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

Biomass gasification models for downdraft gasifier: A

1/10/2015 · The downdraft gasifier has four distinct zones: (1) drying zone, (2) pyrolysis zone, (3) oxidation zone, and (4) reduction zone. The product gases leave at a point just below the grate of the gasifier, which enables partial cracking of the formed tars and hence a gas with low tar content is produced.


58 industry waste stream tonnages that are of interest here, which are often too low for other gasification 59 technologies such as fluidised beds. 60 Although there has been extensive research carried out on the application of fixed bed downdraft 61 gasification to process biomass and wastes in general [5, 6], very little work has been done

9/11/2009 · Modeling of biomass. gasification implies the representation of chemical and physical phenomena. constituting all the four zones of the gasifier (pyrolysis, combustion, reduction, and drying) in the mathematical form. The models of downdraft. biomass gasification can be categorized into two groups: (1) Equilibrium models.

BioHearth - Downdraft Gasification System by Waste to Energy

GASIFICATION PROCESS Municipal Solid Waste (MSW) requires the initial step of recycling, then it is treated much the same as industry, agricultural, and forestry waste. Refined and processed into briquettes, the fuel stock is then fed to the gasifier system and converted into a high grade “syngas.” The syngas goes through a filtering unit before it is ready to fuel the engine to produce

Gasification – European Biomass Industry Association

Gasification is the conversion by partial oxidation (i.e. more oxidizing agent than for pyrolysis but less than for complete combustion) at elevated temperature of a carbonaceous feedstock such as biomass or coal into a gaseous energy carrier. Gasification takes place in two main stages. First, the biomass is partially burned to form producer gas and charcoal. In the second stage, the carbon


A 100 lb/hr laboratory scale solid waste gasifier was constructed in 1978 (see Figure II). The unit is batch fed through -a hatch on the top of the fuel hopper. The gasifier consists of the reactor shown in Figure II, a ten channel scanning thermocouple system, and a small air blower.
