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.
Claims18
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, the duct being in fluid communication with the fuel pipe and the combustion area of the boiler;
- wherein the duct comprises:
- a first planar partition plate disposed within and spanning the duct to form a first parallel flow of the fuel between the outer perimeter and the first partition plate, upstream of the bend;
- a first concentric conduit, positioned in the duct downstream of the bend, to deliver a first concentric flow of the fuel for combustion, the bend having a first portion configured to connect the first partition plate with the first concentric conduit wherein the bend is between the first partition plate and the first concentric conduit and is configured to transition the first parallel flow of the fuel into the first concentric flow of the fuel;
- a second planar partition plate, disposed within and spanning the duct, to form a second parallel flow of the fuel between the first partition plate and the second partition plate upstream of the bend;
- and
- a second concentric conduit, positioned in the duct downstream of the bend, to deliver a second concentric flow of the fuel for combustion, the bend having a second portion configured to connect the second partition plate with the second concentric conduit, wherein the bend is between the second partition plate and the second concentric conduit and is configured to transition the second parallel flow of the fuel into the second concentric flow of the fuel.
