  • Apparatus and method for continuous measurement of the wet bulb temperature of a flue gas stream
    Patent number: 5460041
    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.

  • Method for metal halide removal
    Patent number: 4544379
    Abstract: A method for removing metal halides from effluent gas streams employs a rotary spray scrubber including an elongate gas flow duct and a rotary scrubber dispersion hub. The rotary spray scrubber is characterized by a ratio of hub diameter to duct diameter in the range from about 0.55 to 0.75. Using a basic liquid scrubbing medium in such a scrubber, metal halide particulate and hydrochloric acid gas removal efficiencies in excess of 99% have been achieved.
