ABSTRACT:
Purity of boiler feedwater being the effluent of a condensate polishing plant in a steam power station is determined by a method in which some of the effluent is used as feedwater for an auxiliary boiler. The blow down from this boiler, which uses a much higher evaporation ratio than the main steam generator, is sampled and provides -- by measurement of its conductivity -- an indirect determination of condensate purity. With a condensate polishing plant consisting of more than two, e.g. three filter units, and with one filter unit shut down for regeneration one uses as feedwater for the auxiliary boiler effluent of that one of the other two filters which is nearest to its exhaustion state, i.e. the filter which has been in operation the longest at this time.
