ABSTRACT:
A chip-firing unit in which a chip container has a discharge attached to the container bottom to supply chips from the container to the inlet of a motor-operated fan attached to the container. The fan is connected to a chip burner and supplies the burner with chips and air drawn in by the fan. The discharge on the container is a pipe with an external thread and is rotated by the same motor which drives the fan. The other end of the discharge pipe provides an intake for the air to be mixed with chips by the discharge. The pipe, furthermore, has an interior enclosing a rod which carries a control unit for chips and air supplies to the fan. This rod is adjusted automatically by a regulator of the hot-water boiler type. Chips are continuously fed to the inlet of the fan during rotation of the pipe. One throttle is provided for controlling the air through the inlet to the pipe, and a second throttle and a regulating rod controls the chip supplied to the burner. The two throttles cooperate through the regulating rod.
