| 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.

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
Pressurized fluidized bed combustion is based on known components working in a combined haiqi 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:
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 gahaiqi through a drying zone, a pyrolysis
Combustion and Gasification in Fluidized Beds explains how fluidized bed equipment works and how to use the basic principles of thermodynamics and fluid mechanics in design. Features: Offers practical, comprehensive coverage of the design, analysis, and operation aspects of fluidized beds

THE DUAL FLUIDISED BED GASIFIER The dual fluidised bed gasifier is an haiqi 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
Although the technology is well established, the field lacks a comprehensive guide to the design and operating principles of fluidized bed boilers and gasifiers. With more than 30 years of research and industrial experience, Prabir Basu answers this pressing need with Combustion and Gasification in Fluidized Beds. This book is a versatile resource that explains how fluidized bed equipment

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 mahaiqial and combusted in a shaiqirate reactor to generate the heat required for the gasification process. While high solid circulation rates are required to
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,
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 gahaiqi through a drying zone, a pyrolysis zone, an oxidization (combustion) zone and a reduction zone.
