Boiler Scale Formation And Control Subject Of Paper by Rivera It a recentpaper, "Concentrat ing Films: Their Hole in Boiler Scale and Corrosion Problems," H. M. Rivers, Director of Engi neering Service for Hall Labora tories, discusses the theory of how and why highly concentrated films form on steaming surfaces, the mechanism of steam generation and scale formation, characteristic effects of concontrating films, and problems associated with degree of fUm concentration. 'A Mr. Rivera points out? that water consultants are responsible for treating boiler water so that concentrating salts do not crystal lize out of solution, or precipitate in forms which will accumulate continuously as solid deposits. Further responsibility: natural constituents or added chemicals in boiler water must not give trouble because of decomposition or volatilization under "film" con ditions; and corrosive concentra tions of free caustic must be safely avoided. On the other hand, boiler makers must design for heat input rates which limit tendency toward excessive concentrations, and pro vide adequate circulation and tur bulence to assure rinsing of ail steaming surfaces.

Buswell, chief of Illinois State Water Survey, reported at the recent American Power Conference. Radar tracks the release of this water to land surface as rain from thunderstorms. Notonly arestorm paths logged, but the amount of rainfall can be estimated. Accumulation of such data pro vides a basis for future efforts to trap more rain.

To properly prepare this water, a flexible pre-treating system was recommended by Alex Henricks and approved by his associates on the Hall hoadquarters staff. Designed to insure good quality water under any conditions, the equipment suggested was simple to operate and sized so that ca pacity would be adequate re gardless of incoming water com position; yet frequent attention would not be required to keep the system in proper operation.
