Abstract
A combustion system with a combustion area in a boiler including a fuel pipe for delivering fuel is disclosed. A duct having a bend extended there through is in fluid communication with the fuel pipe and the combustion area of the boiler. The duct has an outer perimeter and an inner perimeter. The duct includes a first partition plate to form a first parallel flow of the fuel between the outer perimeter and the first partition plate, upstream of the bend.

A system for providing combustion in a boiler having a combustion area comprising:
- a fuel pipe operable to deliver fuel;
- a duct with an outer perimeter having a bend extended there through, the duct being in fluid communication with the fuel pipe and the combustion area of the boiler;
- wherein the duct comprises:
- a first partition plate disposed in the duct to form a first parallel flow of the fuel between the outer perimeter and the first partition plate, upstream of the bend, and
- a first concentric conduit, positioned in the duct downstream of the bend, to deliver a first concentric flow of the fuel for combustion, wherein the bend between the first partition plate and the first concentric conduit is configured to transition the first parallel flow of the fuel into the first concentric flow of the fuel.
