System for heating an air intake of turbine engine
View Patent ↗A heating system for a turbine engine air intake region for preventing the formation of ice on the air intake region, which may be formed from the bell-mouth, one or more vanes, such as inlet guide vanes, a turbine blade assembly formed from one or more blades, such as the first row of rotating blades, and related components. A heat source may be attached to the inlet manifold and positioned to emit thermal radiation toward the air intake region to prevent the formation of ice thereon.
1. A heating system for an air intake region of a turbine engine, comprising:
a turbine engine inlet manifold having a surface for directing air towards the air intake region; and
a plurality of heat sources affixed to the turbine engine inlet manifold, intermittently spaced circumferentially around the inlet manifold, and the heat sources positioned to emit thermal radiation towards the air intake region;
wherein the heat source emits thermal radiation to heat at least a portion of the air intake region to prevent the formation of ice on components forming the air intake region.
2. The heating system according to claim 1 , further including a recess in the inlet manifold in which the heat source is embedded.
3. The heating system according to claim 2 , wherein the heat source is an infrared lamp.
4. The heating system according to claim 1 , further including a plurality of recesses in the inlet manifold, wherein a heat source is embedded in a recess.
5. The heating system according to claim 4 , wherein the plurality of heat sources are positioned circumferentially wound the inlet manifold.
6. The heating system according to claim 5 , wherein the plurality of heat sources are infrared lamps.
7. The heating system according to claim 1 , wherein the turbine engine inlet manifold has a conical section with a plurality of recesses in which a plurality of heat sources are embedded.
8. The heating system according to claim 7 , wherein the heat sources are positioned circumferentially around the conical section.
9. The heating system according to claim 8 , wherein the heat sources are infrared lamps.
10. A heating system for an air intake region of a turbine engine, comprising:
a turbine engine inlet manifold with a conical section converging towards a compressor blade assembly and arranged to direct air toward a convergence region of the conical section;
a recess in the turbine engine inlet manifold; and
a heat source embedded in the recess and positioned to emit thermal radiation towards the air intake region;
wherein the heat source emits thermal radiation to heat at least a portion of the air intake region to prevent the formation of ice on the components of the air intake region.
11. The heating system according to claim 10 , wherein the heat sources embedded in the recesses are positioned circumferentially around the conical section.
12. The heating system according to claim 11 , wherein the heat sources are infrared lamps.
13. A heating system for an air intake region of a turbine engine, comprising:
a turbine engine inlet manifold having a surface for directing air towards the air intake region;
at least one heat source affixed to the turbine engine inlet manifold and positioned to emit thermal radiation towards the air intake region; and
a recess in the inlet manifold in which the heat source is embedded,
wherein the heat source emits thermal radiation to heat at least a portion of the air intake region to prevent the formation of ice on components forming the air intake region.
