Influence of Oxygen Mass Flow Rate Variation on the Performance of a Dual-Chamber RDF-Fueled Incinerator.

Abstract

Oxyfuel combustion is the process of burning fuel using pure oxygen with a high concentration of up to 95%. Combustion with
pure oxygen aims to produce exhaust gases consisting almost entirely of CO₂ and H₂O (complete combustion), enabling the
separation or capture of CO₂ from the exhaust gases. This study aims to analyze the performance of the waste incineration
process using a fixed grate dual chamber incinerator fueled by RDF with varying oxygen mass flow rates. The method used in
this research is an experimental approach, where oxygen is added to the second chamber of the dual-chamber incinerator by
varying the oxygen mass flow rate to achieve optimal performance from the incinerator. The tests were conducted with four
variations, starting from the smallest variation of 178.30×10⁻⁴ kg/s, 196.13×10⁻⁴ kg/s, 213.96×10⁻⁴ kg/s, and 231.79×10⁻⁴ kg/s.
The results show that the solid fuel consumption rate for the first to the fourth variation were 49.720 kg/h, 49.010 kg/h, 49.300
kg/h, and 49.910 kg/h, respectively. The combustion efficiency for the first to the fourth variation were 92.61%, 90.38%,
88.99%, and 87.92%, respectively. Therefore, the first variation had the highest efficiency value..
