I just tried out a simple "auto-defoamer" for the first time: powered defoamer in a small cup suspended a couple of inches above the water line. When the foam hits the top of the cup the foam immediately settles down. I've always used Atmos during each firing, added to the flue pan near the float box. It wasn't cutting it this year, thus the powder trial. I asked the supplier where I should hang the cup. He told me to hang it 6" upstream from the draw valve. Hmmmm......seems in opposition to common thinking. He replied that everyone is doing it wrong. So I took his advice and it seemed to work well. I think I probably used much less defoamer than before.
