<p>The furnace, which works according to the uniflow regenerative method, has two shafts (2, 3) which have, at the transition from the combustion zone (14) to the cooling zone (15), a widening which forms an internal shoulder (38) and at which the transfer of the combustion gases to the adjacent shaft (2, 3) takes place. This widened shaft region continues at least approximately cylindrically as far as the bottom-side bottom opening (35) of the shafts (2, 3), which is closed by an extraction device (34). This design of the shaft spaces, preferably together with an improved fuel distribution and charging device, makes possible, with satisfactory product quality, the burning of limestone with a grain size range of 10 to 30 mm. <IMAGE></p> |
