MUNICIPAL WASTE INCINERATION is the most advanced level of the waste disposal/treatment hierarchy:
indiscriminate dumping, controlled dumping, landfilling, sanitary landfilling, and mechanical treatment. Solid waste arises from human activities- Domestic commercial, Industrial, agricultural, wastewater treatment and soon.
Type of Waste:
1. Domestic Waste : Waste from household activities, including food preparation, cleaning, fuel burning, old clothes and furniture, obsolete utensils and equipment, packaging,newsprint, garden wastes etc.
2. Street Sweepings: The waste is dominated by dust, soil, and varying amounts of paper metal and other litter from the streets. In lower-income cities, street seeping may also include drain cleaning and domestic waste dumped along the roads plant remains and animal manure.
3. Construction and Demolition Waste : The composition of the waste depends on the type of wood packaging materials and the like.
The incineration system provides an effective means of reducing the volume of Municipal solid. Municipal solid waste incinerator converts waste into ash Combustible gases at 1000°C in the primary chamber Secondary Chamber temperature is raised up to 1450°C for atleast 2 seconds to incinerate the wastes with a content of more than 1% of halogenated organic substances. The incinerator reduces most combustible solid waste to nearly 1-2 percent by volume and 3 percent by weight.
