USE OF FUEL

As per pollution norms the incinerator temperature should be > 850° The Fuel helps to raise the temperature quickly and will reduce the formation of dioxins. Incinerating without fuel temperature raises slowly and leads to the formations of dioxins which is against the norms of Green Tribunal Order.

INCINERATION

The incineration of MSW involves combustion of waste leading to volume reduction (90-95%) and recovery of heat to produce steam that in turn produces power through steam turbines (Bhide and Sunderesan 1983). Basically, it is a furnace for burning waste and converts MSW into ash, gaseous and particulate emissions and heat energy. The efficiency of the technology is linked to the waste characteristics and their properties such as moisture content and calorific values. It requires high temperature of the order of 800-1000℃ and sufficient air and mixing of gas stream. The minimum temperature for burning carbonaceous wastes to avoid release of smoke and prevent emissions of dioxin and furans is 850℃. Depending on the nature of wastes and the operating characteristics of combustion reactor, the gaseous products derived from the combustion of MSW may include carbon dioxide (CO2), water (H2O, flue gas), oxygen (O2), nitrogen oxides (NOx), sulphur dioxide (SO2) and small. Minimum Moisture content should be <45%. Calorific value should be as high as possible; >1500 kcal/kg. Incineration of chlorinated plastic should be avoided as far as possible. The emission standards are prescribed in SWM Rules, 2016.
