Abstract
In a flue gas scrubber for removing sulfur dioxide from flue gas and having a spray dryer vessel inlet duct defined by a duct wall, the apparatus may be used to measure in situ the wet bulb temperature of the flue gas in the dryer vessel inlet duct. A water nozzle and a temperature sensor are both located in the dryer vessel inlet duct. The nozzle sprays water on the sensor and the wet bulb temperature of the flue gas is continuously measured. The apparatus gathers wet bulb temperature data which may be used for process control or for determining whether a leak has occurred within the tubes of a coal-fired steam boiler.
