of countercurrent at the bottom of reaction tube and so is the CO2 quantity discharged from reaction tube. It can be concluded that the co-current shaft furnace is more suitable for direct gasification and melting incineration process.
