This tank should be provided with a water jacket, with steam connection to keep the water hot for the purpose of re-evaporating the liquid ammonia, the gas piped back to the suction side of the compressor. In this way the tank serves the double purpose of converting the liquid from the separator into a gas and purifying the ammonia by separating out the oil or water that may have been taken into the system by leaks or inferior ammonia and the oil that works into the system from the compressor. When the liquid from the separate-is carried backto the evaporating coils, there is practically no loss from this source, as the liquid is re-evaporated and will do useful work in the transfer of heat, but the beneficial results of leading the separator drain to a purifier will more than offset the gain by the other method of re-evaporating the liquid in the coils. Another system for removing liquid from the separator is to connect the drain line to an automatic drip tank and pump which is operated with a float and returns the liquid to the expansion or evaporating coils, the operation being the same as that of a pump and receiver used in a steam plant for returning condensate to the boiler.

F. for bathhouse purposes, the water to be heated in a 500-gal. open tank, using steam at 90 lb. gage pressure? How much steam would be required? J. T. C. A simple method of heating water in an open tank is to employ an iron-pipe steam coil like a wall corner coil, placing one side of the coil about 6 in. above the bottom of the tank and the other side vertical.
