Recent studies have been conducted to determine the major causes of steam powerplant failure. One such study, made by Timmons and Charks, marine consultants and water treatment specialists, has revealed that boilers are the most vulnerable part of the entire propulsion system and that the major source of boiler failure is due to the accumulation of deposits in boiler tubes. These deposits consist of 60-95 percent copper and iron oxides. Because chemical means of controlling the problem has proven impossible, Croll-Reynolds has developed a new feedwater filter that is very suitable for use in marine powerplants. The filter element is constructed of wire coated with a wood pulp derivative. This filter coating is biodegradable and the filter can be easily cleaned by backwashing and pumping the sludge overboard without fear of pollution. The filter is capable of removing particles in excess of 0.5 micrometer.
