EXPERIMENTAL DETERMINATION OF STEAM PURITY CHARACTERISTICS OF NAVAL BOILERS,
Abstract
Tests were conducted on the Laboratory's DLG-6 and DLG-9 boilers, NBTL Projects B-270 and B-271, to determine relations between moisture carryover, boiler water level, steaming rate, and boiler water dissolved solids concentration. Measurements made on the DLG-9 boiler utilized both conductivity and sodium tracer methods. Other tests of modified steam separators in the DLG-9 boiler, and of separators in other boilers at the Laboratory, have been conducted as a part of other related experimental programs. The procedure in conducting moisture tests consisted of steaming the boiler at the particular load of interest, treating the boiler water with NaCl to establish the desired values of total dissolved solids and chloride concentration, and adjusting the boiler drum water level while measuring the concentration of dissolved solids in sampled condensate of the output steam. Three principal methods were used for determining the carryover: conductivity measurement of conden04d steam as spectrophotometric measurement of the concentration of sodium ion, and analytical gravimetric analysis of total solids by evapora tion to dryness.
