ABSTRACT:
Chip gates are provided adjacent the lower end of an inlet chute to a presteaming vessel for a digester in a pulp production system. The chip gates are operated to maintain a level of chips within the inlet chute sufficient such that the chips preclude egress of noxious odorous gas from the presteaming vessel, while simulataneously the chips are discharged into the vessel.
