The boilers will be of the well-known inclined water-tubetype of the Babcock & Wilcox Company, and will be equippedwith the new Babcock & Wilcox single superheaters. Thestation is designed for thirty-six boilers upon each boiler floor,or seventy-two in all, although for the initial installation onlythirty-six will be installed, together with two stacks. Eachboiler unit will be of 650-hp capacity, designed to deliversteam at 200 lbs. pressure and with a superheat of 100 degs.F. above saturation. Each boiler consists of three 42-in. steamdrums and has 294 tubes, 4 in. O. D. by 18 ft. long, arranged21 tubes wide and 14 tubes high, thus presenting a total heat-ing surface of about 6500 sq. ft.
