The photo on the left shows a blower motor system that blows wood chip fuel into the new biomass boiler at Gundersen Health System. Blower systems have some advantages over screw feed systems including a more efficient burn and maintenance advantages. The fuel system is metered and electronically controlled to supply the appropriate amount of fuel when the boiler needs it. The fan blower forces the woodchips into the boiler burner through two tubes seen in the photo on the right.
