At the Barstow 10MW Solar Thermal Pilot Plant, water is converted to high pressure steam by concentrated solar radiation. The design of the elements in which the boiling takes place makes them vulnerable to blockage by particulates contaminating the circulating water. Concern over the potential for heat damage to blocked boiler elements has led to the development of a remote optical monitoring system for use at the Pilot Plant. The system employs a telescope and infrared vidicon to detect the increased blackbody radiant emittance produced by an overheated element. An image is provided with spatial and thermal resolution sufficient to detect and identify a single blocked element. Design considerations for such a system are discussed, as are performance at the Pilot Plant and possible extensions of the system to more sophisticated pyrometric tasks.
