What does the infrared scanner in a boiler system contain?

An infrared scanner in a boiler system typically contains a lead sulphide cell. This type of cell is particularly effective for detecting and measuring the infrared radiation emitted from objects, which is critical in monitoring temperature variations and ensuring the efficient operation of the boiler. The lead sulphide cell has good sensitivity in the infrared spectrum, making it suitable for applications where accurate temperature readings are essential, such as in the combustion processes within a boiler.

This sensitivity allows operators to detect fluctuations in temperature that may indicate issues with combustion or heat transfer, enabling timely adjustments that promote safety and efficiency. The ability of lead sulphide cells to respond to infrared radiation is specifically beneficial in environments like boiler systems where high temperatures can significantly affect system performance. Thus, the role of the lead sulphide cell in the infrared scanner is crucial for effective monitoring and management of boiler operations.
