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)

Downdraft Gasifiers - an overview | ScienceDirect Topics

Fixed-bed gasifiers were developed first in the 19th century and have been sized from a few 10–100 kW thermal capacity. Updraft gasifiers have been developed for higher thermal capacities, but only for the provision of heat. Fixed-bed gasifier technology is relatively well-developed, but sometimes losses (i.e., heat, unburned material) are fairly high. Unfortunately, gas quality often does

Fluidized Bed Gasifier Design - ejmcm.com

In gasification, the efficiency of fluidized bed gasifiers is approximately five times thanthat of the fixed bed gasifiers. As a result of high mixing rates, in contrast to fixed bed gasifiers, there are no different reaction zones in a fluidised bed gasifier[10]. Also, fluidized beds have

Gasification and types of gasifiers

18/5/2021 · The fluidized bed gasifiers are categorized into two types as bubbling fluidized bed and circulating fluidized bed. Fixed bed gasifiers are typically simpler, less expensive, and produce a lower heat content producer gas. Fluidized bed gasifiers are more complicate, more expensive, but produce a syngas with a higher heating value. Biomass Air Producer Gas Fluidized Bed Air Riser Biomass

(PDF) A review of fixed bed gasification systems for biomass |

The fixed bed gasification systems are classified as updraft, Imbert downdraft, throatless downdraft, crossdraft and two stage gasifiers. Updraft gasifiers are suitable for gasification of biomass containing high ash (up to 15 %) and high moisture content (up to 50 %) and generate producer gas having high tar content (50–100 g/Nm3). The high temperature (830 oC) air gasification of biomass

5.2.1. Fixed (Moving) Bed Gasifiers | netl.doe.gov

Fixed- or moving-bed gasifiers commonly operate at moderate pressures (25-30 atmospheres). Feedstocks in the form of large coal particles 1 and fluxes are loaded into the top of the refractory-lined gasifier vessel and move slowly downward through the bed, while reacting with high oxygen content gas introduced at the bottom of the gasifier that is flowing countercurrently upward in the gasifier.
