Patent ID: 8607717

Claim:
A process for thermal oxidation of waste comprising the steps of: a burn down step in a first chamber, where waste is burned down by providing a first stream of air flow from a bottom inlet on the first chamber and through the waste and a second stream of air flow is provided from a top inlet on the first chamber, and a combustion step in a second chamber, gas from the first chamber is exposed to high temperature and an air flow is provided to the second chamber, wherein the combustion step in the second chamber is carried out for a predetermined time period, and wherein a flow rate of gas/air exiting the second chamber determines an air flow rate from the bottom inlet in the first chamber, such that the air flow rate from the bottom inlet in the first chamber increases when the flow rate of gas/air exiting the second chamber decreases, and the air flow rate from the bottom inlet in the first chamber decreases when the flow rate of gas/air exiting the second chamber increases.
