Abstract
A vibratory feed mechanism for pellet fuel combustion device provides a spring-mounted feed plate communicating with a fuel reservoir and vibrated by an electric motor carrying an offset counterweight to move pelletized fuel from a first position on the feed plate to a feed orifice defined in the feed plate for communication of the pelletized fuel to a metering channel and a drop tube for conveyance to a fire pot. A control board communicating with an igniter, at least one thermocouple, a combustion fan, and the electric motor allow a user to set a desired parameter which controls the rate of pelletized fuel feed and temperature and operating conditions.
