. The Street railway journal . with the reservoir. Above the reservoir is a steeltank giving a head of about 30 ft. for boiler washing andother purposes in the plant. Three 350-hp Stirling boilers are installed in the boilerroom in two batteries. Each has 3541 sq. ft. of heating sur-face and sq. ft. of grate surface. The flue gases arenormally passed into the stack through a Green economizerof 3840 sq. ft. of heating surface built up in thirty-two sec-tions of ten 4 9/16-in. tubes each. The stack is a Weber through the wall and dropped down to the turbine inletlevel in the turbine room. An auxiliary header 7 ins. indiameter is carried through the turbine room parallel to theboiler room wall, and this is cross connected at each endto the main header by a 6-in. line. The turbines are directconnected to three-phase, 2300-volt, 600-cycle generatorsmaking 1800 r. p. m. Each turbine exhausts into a line carried through the turbine room basementparallel to the boiler room wall and leading out of doors to. FLOOR FLAX GENERAL PLAN AND SECTIONAL ELEVATION OF POWER HOUSE OF THE JACKSON RAILWAY, LIGHT & POWER COMPANY reinforced concrete chimney 200 ft. high and 8 ft. insidediameter throughout its entire length. The boiler feedpumps are located in the basement of the turbine room, sur-rounded by a floor opening about 10 ft. x 15 ft. 6 ins. indimensions. These are duplex 9 in. x 6 in. x 12 in. Blakepumps, steam driven. The feed water heater is of theNational closed type, rated at 500-hp, and is located in acorner of the turbine room near the boiler room. From each boiler a 7-in. steam pipe is carried to a header located on the inside of the boiler room this header a 6-in. pipe for each turbine is carried an Alberger 2000-kw barometric jet condenser located closeto the chimney. The individual turbine exhaust pipes areeach 30 ins. in diameter. Each turbine is provided with ai2-in. atmospheric exhaust pipe discharging out of doorsthrough an i8-i
