Abstract
An unburned carbon and other combustibles monitoring and control system for a fossil-fueled boiler, such as a pulverized coal fired boiler. An infrared imaging camera counts the moving hot particles entrained in the hot gases exiting the boiler and provides a first signal representative of the number of hot particles in the hot gases over a predetermined period of time. A signal processor is connected to the infrared imaging camera for counting the hot particles for receiving the signal representative of the number of particles in the hot gases and providing a second signal representative of the unburned carbon and other combustibles content of the fly ash produced by the boiler. In the preferred embodiment, the apparatus includes at least one air/fuel control element for controlling the air/fuel ratio of the fossil-fueled boiler and a control system connected to the control element for receiving the second signal representative of the unburned carbon and other combustibles content of the fly ash produced by the boiler and a predetermined set point for the unburned carbon and other combustibles content of the fly ash produced by the boiler, the control system being operable to adjust the air/fuel control element in response to the second signal and the set point.
