Results Obtained by Electrical Method.—The apparatus as de-scribed has been used to determine the dew-point of the furnace gasesat two large central power stations. In both cases the boilers wereabout 1700 , and were equipped with economizers and evaporation varied from 100 000 to 150 000 lb. per hr. duringthe day to 30 000 to 50 000 at night. Both boilers were stoker one case the coal used had an average sulphur content of percent, whereas in the other case the average sulphur content was (as fired basis). The points of sampling were between the economizersand preheaters at the middle of the setting. The gas temperature atthis point was 150-170 deg. C. (300-350 deg. F.). A continuous flowof flue gases through the apparatus was brought about by an airaspirator. Figures 5 and 6 show typical variations of the Wew-point with timefor the two plants.
