A method is provided for heating a gas in a regenerator with a heat accumulation mass consisting of a loose bulk material arranged in a ring between two coaxial cylindrical grids, a hot collection chamber, surrounded by the inner hot grid, for the hot gases and a cold collection chamber, enclosed between the outer cold grid, on the one hand, and the wall of the regenerator, on the other hand, for the cold gases, wherein the increase in the head loss during the heating phase is at least 5 times as great as the product rho .g.H, in which H is the height of the regenerator, rho is the density of the gas at a temperature of 20 DEG C. and g is the acceleration due to gravity, and the gas flow rate is at least equal to 300 m3N/h.m2 of surface area of the hot grid at standard pressure.
