Gas Conduit Extension for Pre-Mix Temperature Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature measurement systems in gas processing components fail to accurately measure the temperature of gases before they mix, as they do not account for thermal deformation of conduits, leading to potential damage and inaccurate readings.
Innovation Solution
A temperature measurement system with a gas conduit extension and an expansion opening that accommodates thermal deformation, allowing the temperature sensor to remain stable and measure gas temperature before mixing, using a thermowell or elongated shaft with a cover to prevent gas ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional temperature measurement system is used in a gas processing component, then the system structure is simple, but the temperature measurement accuracy deteriorates due to thermal deformation of conduits
Solution Approach 1:
The gas conduit is divided into two separate components: the main gas conduit and a separate gas conduit extension. This segmentation allows the extension to be specifically designed with thermal expansion accommodation features while the main conduit maintains its structural integrity for gas flow.
Solution Approach 2:
The gas conduit extension incorporates an expansion opening that allows dynamic adjustment to thermal deformation. The extension can expand or contract with temperature changes while maintaining proper positioning of the temperature sensor through the expansion opening.
2Reliability
If the temperature sensor is positioned directly in the gas conduit, then the measurement is direct, but the sensor is damaged by thermal deformation of the conduit
Solution Approach 1:
The gas conduit extension acts as an intermediary component between the gas conduit and the temperature sensor. It provides a protected pathway for the sensor while accommodating thermal deformation through the expansion opening, preventing direct contact between the sensor and the deforming conduit walls.
3Productivity
If the gas conduit extends into the mixing section, then gas flow is maintained, but thermal deformation affects temperature measurement accuracy
Solution Approach 1:
The gas conduit is segmented into the main conduit and an extension portion. The extension is specifically designed with an expansion opening that accommodates thermal deformation, allowing the gas flow to continue uninterrupted while the temperature sensor remains protected from measurement errors caused by conduit deformation.

AI summary
Systems and related methods including a gas processing component, a gas conduit extension, and a temperature measurement device. The gas processing component includes a mixing section where a first gas flow mixes with a second gas flow, and a gas conduit extension mounted at an outlet of the gas conduit having a gas conduit internal passageway for carrying the first gas flow to the mixing section. The gas conduit extension includes an internal passageway extension in fluid communication with the gas conduit internal passageway and an expansion opening extending from exterior of the gas conduit extension to the internal passageway extension. The temperature measurement device includes an elongated portion extending through the expansion opening into the internal passageway extension, and a temperature sensor inside the elongated portion located in the internal passageway extension to measure a temperature of the first gas flow prior to mixing with the second gas flow.
