Fluidized-Bed Gasification and Melting Furnace

Technology / Service Summary

Our fluidized-bed gasification and melting furnace employs a high-temperature combustion and melting process in which waste is gasified in the fluidized sand layer and the gas then reacts with air, eventually producing slag from melted ash. The facility is capable of performing this process without a fossil fuel supply, using only waste as an energy source.


Applied for public waste treatment plant


The facility recovers highly recyclable materials, such as steel and aluminum, from waste while producing slag from incineration ash. This means that the combustion process leaves nothing to be disposed of and effectively renders all waste incineration residues into reusable resources, realizing “zero emission” status.
Also, the lower volume of corrosive gas produced supports the use of a high-temperature high-pressure boiler that, in turn, allows for high-efficiency heat recovery for power generation.
