The standards for the quality of feed water and boiler water, which have been accepted by the instructions for servicing of KVG-25 and KVG-34 boilers, which are installed on the LENINSKIY KOMSOMOL and PEKIN class of ships should be changed these standards should take into consideration the operation of these ships by the Black Sea Agency and the conducted thermal-chemical tests. As a result, the salinity of the feed water should be decreased from 6 to 1 mgkg Cl and the boiler water from 0-275 to 0-50 mgkg, and at most, up to 0-180 mgkg Cl the alkaline number of boiler water should be decreased from 11-100 to 10-50 mgkg NaOH. Under normal operating conditiions, the drainage of the boiler should constitute 0.2-0.5 instead of the previously established 2. The salt content in the saturated steam should not exceed 0.1 mgkg.
