Abstract
The present invention discloses a combustor system and method of measuring impurities in the combustion system. The combustion system includes an up-stream fuel injection point; a down-stream turbine combustor; a flame zone in the turbine combustor comprising a plurality of axial sub-zones; an optical port assembly configured to obtain a non-axial, direct, optical view of at least one of the plurality of axial sub-zones, and an impurity detection system in optical communication with the optical port assembly.
Claims25
A combustor system, comprising:
- an up-stream fuel injection point;
- a down-stream turbine combustor;
- a flame zone in the turbine combustor comprising a plurality of axial sub-zones;
- an optical port assembly comprising a plurality of optical ports and configured to obtain a non-axial, direct, optical view of at least two of the plurality of axial sub-zones, wherein at least one of the plurality of optical ports is aligned to have an oblique angle view of the flame zone;
- and
- an impurity detection system in optical communication with the optical port assembly.
A combustor system, comprising:
- an up-stream fuel injection point;
- a down-stream turbine combustor;
- a flame zone in the turbine combustor comprising a plurality of axial sub-zones;
- an electrode assembly disposed at the vicinity of combustor system to excite the flame during operation;
- an optical port assembly comprising a plurality of optical ports and configured to obtain a direct optical view of at least two of the plurality of axial sub-zones, wherein at least one of the plurality of optical ports is aligned to have an oblique angle view of the flame zone;
- and
- an impurity detection system in optical communication with the optical port assembly.
A method of analyzing and measuring specific impurities in a combustor system, comprising:
- injecting a liquid fuel into a flame zone of the combustor system,
- generating a flame in the flame zone of the combustor system,
- increasing temperature of the flame by providing an external stimulation,
- coupling a direct emission signal of the flame from a plurality of axial subzones of the flame zone through an optical port assembly to a detector system, and
- analyzing the emission signal from the plurality of axial subzones to detect an impurity species present in the liquid fuel, wherein the optical port assembly comprises a plurality of optical ports and wherein at least one of the plurality of optical ports is aligned to have an oblique angle view of the flame zone.
