This basin is provided with a 4-in. centrifugaldredge pump belt-driven by a 10-hp motor, and is fittedwith three vertical wire mesh screens which are conven-iently handled by a pulley and chain hoist running on achannel iron mounted above the basin. The screen meshesare respectively 1 in., $4 hi. and y2 in. in size, and the con-densing intake and piping between the river and the planthave sufficient capacity to handle water for an ultimatainstallation of kw in steam generating the screen basin a pipe line runs under ground to the. Denver Power—Map of Platte Street Power Station Site boilers are provided with mechanical draft and short steelstacks for each unit. The steam is superheated from 50 to60 degrees Fahr. Lignite coal mined in Colorado is burnedsuccessfully by the stokers. The stokers for the thir-teen original boilers are operated by two 15-hp motors, andthose in the six new boilers are driven by a separate 15-hp motor. The early boiler installation discharged thesmoke into a steel stack 185 ft. high and 12 ft. in insidediameter, located near the southerly end of the plant. Theenlargement of the boiler plant required the provision ofthree supplementary stacks about 8 ft. in diameter and 10ft. high in the old boiler room section, while each of thesix new boilers is equipped with a steel smoke discharge 5ft. in diameter which projects 4 ft. above the roof. Condensing water for the station is drawn from thePlatte River. At the waters edge a concrete intake 78 x 25 ft.
