ABSTRACT:
A fuel feed system for feeding particulate combustible material to a stove, a heater, furnace or the like, referred to herein as heating equipment, and the same in combination with such feed system wherein the combustible material is wood, preferably wood chips. A container is provided for holding a supply of the wood chips to be burned and a cover removably mounted on the container which, during use, is sealed on the container so as to provide a sealingly closed container. The conveyor system for moving the wood chips from the container to a burner in the heating equipment includes a first conveyor and a second conveyor for moving the wood chips along respective different flow paths and a drop box between such first and second conveyors that provides a contiguous flow path along the conveyor system. A normally closed one way flow valve is located in the drop box to prevent reverse flow through the drop box from said second to said first conveyor. The cover is slidably mounted on said container and arranged such that the entire cover is raised vertically off the container when one edge thereof is lifted and thereafter the cover can be slid laterally on a slide mechanism.
