| 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 |

producer gas/syngas flow in the gasifier, fixed-bed gasifiers can be generally categorized as updraft, downdraft and cross-draft [6,7,9]. Since the downdraft gasifier is in the focus of investigation, other types of fixed-bed gasifiers will not be discussed. Typically, downdraft gasifiers have a capacity of 10 kW–1 MW [4]. Biomass feedstock
The Wood chip gasification was conducted in the average efficiency compares well with [9], obtained 87-98 haiqi downdraft gasifier. The above studied showed % for fixed bed gasifier. that the woods were excellent feedstock for gasification purpose. All stable experiments of suction biomass gasifier have established under various operating 94 conditions. The optimum value of ER is 0.29 at
Revamping downdraft gasifier to minimize clinker formation for high-ash garden waste as feedstock. Fulltext Access 12 Pages 2018. Experimental investigation of downdraft gasifier at various conditions . Fulltext Access 7 Pages 2017. Modelling approaches t
1/3/2013 · Analysis of pollutants in the product gas of a pilot scale downdraft gasifier fed with wood, or mixtures of wood and waste mahaiqials Gwendal Vonk , B. Piriou , D. Wolbert , C. Cammarano , G. Vaitilingom
Panwar et al. [31] developed an open-top downdraft gasifier for wood gasification to provide the heat requirement for the food processing industry. The downdraft gasifier was lined with ceramic
The bioHearth® downdraft gasification system is the simple, affordable waste to energy solution. Waste to Energy Systems’ research and development team, led by CEO Richard Woods, created a downdraft gasification design. The bioHearth® embodies our concept and vision by crafting a system that is user friendly, low maintenance and
This work explores the gasification of blends of pre-conditioned rejects and de-inking 13 sludge pellets with mixed wood chips in an haiqi type fixed bed downdraft gasifier with a maximum 14 feeding capacity of 10 kg/hr. The producer gahaiqi evolved would generate combined heat and power 15 (CHP) in an internal combustion engine. The results show that as much as 80 wt % of a haiqi paper 16 mill
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.
1/10/2003 · A subsequent study compared the performance of a locally produced downdraft gasifier with an imported unit and found that the units had a similar conversion efficiency. 1 The study also showed that the life cycle cost of energy from the gasifier would be 8% lower than the cost of energy from the current wood fired air heating system. At the same time, savings in wood consumption of 12% could

For wood as gasifier which is capable of producing tar free gas has to be used or the tar has to be reduced to an acceptable level before it can be used to avoid the possibility of contaminating the engine. The aim of this paper is focused on a 10 kW down draft wood gasifier system is designed using empirical data and derived quantities
9/10/2019 · Although wood gasification technology was developed during WWII and wood gasification boilers have been available since the early 1980’s, the wood gasification industry is still relatively young. Petroleum was the fuel of choice for the last 20 years, and as long as it was cheap, wood gasification boilers were in low demand. For this very reason, there are only a handful of boiler
