Kiln And Method For Burning Carbonate Rock
Patent No. EP4430010 (titled "Kiln And Method For Burning Carbonate Rock") was filed by Maerz Ofenbau on Jan 30, 2024. The application was issued on Mar 12, 2025.
Patent Summary
A method for firing materials, such as carbonate rocks, utilizes a co-current counter-current regenerative shaft kiln comprising two shafts connected by a channel and operated alternately as firing and regenerative shafts. Material flows through a preheating zone, a firing zone, and a cooling zone. Cooling gas enters the cooling zone, while exhaust gas exits a shaft via an outlet located within or above the preheating zone. This exhaust gas is branched into two parts: a first part fed to the preheating zone's upper region via a first inlet, and a second part fed to the preheating zone via a second inlet located downstream of the first. Optional embodiments include compressing, heating, or adding oxidants to the exhaust gas.
