Abstract
Increasing concern about environmental disruption is requiring MSW incinerators further to reduce harmful effects on the environment. In response to the requirement, we are developing "K-ECO stoker incinerator" for the coming age, which features "Low environmental impact" and "High recycling efficiency". Applying FGR (Flue Gas Recirculation) to a plant with a capacity of 50t/d and optimizing the combustion control, we attained a flue gas reduction of 20% by reducing air excess ratio. from 1.6 to 1.3. In addition, dioxins concentrations in flue gas, bottom ash and fly ash were reduced due to higher combustion temperature by minimizing the excess air supply to the incinerator.
