Cooking apparatus configured as a grill-griddle having a body, a lid, a cooking grate, and a griddle are described. The grill-griddle may be arranged to have a combustion space within the body and an aperture in the cooking enclosure of the grill-griddle. The aperture may be on the side of the grill-griddle and allow one or more of the grill grate and the griddle to move in and out of the cooking enclosure. The grill-griddle configuration allows for the grill grate, the griddle, or both to move laterally through such transitions enabling enhanced control and flexibility in the cooking process.

The invention relates to auxiliary equipment for reburning combustion products. The technical result is that of accelerating the ignition of fuel and improving fuel combustion in a furnace. A device for reburning combustion products in a furnace is arranged above a combustion unit inside the body of the furnace and is in the form of a hollow body with a bottom inlet hole and a top outlet hole, on the side wall of which hollow body there is formed a horizontal row of evenly distributed air holes. Rectangular protrusions are formed to the right- and left-hand sides of each hole on the inside of the body of the device, said protrusions serving to feed supplementary air, which comes in via the holes, from the outer holes of the furnace into the body of the device, providing for accelerated incineration of residual combustion products without formation of a vortex in the air flows.
