Product Description

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

Are downdraft rangehoods good? Explained by FAQ Blog

2022/5/30 · Which is better downdraft or updraft? This type of ventilation is the most effective for removing smoke, odours, and particulates naturally rise into the vent. Visually, updraft ventilation can be more obtrusive, but your kitchen will stay cleaner, you'll successfully vent more heat, and capture more odours then you will with a comparable downdraft unit.

Downdraft Gasifier | Scientific.Net

Abstract: Gasification is a green technology, which produces combustible gas mixture from solid biomass by partial oxidation at elevated temperatures. Synthesis gas, the desired product of such technology, has more uhaiqi than the solid biomass. In this study, a locally developed pilot scale fixed-bed downdraft biomass gasifier was examined.
