Evap orator, not shown, receives steam from thfrd bleed point; vapor goes to deaerator gram below shows the relatively slant feed-heating cycle, Horizontal hotwiiii pumps discharge through the ir-ejecSI condenser and low-pressure (8-pt'ujl heater to the deaerator, which is plied from the eeeond bleed point, Si psla. Boiler-feed pumps (one tneioxL and one turbine-driven) take suction from the deaerator hotwell and A\Jt charge through intermediate and kigtij pressure heaters, which receive uej M from the third (1314 psht) and u fourth bleed points (300 psia), re spectively. An additional motor-drivtH feed pump urill be installed for Unfit No. 2. Pinol feedwater temperature*^ 400 F. Heaters are all horizontal; IdirJ pressure unit stands alongside the coal denser in the basement, intermedUtel end high-pressure units are in o eaten hay above the gage board and below thel evaporator and ,the direct-contact triyil type deaerator. :jf A horizontal single-effect evaporaufl receives steam from the third bl point (131.5 psio), and vapor du, charges directly to the deaerator. Rag water for makeup, which coma from deep wells, is softened by hydrogen zeolite and sodium-zeolite units, wiiM. degasifier,'located in the ooal-cqarma junction tower to the north of the pla Phosphate and sulphite for !nteh_ treatment are fed to the drums by sij] juqlablo-etroko proportioning purnpsV Condenser, Auxiliaries. The 2-psgl vided-wnterbox condenser, across-tbt. turbine axis, is fitted with Admirslm tubes and a twin-element 2-stage steam! jet air ejector, with Inter- end.afulf condenser. A crib bouse at the rivwy edgo contains the traveling screen aq^n two vertical mixed-flow eirculttiou pumps. These discharge into two 24-lifl lines running s Uule over 250 ft to thj plant, and thenco under the boiler rboM to the condenser inlet connections. Q& of these lines, which expands toJ6,iqL forms the discharge to a scaling yreW at the west aide of the plant (see m lion). In normal operation, the iqtu line not connected to the dltchany handles full Intake (low, with disebaru to the sealing well through the'56;i& section of the other line. In winter, ujj normal discharge connection U rzlrv7 off and return flow is through the 24-uL line back to the crib house for wsnnioM Wont Performance.
