High temperature camera system installed

Published:  11 September, 2007

Thermoteknix recently installed a new ThermaScope high temperature camera system for Puerto Rico Electric Power Authority (PREPA). PREPA's 900 MW Aguirre Power Plant, located in Salinas operates two heavy fuel fired boilers each containing 16 separate burners situated in the corners of the towers.

For PREPA, it was essential to see inside the boilers to optimise the combustion process to maximise efficiency and monitor safety. The company had previously used traditional video cameras from other manufacturers but due to flaws in design, these systems had had a tendency to overheat and burn out which is why the power company approached Thermoteknix" Puerto Rican agents LT Automation for a solution.

Thermoteknix’ ThermaScope SLK is a high temperature, fully radiometric thermal imaging camera that displays bright clear real time thermal images of high temperature processes and measures temperature at every point in the field of view. The camera is housed in a water cooled stainless steel unit with internal air cooling for the camera itself to purge the lens in order to provide clear imagery even in the most dusty of conditions.

ThermaScope also features a fail-safe retraction system which automatically pulls the camera back and away from the heat should either the air, water or power supply fail. The result is a rugged and reliable camera system which gives the process engineer or control room operator advanced viewing and analysis tools with control interface signals for closed loop control.

Thermoteknix mounted a ThermaScope boiler camera in each of the boilers at the top of each tower looking downwards over the burner zones. The cameras were networked to the control room to give PREPA’s engineers a crisp, real time display of the combustion process in each boiler and now have the added advantage of not only being able to monitor the process but actually measuring accurate temperatures within it.

PREPA also wanted to view normal video of the outside of each chimney stack simultaneously with the ThermaScope thermal image data in order to monitor smoke escaping from the boilers so a 'picture in picture’ view was also set up.
