You are the one who is most familiar with concentrator rings and you suggested one for my large TLUD. Frankly, I've never been too terribly impressed with concentrator rings until I saw one in action at the TLUD Summit. I am planning on adapting one to my large
TLUD. Are there guidelines or specifications for them? Should they be an area percentage of the stack or should they be in the area percentage of the feedstock barrel?<br>
