Three questions; How hard is it to mix ratios of fuel such as coal and corn? If you were using a barrel do you just pour in certain amounts and let the auger mix it as it goes to the pot or do you have to premix it?
When you say it meet the 75% efficiency required by the government, what is your estimate of best efficiency attained while trying it? In other words how does it compare to pellet and corn stove efficiencies?
I would imagine there is more cleaning required using biofuels. How hard is the 520 to clean?
Looked at 1 of these http://www.portageandmainboilers.com/stoker.html
at a farm show this week. Looks like a well built boiler. The dealer said it would burn coal, corn, or wood pellets, but he did'nt know the difference between bit. and anth. coal .
Asked the price of the unit, show price $15,500 for the smallest unit, saw the look on my face
and tried to sell me 1 of the wood-coal boilers for $6500. no sale today
