Finally, it is possible to produce DME, an eco-friendly energy source.
- the combustible waste treatment system of the present invention extracts combustible wastes from various industrial and household wastes continuously generated as well as existing landfill wastes that are buried in a landfill to make solid refuse fuel (SRF), and thermally decomposes the SRF to make it finally eco-friendly. It is possible to produce DME, which is drawing attention as energy.
- SRF solid refuse fuel
- the combustible waste treatment system of the present invention in the process of crushing, drying, and crushing combustible waste selected from landfill waste and new waste through SRF (Solid Refuse Fuel) fueling process, the amount of combustibles and the amount of heat increase and the water content The ash content is reduced and the weight can be reduced by 69.3% compared to before fueling.
