Abstract
Abstract A pit barbecue apparatus embodies a fuel supporting tray or pan beneath which is positioned an electrical heating element. At an upper level of the pit enclosure, a food support grill is located, above which is a chimney. Heat from the heating element causes the wood fuel to smoke and smolder but not to blaze. The elevation of the fuel tray is self-regulating through bimetal support elements.
