Energy Generation and Resources Recovery from Refuse Incineration

Abstract

Refuse incineration plants with energy recovery have been successfully operated in a developing country. Waste heat recovered from the boilers can be used to generate electricity; 155 kwh of electricity could be generated for every tonne of refuse incinerated. The revenue collected from the electricity and scrap iron recovered from the incineration plant could offset the annual operating cost of the plant. After incineration, about 20% by weight of residues and ash are produced. Physical and chemical properties of the incinerator residue fractions passing 5‐mm sieve are analyzed. The incinerator residues after washing could be used as fine aggregate in concrete mixing.
