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

gasification - Build A Gasifier

Principles of Gasification. All internal combustion engines run on vapor, not liquid. The liquid fuels use by petrol engines are vaporized before they enter the combustion chamber. The purpose of a gasifier is to transform solid fuels into a gas and to keep the gas free of harmful constituents. There are many solid biomass fuels suitable for

Circulating Fluidized Bed Combustion - ScienceDirect

Pressurized fluidized bed combustion is based on known components working in a combined advanced clean-coal system: fluidized bed, gas turbine and steam turbine. Taking into consideration P200 combustor, the combustion of coal takes place in the bed vessel at about 850 °C under high pressure (12 bar). PFBC technology is a one-step process for converting coal directly into power, with a number of advantages over conventional CFBC technology such as:

Downdraft Gasifiers - an overview | ScienceDirect Topics

In the downdraft gasifier, as shown in Figure 9.2, the gasification agent (air or O 2) is fed into the middle of the bed (combustion zone) above the stationary grate and the producer gas flows out of the gasifier from the bottom of the gasifier beneath the stationary grate. In this type of gasifier, the fed solid fuel moves downwards together with the gases through a drying zone, a pyrolysis

THE DUAL FLUIDISED BED GASIFIER The dual fluidised bed gasifier is an allothermal gasifier, where gasification and combustion take place in spatially divided reactors. The principle is shown in Figure 1. The gasification reactor is fluidised with steam and a bubbling fluidised bed is formed. The residual ungasified char is transported into the

A STUDY OF THE DESIGN OF FLUIDIZED BED REACTORS FOR BIOMASS GAS

circulating fluidized bed system proposed for the continuous combustion-gasification of biomass. The design is based on the principle that the char produced in the gasifier is circulated with the bed material and combusted in a separate reactor to generate the heat required for the gasification process. While high solid circulation rates are required to

BIOMASS GASIFICATION - nariphaltan.org

III THEORY OF GASIFICATION The production of generator gas (producer gas) called gasification, is partial combustion of solid fuel (biomass) and takes place at temperatures of about 10000C. The reactor is called a gasifier. The combustion products from complete combustion of biomass generally contain nitrogen,

Fixed Bed Gasifiers - an overview | ScienceDirect Topics

In the downdraft gasifier, as shown in Figure 9.2, the gasification agent (air or O 2) is fed into the middle of the bed (combustion zone) above the stationary grate and the producer gas flows out of the gasifier from the bottom of the gasifier beneath the stationary grate. In this type of gasifier, the fed solid fuel moves downwards together with the gases through a drying zone, a pyrolysis zone, an oxidization (combustion) zone and a reduction zone.
