Here's a plant that carries the idea a step farther and guarantees its basic energy needs with largescale storage and handling facilities for both coal and oil Sy PHILIP KRONOWITT, Anijtont GrAtraf Moftoger, Cbo States, Ltd. The chemical-process industries, like all other industrials, find that power services play a continually greater part in final production cost. When our com pany decided on the new Toms River, N. J. plant, we mode every effort to put this condition to greatest advantage. Further, our equipment selection and arrangement point up a desire for flex ibility at vital points of the power cycle. Power-service needs at Toms River run the gamut. They include (1) steam for heating s group of nine building! in the center of a 1200-acre tract, for chemical-process kettle heating, drying and distillations (2) electric energy for lights, motors, relays, end so on (3) refrigeration for chemical-process cool ing (4) air conditioning for offices, lab oratories, first aid and cafeteria (5) compressed air for transfer of liquids from one vessel to another end for pres sure filtrations (6) inert gas for the transfer of flammable solvents (7) Dowtherm heating for processes that need high temperatures (8) sewagetreatment for purification of oil industrial i sanitary sewage before disposal. Sfaom Sendee. Our boilcrhouse, pbfrjjj to, above, is a first-rate example of h we planned for ample service facilities]! with the added advantage of flexibility# We picked two SO.OOO-lb-per-hr, 500-V$ psi-design-pressure, wotertube boilerta with walerwoJJj for pulverized coaJ t oil firing. These units are semioutdaoiS with firing aisle, pump room, forced-fl draft fans within the building ond boila|j casing,, induced-draft fans outside.

But we've Mj! a background of successful pulverised-* installations in other plants, and wetf anticipate no trouble on this score. j Should plant growth require-'addilionil.^ boilers we'll go to units double the sbeJ of the present ones ond more within the normal pulverized-coal range. Moreover, pulverised firing offers the, t solid-fuel system most readily adaptsbls ? to change-over for oil burning.
