75 kgs of pellets pr hour ready to run? Thats 165 lbs converted.
The average Joe chipping fuel would be lucky to produce 80 lbs of chips pr hour using a home and garden chipper and it would still need to be dried. With 50% or greater waste.
I have done all the calculations with this. Pellets are by FAR more efficient to produce. You must factor all into this equation all your waste all your energy inputs, drying energy everything. Not just taking it at face value.
Those that have large chippers or a PTO chippers would surely be able to produce much more. But that comes at a much higher expense.
165 lbs of pellets retail cost today is $22.68 here in the US.
My pellet fuel reactors are 20% for efficient than our chunk fuel reactors of the past. They produce 1 kW pr 2.2 lbs verses 3 lbs or greater of the old reactors. It cost you nothing to bulk feed pellets, verses you need a very powerful auger to bulk feed chip fuels. You need a minimum of a 2 hp motor, this over 2 kW energy input that is taking away from the system and they are constantly turning. This is part of equation, it energy lost in process.
Pelleting is a heat process that is built in, So indeed it looks slower than chipper blowing out chips. However pellets are shedding moisture while in process plus they are two times more energy dense.
All your waste from chips must be factored. Your energy input to produce that waste plus the waste itself and your time. This is huge thing Im not seeing people factor.
