Combustion modelling of an industrial municipal waste combustor in Malaysia

Disposal of Municipal Solid Waste (MSW) in Malaysia by open incineration is increasingly becoming a problem. There is public concern about any pollutant emissions. Design requirements of high-performance incinerators are sometimes summarized as the achievement of 3Ts (time, temperature, and turbulen...
