Product Description
Comparison of Grate Furnace Incineration Treatment Technology and Pyrolysis Gasification Treatment Technology
Compare Content Grate Furnace Pyrolysis Gasifier
Incineration Mechanism The Garbage Is Directly Burned, The Combustion Temperature Is 800~1000°C, The Incineration Mechanism Is General Using Two-Stage Treatment, The Garbage Is Now Pyrolyzed And Gasified, And Then Small-Molecule Combustible Gas Is Burned. The Combustion Temperature Is 850~1100℃. The Incineration Mechanism Is Advanced.
Furnace Structure And Grate Material The Structure Is Complex And The Shape Is Large; The Grate Works Under High Temperature, And The Requirements For The Grate Material Are High The Structure Is Relatively Simple And Compact; The Grate Works In A Low Temperature State, And The Requirements For The Grate Material Are Low
Types Of Garbage Dispose Of Domestic Waste It Can Process Domestic Waste, Industrial Waste, And Hazardous Waste With High Calorific Value (Including Medical Waste)
Area (300t/D) 40-50 Acres Higher 30-40 Acres Lower
Operating Cost Fly Ash Emissions Fly Ash Discharges A Lot, Accounting For About 5% Of The Total Garbage Fly Ash Emission Is Low, Accounting For About 1% Of The Total Garbage, Which Is Environmentally Friendly
Acidic Substance And Dust Emission The Original Value Of Acidic Substances Such As So2 And Nox Is Relatively High; The Dust Emission Concentration Is 6000~8000mg/Nm3 The Original Value Of Acidic Substances Such As So2 And Nox Is Relatively Low: The Dust Emission Concentration Is ≤3000mg/Nm3
Plant Environment It Is Difficult To Control The Environment In The Plant Area. The Incinerator Workshop Has A Certain Amount Of Bottom Ash And Leachate, Noise, And Odor Pollution. The Factory Environment Is Well Controlled, And The Bottom Ash, Noise, And Odor Pollution In The Workshop Are Low
