Abstract

System and method for continuously monitoring the wet bulb temperature in a flue gas stream, for example, at the inlet of a spray dryer. A sample of the flue gas is maintained at substantially the same moisture content and temperature as the gas in the flue. The temperature of this sample is measured with a sensor surrounded by a liquid absorbent wick which is immersed in liquid maintained at a substantially constant level.
