Both wood chips and wood pellets can be automatically feed into the burn chamber by Screw Conveyors, transport belts, and vibratory feeders. And both make char that is small enough to be automatically removed from the burn chamber. And both also has a shape and size that allows enough air to move trug the burn pile to feed the fire (unlike sawdust that will compact and stop to much air for it to burn).
But to make pellets you have to go trough two more steps (making chips into sawdust, and then pelletize it) to make them from whole wood compared to wood chips. And it takes more energy, and more machinery and time. So why are pellets used and not just wood chips? Is there any advantage i have missed? Or is it just to have a way to use sawdust waste from production of wood products for something useful? And in that case wasteful if whole wood pieces is used to make it?
