Introduction

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Incineration and other high-temperature waste treatment systems are described as “thermal treatment”. Incineration of waste materials converts the waste into ash, flue gas and heat. The ash is mostly formed by the inorganic constituents of the waste and may take the form of solid lumps or particulates carried by the flue gas. The flue gases must be cleaned of gaseous and particulate pollutants before they are dispersed into the atmosphere. In some cases, the heat generated by incineration can be used to generate electric power.

 

Incineration Technologies

There are some different methods of waste burning process that make them specialized based on waste type, dimension, calorific value, volume, humidity, and so on. Whatever is technology, while incineration and gasification technologies are similar in principle, the energy produced from incineration is high-temperature heat whereas combustible gas is often the main product from gasification. Hereunder table shows the main incineration technologies technically categorized by waste type application:

 

Solid Waste

Liquid Waste

Gas Waste

Catalyst

Sludge

Rotary Kiln

 

 

Fluidized Bed

 

 

Liquid Injection

Multiple Heart

Catalytic Combustion

Waste-gas Flare

Moving Grate

As it may be deemed, each technology applies for incineration of individualized waste types based on some special characteristics mentioned above. Extracting from table, the most suitable technologies for municipal solid waste (MSW) are:

Rotary Kiln, Fluidized Bed, & Moving Grate.
