Hello, am Collins and am an Engineer by profession.
Based on the image my comment based on this is angled on the CPCB Standards for he incinerators. Incineration plants shall be operated (combustion chambers) with such temperature, retention time and turbulence, so as to achieve Total Organic Carbon (TOC) content in the slag and bottom ashes less than 3%, or their loss on ignition is less than 5% of the dry weight of the material.
I would like to talk more regarding this. Kindly get in touch
