Abstract

A boiler apparatus includes a housing defining an interior boiler chamber and a burner element arranged to be in thermal communication with the boiler chamber. An ignition device is provided for instigating combustion of an inlet gas stream, and is arranged adjacent one edge of the burner element. A gas restricting device is utilized for restricting contact between the burner element and the inlet gas stream such that the inlet gas stream is initially incident upon the one edge of the burner element, thereby forcing the inlet gas stream to propagate across the burner element from the one edge.

Independent Claims | See all claims (20)

  1. 1. A boiler apparatus comprising: a housing having an interior boiler chamber; an inlet manifold having an inlet aperture means formed therein, said inlet aperture means permitting flow of a boiler fluid in a first direction from said inlet manifold to said boiler chamber; a turning vane disposed adjacent said inlet aperture means, said turning vane diverting said boiler fluid in a second direction; a burner element arranged to be in thermal communication with said boiler chamber; a burner enclosure for presenting an inlet gas stream to said burner element via a gas inlet aperture; and a gas restricting means for restricting contact between said burner element and said inlet gas stream such that said inlet gas stream is initially incident upon one edge of said burner element, thereby forcing said inlet gas stream to propagate across said burner element from said one edge.
  2. 6. A boiler apparatus comprising: a housing defining an interior boiler chamber; an inlet manifold having an inlet aperture formed therein, said inlet aperture facilitating entry of a boiler fluid from said inlet manifold to said boiler chamber; a turning vane disposed adjacent said inlet aperture, said turning vane diverting said boiler fluid; a burner element arranged to be in thermal communication with said boiler chamber; an ignition device for instigating combustion of an inlet gas stream, said ignition device arranged adjacent one edge of said burner element; and a gas restricting means for restricting contact between said burner element and said inlet gas stream such that said inlet gas stream is initially incident upon said one edge of said burner element, thereby forcing said inlet gas stream to propagate across said burner element from said one edge.
  3. 9. A method of operating a boiler having a boiler chamber and an inlet flow of boiler fluid into said boiler chamber, said method comprising the steps of: directing said inlet flow of boiler fluid such that said boiler fluid flows adjacent an interior surface of said boiler; and arranging a structural support post in said boiler chamber, said support post extending between opposing walls of said boiler chamber.
  4. 13. A boiler apparatus comprising: a housing defining an interior boiler chamber; a burner element arranged to be in thermal communication with said boiler chamber; an ignition device for instigating combustion of an inlet gas stream, said ignition device arranged adjacent one edge of said burner element; and a gas restricting means for restricting contact between said burner element and said inlet gas stream such that said inlet gas stream is initially incident upon said one edge of said burner element, thereby forcing said inlet gas stream to propagate across said burner element from said one edge.
  5. 17. A boiler apparatus comprising: a housing defining an interior boiler chamber; a burner element arranged to be in thermal communication with said boiler chamber; an ignition device for instigating combustion of an inlet gas stream, said ignition device arranged adjacent one edge of said burner element; a gas restricting means for restricting contact between said burner element and said inlet gas stream such that said inlet gas stream is initially incident upon said one edge of said burner element, thereby forcing said inlet gas stream to propagate across said burner element from said one edge; an inlet manifold having an inlet aperture formed therein, said inlet aperture facilitating entry of a boiler fluid from said inlet manifold to said boiler chamber; and a turning vane disposed adjacent said inlet aperture, said turning vane diverting said boiler fluid such that said boiler fluid is caused to initially flow adjacent an interior surface of said boiler chamber.
  6. 19. A boiler apparatus comprising: a housing having an interior boiler chamber; an inlet manifold having an inlet aperture means formed therein, said inlet aperture means permitting flow of a boiler fluid in a first direction from said inlet manifold to said boiler chamber; a turning vane disposed adjacent said inlet aperture means, said turning vane diverting said boiler fluid in a second direction; and wherein said inlet aperture means comprises one of a plurality of discreet inlet holes, and an elongated inlet slot.
  7. 20. A method of operating a boiler having a boiler chamber and an inlet flow of boiler fluid into said boiler chamber, said method comprising the steps of: directing said inlet flow of boiler fluid such that said boiler fluid flows adjacent an interior surface of said boiler chamber; arranging a burner element to be in thermal communication with said boiler chamber; arranging an ignition device adjacent one edge of said burner element for instigating combustion of an inlet gas stream; and restricting contact between said burner element and said inlet gas stream via a gas restricting means such that said inlet gas stream is initially incident upon said one edge of said burner element, thereby forcing said inlet gas stream to propagate across said burner element from said one edge.
