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

Biomass gasification models for downdraft gasifier: A state

Oct 01, 2015 · The positioning of reaction distribution regions, i.e. drying, pyrolysis, combustion and reduction, in a fixed-bed reactor differ depending on the type of gasifier. Updraft gasifier. In an updraft gasifier, the biomass is fed from top of the gasifier, while air is supplied at the bottom of the gasifier.

units can operate at atmospheric or higher pressure. The gasification medium is generally either air (air‐blown), oxygen (oxygen‐blown), steam, or combinations of these. 1.2.1 Fixed Bed Gasifiers Updraft Design The fixed bed updraft gasifier is considered the simplest configuration.

Design and Development of Updraft Gasifier Using Solid Biomass

Jun 04, 2017 · Description of the updraft gasifier. The length of 1 m biomass was fixed in parallel position in the reactor and slowly combusted with air. Outer layer of the biomass is first cracked and then, followed by other portion, is converted into char. Tars travel from bottom to top direction.

Updraft Gasifiers - Ascent Bio Energy

Downdraft wood Gasifier requires wood chips, biomass briquettes or wood like agro-residues (such as stems, stalks). If fuel flexibility is required and need for fuel switching (say from biomass to coal or from one biomass to another) is anticipated, the updraft gasifier would be suitable. For gasification of coal, updraft gasifier is suitable.

The Promises and Pitfalls of Using Wood - US Forest Service

Gasification is partial combustion of a carbon-rich material to produce a synthesis gas (syngas), a mixture of carbon monoxide, hydrogen, carbon dioxide, methane, water vapor, and nitrogen. Wood gas is one type of syngas. A carbon-rich biomass and a controlled amount of oxygen are combined at high temperatures in a gasifier. Updraft gasifiers

Supercritical gasification of wastewater from updraft wood

Nov 01, 2007 · Abstract. Supercritical water gasification (SCWG) of the wood tar fraction soluble in water is discussed. The mixture is collected downstream of an updraft wood gasification plant and presents tar compounds typical of low-temperature pyrolysis, with the highest yields attained by acetic acid, levoglucosan and 1-hydroxy-2-propanone.

Forestry residues and wood waste for biofuel - ETIP Bioenergy

Updraft gasifier Downdraft or Co-Current gasifiers In the downdraft gasifier, fuel is also fed from the top and gravitates in the packed bed where it is gasified. Air, oxygen or a mixture of air and steam is fed either from the top or the middle of the reactor and the gasification zones are similar to the updraft reactor.

carbonaceous waste of various human and natural activities. Currently, the biomass sources contribute 14 % of global energy and 38 % of energy in developing countries. It is derived from the various sources, including the by product from timber industry, agricultural crops, raw material from the forest, major part of household waste and wood.

Experimental gasification of biomass in an updraft gasifier

Jan 01, 2014 · The two most popular types of fixed-bed reactors used are the updraft gasifier and the downdraft gasifier. The updraft gasifier is easy to operate and has quite high conversion efficiency, but this type produces high levels of tar, as high as 0.2kg/[m.sup.3] [5], because the pyrolysis gases containing high levels of tar are extracted directly

Construction of the stove - Build A Gasifier

Primary Air Entry Gasifier Stove Introduction Unlike the traditional woodstoves demanding larger logs, gasifier stove is ideally suitable to burn fuels having smaller sizes. These fuels include wood chips, agricultural waste, forest residue, pellets and briquettes.
