Abstract
The conventional gas turbine combustor is improved by mounting a pilot flame producing torch in a wall of the combustor to project a flame into the combustor as a means of ignition. The torch preferably is a catalytic igniter which will operate over a wide range of air/fuel ratios.
Claims5
A method of continuous ignition of a first fuel/air mixture comprised of a first fuel in a combustion chamber, which comprises:
- a) providing a tubular inlet into said combustion chamber;
- b) mixing a second fuel of the same composition as said first fuel with air in a tube whereby a second fuel/air mixture is formed, said tube connected to said tubular inlet;
- and
- c) continuously igniting said second fuel/air mixture in said tube by continuously passing a portion of said second fuel/air mixture over a heated, catalytic igniter element such that the combustion zone created thereby extends beyond said tubular inlet;
- whereby the resulting flame ignites said first fuel/air mixture in said combustion chamber.
