Tours of the plant on Friday, June 11, will begin at 6 p.m. and continue until about 8 p.m.

when dedicatory exercises will be held at which Governor Pyle will be the principal speaker. Many prominent citizens have been invited to this dedication. After the dedication more guided tours of the plant will be conducted.

In order to retain the maximum amount of already heated air, which greatly conserves fuel resulting in increased efficiency, two air pre-heaters are inserted in the ducts of these four fans.

These air heaters are constructed with re-generative type rotating vertical flow elements. One-half of the diameter of the rotating elements is exposed in each duct. As the hot g-as or air passes toward the induced draft fans, the regenerative elements pick up to their respective heat capacity in the induced draft fan duct, and the rotating heated elements then transfer into the forced air duct where the incoming air is pre- TTf' Pli Pirn ct Eugene Shively, 3224 E.

TO CORRECT THIS, the initial boiler water, supplied from the servicewater system, is softened by a hot lime soda process. This reactor has a make-up rate, if necessary, of 3,200 gallons of softened water an hour. In the process of softening, gass such as oxygen, carbon dioxide and nitrogen are vented to the atmosphere.

IhlS IS important to the result ing economy of the power generated because here the plant starts with so manv cubic feet of iricai energ Functionally the boilers of both units perform the same task of generating steam.

The source of water for both boilers stems from the same system. In view of the fact that the boiler for Unit No. 2 is more spectacular and generates steam at higher pressure and temperature than the No. 1 unit, it might be interesting to describe its features. The boiler structure stands 103 feet high, contains an estimated 10 miles of steel tubing inside the insulated outer cover and will enerate 642,000 pounds of steam per I1UUI tXL square inch pressure at aoo degrees Fahrenheit.

In order to control combustion and steam generation, two forced draft fans of 206,000 cubic feet per minute total capacity, each directly connected to a 200 horsepower electric motor start a controlled movement of air through the boiler, thus carrying the heat from the ignited fuel on its way in and around the steam generating tubes as directed by internal baffling. The induced draft fans of 324,000 cubic feet per minute total capacity, each directly connected to a 230 horse helps win the race and overtime CORP. in building Plant, Unit No. 49k I wM We are proud to have been able to furnish the Salt River Power District's New Kyrene Steam Plant with Chicago Pneumatic Tool Company's Brandow Directs Engineering Safety Plan Cuts Injuries Air Compressors and other Industrial Tools lineman, cable splicer, and estimator for the Southern California iidison Co. from 1936 through 1947.

Four years of World War II service interrupted his utility career during which time he reached the rank of lieutenant commander in the U.S. Navy. Prior to joining the Salt River Power District in July 1949 as superintendent' of power, Brandow was the planning superintendent of the Canadian Corn-stock Company of St. Catherines, Ontario, Canada, between 1947 and 1949. WEST1 The Salt River Power District's safety program paid off by reduc-; ing injury and hardship to its employes and by raising the overall performance and efficiency of the work personnel.

In our Kyrene No.

2 plant we not only have the many splendid modern features of the Unit No. 1 plant, but have incorporated many and diversified improvements. Therefore we are certain that Kyrene No. 2 will be one of the most efficient operating plants in the country today. "These two units have been centrally located in the power district's system in order to better insure a constant and adequate distribution of power to the homes, businesses, farms, and industrial plants in the Valley of the Sun."

Brandow, assistant manager in charge of engineer ing, supply, construction, and ations of the Salt River Power District has a warm place in his heart toward the new Kyrene Steam Power Plant. "Kyrene No. is the first outdoor steam generating unit in Arizona and one of the first Brandow such plants in the West," Brandow said.

"The demonstrated efficiency of its centralized control is a tribute i to the engineering design which jwent into this plant. It is liter ally an operator's dream in action." A practical man. Brandow always foresees greater progress. "Just as in building a house, one Labor Unions Given Credit Due greatly to the splendid efforts of various construction unions, Unit No. 2 of the Kyrene Steam Power Plant was completed on schedule.

Co-operaflon between union heads, the union's skilled craftsmen, and the builders was outstanding and no work stoppages occurred as a result. Altogether about 750,000 man hours were consumed in build-in Units 1 and 2 of the plant. Unions involved in the construction, of Unit 2 plant included Local 627; Carpenters, Local 1089; Electricians, Local 640; Ironworkers.
