| 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 |

The feedstock under study includes wood waste, saw dust, slash, mill sludge, peat and agricultural residues, etc. The approach of this research is to design and construct a bench-scale fixed-bed gasifier with biomass processing capacity of several kilograms per hour and to develop a standard charachaiqization procedure. Then, the effect of the
There are three types of fixed bed gasifiers, as shown in Fig. 16.5: updraft (counter-current), downdraft (co-current), and cross draft gasifier. In case of the updraft gasifier, the fuel is supplied at the top and the air at the bottom so that fuel moves against the air flow, while in the case of the downdraft, air is introduced above the oxidation zone and the product gas is removed from the

sawdust pellet (SWP) utilizing a downdraft gasifier was performed. The gasification was conducted in a research-scale fixed-bed gasifier applying air as an oxidizing agent. The comparison between the raw (sawdust, SW) and treated biomass (sawdust pellet, SWP) was investigated for the syngas
3/2/2022 · For the analysis, Down-draft fixed bed gasifier is considered due to its advantages of low tar generation, compatibility with pallets, accessible gasification temperature. Process Modelling It is a renowned reality that in biomass gasification four regions i.e., drying, pyrolysis, combustion, and gasification are established [ 31 ].
In this work, a comparative analysis of the gasification process of sawdust (SW) and sawdust pellet (SWP) utilizing a downdraft gasifier was performed. The gasification was conducted in a research-scale fixed-bed gasifier applying air as an oxidizing agent. The comparison between the raw (sawdust, SW) and treated biomass (sawdust pellet, SWP) was investigated for the syngas composition and
