Chat PAPER MIU EXPANDS Continued mg the reel of the time the condenser runt it minimum load. The average condenser load, in fact, amounti to only 2000 kw.. -What's more, our loading plant call (or turbine operation only when bad* supplied at the 30-psi-extraetion level are available. So we picked a condenoer to meet capacity under a 4-in. vacuum at full load. Two-half* capacity circulating-water pumpi and two half-copocity condensate pump* complete the major condenser auxiliar ies. Theio sixes, we lelt, would save power under hlgh-extraction conditions. Electrical Equipment. While we defi nitely tied turbine tile to our Nekoosa plant's steam needs we still had the problem ol filling this 6000-kw source oi electric energy into a 2-plant gyatem, which up-to then totaled 13,000 kw. We itarted with an intensive review of elec trical connections between the plinit. They lie together through a 15-kw system originating at the Ceniralia, Wig. 3600-kw hydro station and Unking up with hydro and steam plants of Pori Edwards and Nekoosa. The new 6000* kw unit exceeded the existing interrupt ing capacity at most of these locations, and particularly at Nekoosa. So here again a complete revision took place. A new outdoor 7500-kvn 3-phase trans former went In between the iS-kv line and the turbine room. We split the existing 480-v distribution bus to add aalety to the older switchgear and put in a new 2000-kva, 3-phase, 13,000- to 480-v transformer. Then 15-kv metalclad air-break awitchgear were supplied for the new transformers as well as lor the older 15-kv to 480-v and 15-kv to 2300-v transformers. All were rated at 300-mva Interrupting capacity, which is ample for a long time <o come. A new 2300-v distribution center in the turbine room supplies the boiler room, and the new paper-miehbo pacity. (t lies back through the ~ kva transformers in the old system, feed arrangement wso considered to stability to the system, ol parti' importance to the new paper mi in any plant didfreuities.

Their effeeJivenew as lubricants ia reduced by hot locations. These make heavy-bodied oils ibinnet, tend to evaporate the re quired moisture content of (I) soluble cutting oi), leaving behind a jelly-like mass |2) cerieln greases where oil sep arates out from the sosp. Cold areas, on the other hand, make lubricating oils and greases more dif ficult to handle- The oils flow mote slowly, &nd the greases become stiffen Oils containing fatty materials congeal them'out of solution under low-tempera* lure conditions. In addition, soluble oils, cold enough to freexa their mois ture content, prove useless. Somewhat along (ho lines of tempera ture effect Is spoilage In long storage. Soluble culling oils suffer most from this cause through a loss of moisture, But preventing this toss is more a prob lem of stock control than of storage or handling. Contamination. An improperly pro tected lubricant supply Is almost certain to experience dust end dirt contamina tion. No plant man worthy of the name - needs to have pointed out to him'the dangers of dirt in lubricating oils ond greases. Motoure contamination Is a major problem, too. Oils are more likely to be contaminated than greases. Some Are Storage and Handling... oils are designed to function as a lu bricating emulsion In the presence of moisture, or even small amounts of , water, but water contamination during ON LUBES storage can render them uaeleas for later service. This holds true for most steam-cylinder oils and similar ones meant for duties like lubricating the bearings of (he wet ends oi paper ma chines.

Fr example, exposure to Binomial temperatures or contamina tion from moisture or dirt--two ttrong possibilities--can bring on leakage or produce deterioration tbxt destroys a lubricant's suitability. We'll see why later. Of course, careless handling of the containers themielvea moy result in dents end split seams that take their loll in direct loss. Here are some simple rules fot storage and handlingAbnormal Temporotvi*. Both oils and greases experience considerable change heat-treating oils suffer complete de struction if contaminated by appreciable quantltea of water. Still another form of contamination develops. This Is the introduction or unwanted mixing of different oils when dispensing them within your plant. It stands to reason oils of different quail, ties when blended produce a third, en tirely new oil You must take certain precautions, and then exercise definite oare to keep original oils effective. ?js&ZiSu& s? a fMr on neat post/ ENGlNtMlHO AN0 MANAGEMENT SECTION
