NOVELTY - The grill for a fuel in the form of a combustion element consisting of types of straws processed with microorganisms and types of hard woods and/or coconut husks processed with microorganisms, comprises upwardly opened combustion chambers (1) with a base surface and a lateral surface as side walls, a grid (2) arrangeable on the combustion chamber for the grill product, and an upwardly opened housing (3), in which the combustion chamber and the grid are arrangeable. The combustion chamber has openings (6) in its base surface for aeration and is mounted on a support (4).    USE - Grill for a fuel in the form of a combustion element consisting of types of straws processed with microorganisms and types of hard woods and/or coconut husks processed with microorganisms, useful in a grill system (claimed), and for the cooking of food on the open embers.    ADVANTAGE - The grill can be economically prepared, and is compact and easy to handle, transport and clean.    DETAILED DESCRIPTION - The grill for a fuel in the form of a combustion element consisting of types of straws processed with microorganisms and types of hard woods and/or coconut husks processed with microorganisms, comprises upwardly opened combustion chambers (1) with a base surface and a lateral surface as side walls, a grid (2) arrangeable on the combustion chamber for the grill product, and an upwardly opened housing (3), in which the combustion chamber and the grid are arrangeable. The combustion chamber has openings (6) in its base surface for aeration, is mounted on a support (4), which serves for spacing the combustion chamber from a rest surface, and is formed for receiving the respective combustion element. The interior of the combustion chamber has a diameter of the combustion element in horizontal direction and has maximum of 2/3 larger diameter than the diameter of the combustion element. The openings in the base surface maximally have 8 mm diameter and are uniformly distributed over the base surface. The total surface of the all openings corresponds to third of the total surface of the base surface. The support is designed, so that the distance between the base surface and the rest surface is 2 cm. Spacers are arranged to the base surface and/or the lateral surface in the interior of the combustion chamber for centering the combustion element. Additional six openings are arranged in the lateral surface for aeration. The combustion chambers are connected with one another over a path and are arrangeable in the common housing. The grid has a center area for each combustion chamber. The center area is centrally arrangeable over the combustion chamber. The grid has grooves radially outwardly running from the center area. The grooves have slits running on a transition area between the grid surface and the internal wall surface of the groove lying in longitudinal direction of the groove. The silts are formed, so that fume and aroma substances that are in vapor phase from the combustion chamber pass through the slits. The grooves are taperedly formed towards the center area. The opening at the end of each groove removably lying from the center area is arranged in the groove base for flowing-off liquids such as fats present at the grid. INDEPENDENT CLAIMS are included for:    (1) a combustion element for a grill; and    (2) a grill system.
