October STATION G Broddock Light and Power Co plant first -two units of new. station at Alexandria, Va. on banks of the Potomac.' Plant ultimately will have total 'of five units not Interconnected and will use fresh water from ihe Po tomac River for cooling. Inatcad of having stearn'jet air ejectors the con denser olr evacuation will be performed by two motor-driven rotary air-removal pumps for each unit Each pump has a capacity of 540 cfm at 1 in. Hg aba pressure. Because of the appreciable gradient from the river bank to the pleat and also because of subsoil limitations maincondenser circulating water must be led through steel pipes- Inlet pipes lead ing to the oondensers will be 54 in. die; discharge lines will be 48 in. dia connecting to a 96-In. pipe run ning through e tunnel to a teal pit southwest of the plant building. Both the circulating ohd drainage water will discharge to the river' from the aeA) pit through 84-in. concrete pipes. One complete 8tin. lino and 330 ft of second line will be installed initially. In the power plant building the cir* culaUng-water piping will be run above ground and largely overhead since sub soil conditions will not allow an under ground tunnel without requiring con current expensive foundation construc tion. Two circulating pumps of the verti cal type with 33,450-gpra capacity sgeinst 49-ft total head serve each main condenser. Each pomp is driven by a S00-hp 590-rpm 2300-v motor. Tbs pumps will be housed on the river bank. .Adjacent to the pomp house will be A building for chemical feed and atorage, chlorinating control equipment and chlorine storage. This building will alto serve en outdoor cold-process clari fier for evaporated makeup water and bearing cooling water. Circulating wa ter will be chlorinated under automaticcontrol at the pump suction. Steam Generators. The two 800,000lb-per-hr boilers produce steam at 875 psig and 925 F at the superheater out let Each unit has a superheater, wa* lerwaik, 2 tubular air heaters In paral lel end an economizer. Superheat con trol will be eflected by e combination of bypass damper setting end tilting burn ers.
