Abstract
According to one aspect of the invention, a turbine combustor includes an outer member coupled to a wall of the combustor, wherein there is at least one damping hole formed in outer member. The turbine combustor further includes at least one temperature control hole formed in the wall wherein the at least one temperature control hole is formed at an angle with respect to a line perpendicular to a hot gas path in the combustor.
Claims20
A turbine combustor comprising:
- an outer member coupled to a wall of the combustor, wherein there is at least one damping hole formed in the outer member;
- and
- at least one temperature control hole formed in the wall wherein the at least one temperature control hole is formed at an angle with respect to a line perpendicular to a hot gas path in the combustor.
An apparatus for damping and controlling a temperature of a portion of a combustor, the apparatus comprising:
- an outer member coupled to a wall of a combustor part, at least one damping hole formed in the outer member for damping and receiving a treatment fluid, thereby forming a resonator cavity;
- at least one temperature control hole formed in the wall, wherein the temperature control hole is configured to direct the treatment fluid from the resonator cavity toward a hot gas path inside the wall of the combustor part;
- and
- at least one member formed on an inner side of the wall and proximate the at least one temperature control hole, the at least one member configured to direct the treatment fluid along the inner side of the wall.
A method for temperature control and damping a portion of a combustor, the method comprising:
- flowing a treatment fluid through at least one damping hole in an outer member coupled to a wall of the combustor, wherein the outer member forms a resonator cavity that receives the treatment fluid;
- and
- flowing the treatment fluid from the resonator cavity through at least one temperature control hole formed in the wall, wherein the at least one temperature control hole is formed at an angle with respect to a line perpendicular to a hot gas path in the combustor.
