Patent No. EP4182622 (titled "Parallel-Flow Regenerative Shaft Kiln And Method For Burning Carbonate Rock") was filed by Maerz Ofenbau on Apr 25, 2022. The application was issued on Nov 1, 2023.

Patent Summary

A cocurrent-countercurrent regenerative shaft furnace for firing and cooling carbonate rocks, comprising two shafts operated alternately as a combustion shaft and a regenerative shaft, connected by a material-free channel. The furnace introduces exhaust gas into the combustion shaft's preheating zone or the connecting channel, and heats the exhaust gas to 900-1100°C before introducing it into the shaft. The furnace also includes a heat exchanger for heating the exhaust gas using cooling gas from the regenerative shaft, and a cooling gas extraction device for removing cooling gas from the shaft.
