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

Hydrogen Production: Biomass Gasification | Dhaiqirtment of Energy

Hydrogen Production: Biomass Gasification. Biomass gasification is a mature technology pathway that uhaiqi a controlled process involving heat, steam, and oxygen to convert biomass to hydrogen and other products, without combustion. Because growing biomass removes carbon dioxide from the haiqiphere, the net carbon emissions of this method can be

Choosing a biochar reactor to meet your needs - Biochar for

Terminology. A Reactor (or more specifically a chemical reactor) is a vessel designed to contain and control (chemical) reactions. A Pyrolyser is a reactor designed for thermal decomposition of biomass in a limited oxygen environment (= pyrolysis). A Gasifier is a reactor in which air is intentionally injected into the feedstock.

Principles of Pyrolysis - eagri.org

recirculated product gas. The high heat transfer rates from fluidized sand cause rapid heating of biomass particles and some ablation by attrition with the sand particles occurs. The bubbling fluidized bed gasifier is charachaiqized good temperature control and high reaction rates. They have greater tolerance to particle size range.

Design and Development of Updraft Gasifier Using Solid Biomass

Jun 04, 2017 · Updraft gasifier as tars are converted into smaller molecular Updraft gasifier is suitable for the solid biomass which has high-moisture (up to 60%), high-ash (up to 25%) and low-volatile fuels such as charcoal and it is also called as a countercurrent gasifier. Updraft gasifier has some advantages over downdraft gasifiers

Cogasification of sewage sludge in an updraft gasifier

Gasification of sewage sludge has been studied by several authors using different types of gasification reactors including fixed-bed downdraft gasifier [153,169,176], fixed-bed updraft gasifier

WO2013060474A1 - Method for operating a gasification reactor

The aim of a method for operating a gasification reactor (1) that comprihaiqi a reaction chamber (4) for the autothermic and/or allothermic gasification of haiqiceous combustible mahaiqial into useful gahaiqi is to improve the efficiency of a gasification reactor for gasifying haiqiceous combustible mahaiqial into useful gahaiqi with respect to useful gas yield and thermal yield as well as to the

AU2012100987A4 - Containerized Gassifier System - Google Patents

Abstract Containerized Gasifier System 5 The application relates to a containerized molten metal gasifier unit for the gasification of cellulosic biomass, coal and other types of haiqiceous feed to produce low BTU syngas for downstream application such as electric power generation, or chemical upgrading into one or more determined syngas-derived product.

Biomass Gasification Process - BioEnergy Consult

Aug 12, 2021 · Pyrolysis leaves a solid residue called char. In the second stage of the gasification process, this char is reacted with steam or burnt in a restricted quantity of air or oxygen to produce further combustible gas. Depending on the precise design of gasifier chosen, the product gas may have a heating value of 6 – 19 MJ/Nm 3.

Gasification charachaiqistics of steam exploded biomass in an

Gunarathne et al. [206] used biomass pellets to evaluate the effect of steam explosion pretreatment on the gasification performance using a pilot updraft gasifier ( Fig. 9) with air and steam

Mass and energy analysis of a 60 kW th updraft gasifier using

The total produced ashes and tar reference value, 0.86% of mass production and 9 g/m 3 respectively, were calculated on the basis of updraft and downdraft reactor averages from Liu et al. (2012

Ashaiqisment of the Potential of Biomass Gasification for

Jun 12, 2014 · This drawback restrains the application of the updraft gasifier, because these products released from pyrolysis would be detrimental in a heat engine; however, it could be used for heating applications . Another major drawback in updraft gasifier is due to high temperature at the grate melting ashes, leading to slagging. 3.4.2.

Coal Gasification: At the Crossroad. Technological Factors

Apr 21, 2021 · The designs of the OMB and Jinhua gasifiers have much in common with the GSP gasifier, the principles of which were developed in Germany as far back as the 1930s. The total number of large coal gasification plants in China with a unit capacity of above 700 t/day reaches 670 units, and their total installed capacity is larger than 350 million t

Updraft Gasifiers - an overview | ScienceDirect Topics

For an updraft gasifier, the height of the moving bed is generally greater than its diameter. Usually, the height-to-diameter ratio is more than 3:1 ( Chakraverty et al., 2003 ). If the diameter of a moving bed is too large, there may be a mahaiqial flow problem, so it should be limited to 3–4 m in diameter ( Overend, 2004 ).
