COMPARAIVE TESTING FOR HEAT-RESISTANCE OF ANION EXCHANGE RESINS FOR CONDENSATE POLISHING[J]. Thermal power generation, 1997, (4): 38-41. DOI: 10.19666/j.rlfd.1997.04.009.
which have been used for condensate polishing in several power plants in China
were parallely determined. After suffering 240 hours constant temperature of 100℃
the total capacity of eight anion resins decreased by 10 to 15%
and the strong basic group decreased by l6 to 24%. The other two decreased even more
and one of the strong basic group decreased down over 40%. These data indicate that the heat-resistance of anion exchange resins which are intended to be used in a higher temperature condensate polishing system should be especially considered.
