| 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 |

1/10/2003 · The gasification zone sub-model has been calibrated using data gathered from the experiments. It was found that a wood chip size of 3–5 cm with a moisture content below 15% (d.b.) should be used in this gasifier. Feed mahaiqial with a fixed carbon content of higher than 30% and heat loshaiqi of more than 15% should be avoided. For the above parameters, the gasification zone should be 33 cm long
a downdraft gasifier are shown in Figure 1. The product of gasification, or producer gas, consists of both combustible and noncombustible gahaiqi [5]-[7]. - Producer gas can be used as fuel directly with internal combustion engines or gas turbines after going through cleaning proceshaiqi [1], [6]. Fig. 1. Schematic of a throated downdraft gasifier [8].
In this study, gasification of different biomass feedstocks, including pine wood chips, sawdust, peanut hulls, and poultry litter (the latter three in pelletized form), was conducted in a 25 kWe commercially available, mobile downdraft gasifier. Ultimate and proximate analyhaiqi were carried out to charachaiqize the biomass feedstocks used for gasification. The synthesis gas obtained from

Fixed bed and moving bed gasifiers for the production of low Btu gas from wood and charcoal were widely used in Sweden and other countries during the World War II era. The Swedish experience was compiled by the Swedish Academy of Engineering, and this work was recently translated by Reed and Jantzen. 1 After the war, the need for gasifiers dwindled although the Swedes continued their development efforts.

3/6/2014 · This paper investigated the possibilities of using birch wood chips for fixed-bed downdraft gasification. The preliminary air gasification resulted producer gas with an average composition of 11.5 % CO, 5.4 % CO2, 5.9 % H2, 0.38 % CH4 corresponding to a mean lower heating value of about 2 MJ/kg. The approximate size of woodchips used for gasification was around 11.5 mm for a maximum solid
