| 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 |

9/1/2009 · There are three types of gasifiers depending on the direction of flow of Producer gas inside the gasifier, namely Downdraft, Updraft and Cross draft. Among these types, Updraft gasifiers are used only for thermal applications while Downdraft gasifiers are not only suitable for all thermal applications (including those requiring relatively clean and tar-free gas), but are particularly suited
A Review on Gasification Process & Gasifier B. T. Tagad1 R. S. Waghmare2 L. P. Bharule3 S. R. Khisti4 S. B. Patil5 1,2,3,4,5D.V.V.P.College of Engineering, Ahmednagar, India Abstract— Every day human being consume lot of energy more than half of this e
Cross-draft Gasifier: •Air or air/steam mixtures are introduced in the side of the gasifier •Normally an inlet nozzle is used •The velocity of the air as it enters the combustion zone •The combustion (oxidation) and reduction zones •Cross draft gasifier are normally simpler ADVANTAGES ANDDISADVANTAGES OF VARIOUSGASIFIERS
Downdraft wood Gasifier requires wood chips, biomass briquettes or wood like agro-residues (such as stems, stalks). If fuel flexibility is required and need for fuel switching (say from biomass to coal or from one biomass to another) is anticipated, the updraft gasifier would be suitable. For gasification of coal, updraft gasifier is suitable
2.5.2 Design guidelines for downdraught gasifiers. The downdraught gasifier makes it possible to use wood as fuel and produce a gas with sufficiently low tar content to operate an internal combustion engine. There are other means of handling the tar problem but these may create their own problems. Fox example, use of charcoal as fuel involves a
Cross draft gasification is one of the simplest types of gasification; the reactor for this gasification is much like the updraft gasifier in that the fuel will enter from the top and the thermochemical reaction will occur progressively as this fuel descends into the reactor. The crucial difference is that the air will be enhaiqing the gasifier from the side of the reactor, rather than from the
Biomass gasification power plant: capacity from 200kw to 3000kw, 1kg woody biomass generate 1kw electricity, 1kw woody biomass produce 2-3m3/h syngas, syngas heat value 1100-1500kcal/m3.
Gasification of shredded cotton stalk is successfully carried out by developing an open core throat less downdraft gasifier reactor.The maximum calorific value of producer gas was found as 4.55 MJ m-3.Maximum gasification efficiency of 71.05 % was found at the gas flow rate of 18 m 3 h-1 and specific gasification rate of 192.51 kgh-1 m-2.The values of benefit cost ratio of the system operated by considering shredded cotton stalk are more as compared to the values obtained by using the
haiqi have developed a very small gasifier meant to act on an efficient cook stove, called the inverted downdraft turbo-stove gasifier. The stove has a high efficiency - of the order of 30 % to 35 %. The gasifier chamber is removable and therefore, could be emptied to save the resultant charcoal, reloaded with biomass, relighted and re-inserted

1/3/2020 · Chopra and Jain studied usage of cotton stalk in gasifiers, especially in the modified haiqi downdraft gasifier. They modified the feed hopper and the grate to make it useful for gasification of non-woody biomass like cotton stalk, coir dust, wheat straw etc. Koroneos and Lykidou [14] predicted the gas composition in downdraft gasifier using equilibrium model for cotton stalk feedstock.
It is a compact down draft type bio- mass gasifier used to run a Diesel Engine. Capacity is 5kw to 50 Kw. Claims that many types of feedstock can be used: wood waste, stalks of cotton, pluhaiqi, coconut haiqis, coconut palm stalks, maize cobs, rice husk, branches & twinges, briquettes of various agricultural residues, Certain Industrial wastes of paper and mill waste.
