Abstract:
1. A hydrogen-rich gas combustion device, comprising a chamber, a cooling air sheath, a fuel sprayer, a vortex generator, an igniter and a vessel shell, wherein said chamber has a non-premixed air conduit inside; said chamber has an air distributor at an upstream end of said chamber corresponding to said non-premixed air conduit; and said chamber has a non-premixed fuel conduit at a side of said chamber; wherein said cooling air sheath is positioned at an opposite downstream end of said chamber; said cooling air sheath has a plurality of holes on a surrounding wall of said cooling air sheath; said cooling air sheath defines a combustion chamber inside; and said cooling air sheath has a first corresponding hole to accommodate said igniter; wherein said fuel sprayer is located in said chamber; and said fuel sprayer is connected with said non-premixed fuel conduit; wherein said vortex generator is positioned around said fuel sprayer; and said vortex generator defines a partially pre-mixing annulus downstream in an annular space between said fuel sprayer and said combustion chamber; wherein said igniter is located at a side of said cooling air sheath and is corresponding to said fuel sprayer; and wherein said vessel shell is sleeved outside around said chamber and said cooling air sheath to define a cooling air conduit in said vessel shell; and said vessel shell has a second corresponding hole to be connected with said non-premixed fuel conduit, wherein said chamber has an opening at said opposite downstream end of said chamber; said non-premixed fuel conduit is connected with said opening; and said fuel sprayer is located in said opening, wherein said chamber has a plurality of connecting holes around said opening of said chamber; said non-premixed air conduit is connected with said plurality of connecting holes; and said vortex generator is located downstream of said plurality of connecting holes opposite to said cooling air sheath.
