  • 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 avoid second-pollution of heavy metals and dioxin. In this background, a direct gasification and melting incineration process with co-current shaft furnace is put forward. In the new process, the main equipment is a shaft furnace. In which, MSW and combustion-supporting air are co-current from top to bottom. 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 under the condition of countercurrent and more CO2 are discharged from cocurrent reaction tube. It can be concluded that the co-current shaft furnace is more suitable for direct gasification and melting incineration process.
