Oil in boiler feedwater is widely recognised as a potential danger. The older boilers suffered from foaming, priming and some loss of fuel economy. Newer higher rated equipment, though, can find the oil carbonising and this could produce tube-bagging or burn out. The Maritime Commission early in World War II substituted Uniflow en gines for turbines for the moio propul sion of several ships, namely the CVE's, LSD's and deep sea tugs of the Navy. A study was made of the various filters suitable for oil removal. Two diatomite filters, absorber and stripper types, were eventually chosen. The absorber removes the oil in a single process and the stripper uses a thin layer of diatomito to break any oil emulsion and then lets a mechanical separator remove the coelosced oit. But the Maritime Commission found the ab sorber or body feed system to be the most effective. Oil removal by this means Is effected over a wide range of temperatures (pre ferred 120-180 F) with costs consid ered reasonable by the author. ESIPP Paper. No number. BORDEN METAL PRODUCTS CO.

Straub and larion back In 1932 showed that decomposition of the car bonate and bicarbonate sails normally found in natural water for feedwater use was a function of operating pres sures between the range of 150-1500 psi. The author's investigation shows that the same condition holds, only more so, for the pressure range from 15-100 psi. As an example the rate of decomposition at 15 psi (250 F) is only half, that at 100 psi (338 F). .
