Steam Turbine Explosion at Chillicothe, Ohio. THERE IS Worthwhile Information FOR YOUR ENGINEER IN THIS MAGAZINE. PLEASE LET HIM SEE IT. 162 THE LOCOMOTIVE. [April, Steam Turbine Explosion at Chillioothe, Ohio. THE disruption of a disk in the third stage on the rotor of a three,000kw. turbine Friday morning, August 20th, 1926, at the plant ofthe Mead Pulp and Paper Organization, Chillicothe, Ohio, resulted ina property loss of ,000 not counting the use and occupancy loss.Two guys have been injured, but fortunately their injuries had been not seriousdespite the fact that 1 of the males at the time of the accident wasstanding beside the machine that exploded. A view of the turbine afterthe explosion is shown on the front cover. The home harm was heavy but was confined practically entirelyto the turbo-generator unit itself. The steam finish of the unit was acomplete loss, and in addition considerable harm was accomplished to theelectric generator. The bell end of the generator casing was cracked,the shaft sprung,

ALTERNATING-Existing MACHINERY 175 Curtis Turbo-Alternator. A general view of a Curtis steam tur-bine alternator, constructed by the Common Electric Firm, is shownin Fig. 183. This unit is rated at 5,000 kilowatts, 13,000 volts,25 cycles, and 750 revolutions per minute. As is usual with Curtisturbo-alternators of big size, this is of the vertical type. Thegenerator is positioned at the leading of the unit and the turbine wheels

Fig. 184. Two Views of Stationary Armature of Curtis Alternator are below. The stationary armature with the clamping devices forrigidly supporting the coils is shown in Fig. 184. Fig. 185 is a view of a smooth core rotor for a 9,000-kilowattvertical variety of Curtis turbo-alternator. A function of interest isthe strategy employed for the attachment of the shields for the endwindings. The outer retaining cylinders are secured to the innershell by a huge quantity of short bolts which eliminate a portion of thestress of the end windings from the outer shell. The rotor is so 187 176 ALTERNATING-Existing MACHINERY designed that it acts as a powerful fan, forcing air throughout theparts of the generator requiring ventilation. The positive aspects claimed for the vertical shaft sort of Curtisturbine for large machines are: (1) The relative positions of revolving and stationary parts are definitelyfixed by the step-bearing. (two) The stationary portion is symmetrical, and cost-free from distortion by heat. (three) The shaft
