Hi there. I am looking into starting a malting plant and would like to dry the wet malt with a biomass burner. It would require around 800,000btu per hour for 20 hours. I would also like to be able to use the system to dry grain in the fall and possible use it to heat a shop and a couple houses if the price of natural increases in the future. Thank you for taking the time to post your boiler on here. I was wondering about using a vac truck tank (the rear door opens wide (6.2 feet) on hydraulics and I would be interested in leaving the tank on the frame so I could still use the hoist to empty out the ashes (build a hitch on the front to move). Would a water jacket be an absolute must and the tank will warp out of shape without one? Was planning to cover the ceiling of the tank in pipes that I could circulate the glycol through. Stupid idea or could it actually work?
