The Anthrakings are really a leap forward in engineering from Leisure Line. The vertical tube furnace design is efficient, as long as the tubes are kept free of fly ash, and I hope that idea trickles down to other products.
What we have found because of the tubes the way they are oriented allows very little fly ash to collect. It ends up with very very little lost in efficiency if any. Our 220 prototype has almost 30 ton of coal through it now . The only area that gets cleaned is the pipe and outlet. The coal exhaust does not pass through the tubes just around them with the diffuser installed it is very turbulent inside the furnace causing most ash to fall.
