. The Street railway journal . RAILWAY JOURNAL. [Vol. XXV. No. 7. LA system for heating and regulating boiler; FEED-WATER Among the new problems and opportunities presented by therecent commercial development of the steam turbine is the ap-plication of the auxiliary equipment in plants operated by tur-bines. The Harrison Safety Boiler Works, of Philadelphia,Pa., manufacturers of the well-known Cochrane feed-waterheaters, have paid special attention to the adaptation of theseheaters to such plants (the actual and contemplated installa-tions of Cochrane heaters in connection with steam turbinesalready exceeding 25,000 hp) and have developed some featureswhich should prove of considerable interest to engineers. The accompanying illustration shows a method patented bythe Harrison Safety Boiler Works for heating and regulatingthe boiler feed-water, and is particularly adapted to plantswhere steam turbines are operated in connection with sur-face condensers, although this method is also applicable to Pipe from Boiler ZD. PLAN OF PIPING FROM STEAM TURBINE AND ITS AUXILIARIES TO FEED-WATER HEATER plants where surface condensers are used in connection withreciprocating engines. Steam from the boiler enters the turbine through the upperpipe, the exhaust passing to the condenser. The pump belowthe condenser takes cold water through a suction pipe com-ing from the left and forces it into the condenser to liquefythe exhaust steam therein, the circulating water being dis-charged finally through the bend at the lower end of the con-denser. The condensation of the steam is drawn from thecondenser through its lowest horizontal connecting pipe by anauxiliary engine and pump and is delivered to the open feed-water heater. Another connection to the open heater consistsof the joined exhaust piping from the various pumps andsmall engines, the combined exhausts first passing throughthe oil separator of the heater. The feed-water from theheater is taken through the vertical pipe connected
