Abstract: An apparatus, method, and system for combusting bridging fuel which includes biomass material. The apparatus includes an enclosure having a relatively thin wall defining a firebox. A temperature sensor is positioned on the exterior of the wall of the firebox. A controller is operatively connected to the temperature sensor and the fuel feed conveyor.
