Abstract
An apparatus and method for measuring the wet and dry bulb temperatures of a hot flue gas stream containing fly ash and particulates by providing a sample sheath (12) in a gas duct (10) with a dry bulb sensor (16) and a wet bulb sensor (18) located within the sample sheath (12). The sample sheath (12) includes a self-cleaning dust filter (14) which removes the ash and particulates from the flue gas stream and a self-regulating water reservoir (26, 28) to continuously supply water for the wet bulb sensor (18).
