Description

Technical Field

[0001] This utility model relates to the field of combustion chamber monitoring technology, specifically to a combustion chamber flame stability monitoring device. Background Technology

[0002] Current methods for monitoring the flame stability of gas turbine combustors primarily rely on fixed optical sensor arrays or thermocouple assemblies, evenly distributed circumferentially around the combustor bushing. These devices use rigid supports to fix the sensor positions and monitor flame temperature distribution and flicker frequency under static conditions. However, they cannot dynamically track flame drift during operation. Furthermore, under high load and variable operating conditions, monitoring blind spots are easily created due to flame center shift. Therefore, we propose a new combustor flame stability monitoring device. Summary of the Invention

[0003] The purpose of this invention is to address the problem that using rigid brackets to fix the sensor position in gas turbine combustor flame stability monitoring, which monitors flame temperature distribution and flicker frequency under static conditions, is ineffective in dynamically tracking flame drift during operation. Furthermore, under high load and variable operating conditions, blind spots can easily arise due to flame center shift. This invention provides a combustor flame stability monitoring device.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A combustion chamber flame stability monitoring device includes a rotating ring seat. The center of the rotating ring seat is fixed to the combustion chamber flange end face by a large inner diameter bearing. Fixed bases are fixedly connected to both sides of the rotating ring seat. A detection head is fixedly connected to the upper end of the fixed base. A thermocouple sensor is provided on the side of the detection head facing the combustion chamber. A drive motor is provided on the lower side of the rotating ring seat, and a drive mechanism is provided on the lower side of the rotating ring seat.

[0006] Furthermore, a drive gear is fixedly connected to the output end of the drive motor, and an internal gear ring is fixedly connected to the outer edge of the bottom surface of the rotating ring seat, with the drive gear meshing with the internal gear ring.

[0007] Furthermore, a motor mounting bracket is fixedly connected to the outer side of the drive motor, and the inner end of the motor mounting bracket is welded and fixed to the outer wall of the combustion chamber.

[0008] Furthermore, a heat-conducting inner liner is fixedly connected to the inner wall of the slot on the inward side of the rotating ring seat, and a spiral heat exchange tube is spirally wound on the outer side of the heat-conducting inner liner.

[0009] Furthermore, a line pipe is fixedly connected to the center of the outer end of the detection head, and the signal transmission line of the thermocouple sensor and the gas supply line of the heat-conducting inner liner are both installed through the line pipe.

[0010] Furthermore, the detection head is fixedly connected to a high-temperature resistant transparent observation window on the side facing the combustion chamber, and the high-temperature resistant transparent observation window covers the slot on the inside of the rotating ring seat.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In use, the drive motor starts, driving the rotating ring seat to rotate via the drive mechanism, which in turn rotates the detection head to comprehensively monitor the flame stability within the combustion chamber. Thermocouple sensors collect temperature data from the combustion chamber in real time and transmit it to an external processor for analysis, further improving the accuracy and reliability of flame stability monitoring. During operation, the device automatically adjusts the angle and position of the detection head to ensure comprehensive and accurate monitoring of the flame in different areas of the combustion chamber, thereby effectively improving the operating efficiency and safety of the combustion chamber.

[0013] 2. This utility model achieves stable driving of the rotating ring seat by the drive motor through the meshing transmission of the drive gear and the internal gear ring, ensuring the smoothness and accuracy of the rotating ring seat during rotation. At the same time, this transmission method has a simple structure, is easy to maintain, and improves the overall reliability and service life of the device.

[0014] 3. This invention achieves effective thermal protection for the detection head through the design of a heat-conducting inner liner and a spiral heat exchange tube. The heat-conducting inner liner can quickly absorb and disperse the heat generated by the detection head, while the spiral heat exchange tube further enhances the heat transfer efficiency, ensuring that the detection head can still operate normally in high-temperature environments and extending its service life. At the same time, this thermal protection structure design also improves the overall thermal stability and safety of the device, providing a more reliable guarantee for flame stability monitoring.
