A combustion system

The combustion system (1) comprises a furnace (2) with an enclosure (3) and burners (4a, 4b, 4c) having different elevation, a mill (6), a vapour separation system (7) for receiving a non-homogeneous flow of vapour and pulverized fuel and providing a fuel rich flow through first ducting (10) to burn...

More Information
Summary:The combustion system (1) comprises a furnace (2) with an enclosure (3) and burners (4a, 4b, 4c) having different elevation, a mill (6), a vapour separation system (7) for receiving a non-homogeneous flow of vapour and pulverized fuel and providing a fuel rich flow through first ducting (10) to burners (4a, 4b) having a lower elevation, and a fuel lean flow through second ducting (11) to burners (4c) having a higher elevation. The first ducting (10) comprises an impeller (12) at a position downstream the branching area (9). The impeller (12) defines a fuel concentrated content flow (FC) and a fuel reduced content flow (FR). The combustion system comprises also ducting (15) for supplying the fuel concentrated content flow (FC) to first burners (4a) and ducting (16) for supplying the fuel reduced content flow (FR) to second burners (4b). The second burners (4b) have a higher elevation than the first burners (4a).
