New Electrical Plant.

The recently completed freezing works of the Canterbury Frozen Meat Co., Ltd., at Pareora. Timaru, have been equipped with a complete plant for driving all auxiliary machinery by electricity, in addition to being electrically lighted throughout. The generating plant for this purpose is steam driven, steam at i6olb. pressure being supplied by Stirling water- tube boilers. A 130 kilowatt Crompton multipolar dynamo is direct coupled to a two-crank Belhss and Morcom compound engine, the speed of the combined set being 425 revolutions per minute. The combined efficiency of the set on actual test is 87 per cent., the consumption of water per kilowatt-hour being 281b. condensing. The electrical system is direct current, 220 volts, for the supply of both motors and lighting. There are thirteen Crompton motors installed for driving the various machines employed in dealing with the by-products, ranging from 5 to 25-h.p. each. The whole of the plant was supplied by Messrs. A. & T. Burt, Ltd., to the specifications of Mr. B. W. Glass, the company's chief engineer. An almost similar plant has been supplied by Messrs. A. & T. Burt, Ltd., for th? Belfast 'ivovks of the same company. Both plants are now in operation and at v jiving full satisfaction. Extended tests have shown the marked economy of the electrical system compared with the older method of driving the auxiliary machinery by independent steam engines, or other means.
