This Concept Map, created with IHMC CmapTools, has information related to: One boiler in operation and Auxiliary Plant Operation 3, When the main condenser vacuum approaches the auxiliary condenser vacuum, open either the main or auxiliary condensate suction valve, depending on which pump is selected as the in use unit. Stop the standby pump. By then All exhaust dumps to the main condenser and both main condensate and atmospheric drains condensate system in use. The main turbine has its vacuum raised with gland steam in use. The main turbine and stern tube LO systems are in use. The main turbine is being turned with the turning gear., All exhaust dumps to the main condenser and both main condensate and atmospheric drains condensate system in use. The main turbine has its vacuum raised with gland steam in use. The main turbine and stern tube LO systems are in use. The main turbine is being turned with the turning gear. Ensure All the exhaust and drain systems are transferred from the auxiliary to the main condenser. Isolate and shut down the auxiliary condenser and associated condensate system., Crack open the main turbine gland steam make-up bypass valve and allow the turbine to warm through slowly. then Open the central fresh water cooling system to the main turbine LO cooler., Start the gland condenser exhaust fan. Open The suction / discharge / casing vent to one of the main condensate pumps. Fill the main condenser to a working level from a distilled tank. Start the main condensate pump., Place all pumps in use to remote start and their second pumps to standby conditions. Next When the auxiliary condenser has cooled down, shut down the SW cooling system and stop the auxiliary circulating pump., Open the valves for the sea water cooling supply to one vacuum pump cooler. Open the air inlet valve to vacuum pump diffuser from the main condenser. Start the vacuum pump and start raising the main condenser vacuum. after that When the main condenser vacuum approaches the auxiliary condenser vacuum, open either the main or auxiliary condensate suction valve, depending on which pump is selected as the in use unit. Stop the standby pump., The suction / discharge / casing vent to one of the main condensate pumps. Fill the main condenser to a working level from a distilled tank. Start the main condensate pump. then proceed to Open the valves for the sea water cooling supply to one vacuum pump cooler. Open the air inlet valve to vacuum pump diffuser from the main condenser. Start the vacuum pump and start raising the main condenser vacuum., Opening the gland steam make-up and spill inlet and outlet valves. Adjust the controller set steam pressure. Next Start the gland condenser exhaust fan., All the exhaust and drain systems are transferred from the auxiliary to the main condenser. Isolate and shut down the auxiliary condenser and associated condensate system. With all required valves open Place all pumps in use to remote start and their second pumps to standby conditions., Open the central fresh water cooling system to the main turbine LO cooler. followed by Opening the gland steam make-up and spill inlet and outlet valves. Adjust the controller set steam pressure., The plant is operating on with both boiler Finally Main Plant Ready For Operation
