Incineration
Types
-
More controlled form of private waste incineration, containing the burning material inside a metal barrel, with a metal grating over the exhaust
This was the fixed and much older version for grate. Lined with the brick while lower or ash pit is made up of metal
Controlled combustion, burn back prevention systems are essential as dust when suspended resembles the fire catch phenomenon
This grate is capable for hauling waste from combustion chamber to give way for complete and effective combustion
-
The air gets going through the bed when a point come where sand granules separates and let air pass through them and here comes the part of mixing
-
The rotary-kiln incinerator is used by municipalities and by large industrial plant. Movement of the cylinder on its axis facilitates movement of waste.
In the primary chamber, there is conversion of solid fraction to gases, through volatilization, destructive distillation and partial combustion reactions.

Current Technologies
- Incineration of waste materials converts the waste into ash, flue gas, particles and heat
- These products are later used for generation of electricity
- The gases, flue gases are first treated for eradication of pollutants before going in to atmosphere
- Incineration reduces the mass of the waste from 95 to 96 percent
- Modern incinerators are equipped with pollution improvement systems, which play their part in cleaning up the Flue gas and such toxicants
Advantages
- Volume and weight reduced (approx. 90% vol. and 75% wt reduction)
- Waste reduction is immediate, no long term residency required
- Small disposal area required
Definition
Waste treatment process that involves the combustion of organic substances contained in waste materials
