Method For Burning Fuel In A Cylindrical Combustion Chamber

Patent No. EP3475609 (titled "Method For Burning Fuel In A Cylindrical Combustion Chamber") was filed by Lhoist Recherche ET Dveloppement on Jun 28, 2017. The application was issued on Mar 9, 2022.

Patent Summary

A combustion process for a cylindrical combustion chamber that enables efficient combustion of pulverulent solid fuels in existing calcining furnaces. The process involves projecting a jet of pulverulent solid fuel into the combustion chamber using a burner, and surrounding the fuel jet with a stream of oxidizing gas that is recirculated from the furnace. The fuel jet is further promoted by partial or total rotation, achieved through rotational movement of the conveying air. This enables complete combustion of the fuel within the combustion chamber, eliminating the need for costly and complex modifications to the furnace.
