The pot has a side wall (3) surrounding a base (2), and a set of openings (4) regularly distributed in the fire pot for air passage. The ratio of a total area of the openings (4) to a total outer area of the base and a total outer area of the side wall amounts to 25 to 35 percentages. The openings have a diameter of maximum 6 millimeters and are formed in circular, elliptical or polygonal shape. The base has a diameter of 20 centimeters and a surface area of 315 square centimeters. The height of the side wall corresponds to the diameter of the base with a difference of 10 percentages.
