Hello Varin
Using Sa Kaew as a case study, I have found in a literature attached in the previous mail that dioxin can be destroyed as follows:
• Raising the primary air outlets and balance out by secondary air from the wall; increase primary air which are installed under a vibrating grate and reduce secondary air resided at the wall
• In the combustion, the temperature should be over 850 C and gas residence time of 2 s
• Before the stack, when the temperature is over 250 C, employ semi-drying lime scrubbing and bag filtration coupled with activated carbon injection adsorption. Thie technique is similar to Gidec in Had Yai.
Best wishes, Pooh
