Re-powering Study for the Northport and Port Jefferson Power Stations Appendix II Northport System Descriptions Industrial grade aqueous ammonia at 19% concentration is received by truck. A vapor return line from the ammonia storage tank back to the delivery truck provides venting of the tank during filling operations. A single storage tank provides five days of capacity based on full load operation of the particular option. From the tank, two 100% ammonia feed pumps convey the aqueous ammonia through a strainer to the ammonia vaporization skid for each HRSG. A self regulating positive displacement pump maintains the required flow and a constant pressure to a dedicated injection skid for each HRSG. The injection skid mixes the ammonia with high temperature flue gas drawn off the HRSG to vaporize the ammonia as necessary to obtain proper distribution into the exhaust gas via the ammonia injection grid located inside the HRSG upstream of the SCR. The injection skid includes two 100% blowers. 2.11 Component Cooling Water Refer to P& ID 09-09A thru 09D in Appendix III. The CCW System supplies cooling water to the steam turbine lube oil coolers, steam turbine generator hydrogen coolers, the combustion turbine(s) lube oil coolers, combustion turbine(s) generator hydrogen coolers, the sampling system sample coolers, and any other plant components that require cooling water. Two 100% capacity pumps provide the motive force for circulation of the closed cooling water to the system users. The pumps are horizontal, single stage, centrifugal pumps. Butterfly valves are installed on the intake and discharge of each pump. For pump protection, a check valve is installed on the discharge side of each pump. A fin-fan type heat exchanger is used to transfer CCW heat duty to the atmosphere. A surge tank is provided to allow for thermal expansion, and acts as a surge volume for the CCW System water. The surge tank, which is installed at the highest point in the system, also provides net positive suction head (NPSH) for the CCW pumps. The surge tank is equipped with level instrumentation, which provides signals to operate an automatic make-up valve. Make-up water is supplied from the Condensate System. A chemical addition pot is installed for the addition of chemicals to control corrosion within the CCW System. The CCW System supplies the following components with cooling water: • Steam Turbine Lube Oil Coolers • Steam Turbine Generator Hydrogen Coolers • Steam Turbine Generator Exciter Coolers • Steam Turbine Generator Seal Oil Coolers • Combustion Turbine Lube Oil Coolers • Combustion Turbine Control Oil Coolers • Combustion Turbine Starting Package Oil Coolers • Combustion Turbine Generator Hydrogen Coolers • Combustion Turbine Generator Seal Oil Coolers March 30, 2009 164
Re-powering Study for the Northport and Port Jefferson Power Stations Appendix II Northport System Descriptions • Condenser Vacuum Pumps [if applicable] (Cooling is provided to the liquid ring vacuum pump heat exchangers) • Feedwater Pump Lube Oil Cooler [if applicable] • Sample System Sample Coolers • Instrument/Service Air Compressors [if applicable] System components that could be subject to greater than their design pressures during operation are protected from over pressure during operation by pressure relief valves. Temperature control valves regulate cooling water flow through the turbine lube oil coolers and generator coolers. The flow of closed cooling water through the various components is either automatically regulated, or manually adjustable to meet each manufacturer’s recommendations. 2.12 Instrument & Service Air Refer to PID 12-01A and 12-02A in Appendix III. At Northport, compressed air is supplied throughout the facility and subdivided into instrument air and service air according to the air quality requirements. The instrument air serves all users where dry oil-free air is required (i.e. air operated control valves, instrumentation), where there is a potential of freezing the service air line or if interruption of the air supply is not acceptable (i.e. atomizing air to the ammonia skid for the SCR system). The service air serves common users in the plant such as tools via hose connection stations located throughout the facility. The Instrument/Service Air System will have the following characteristics: Two (2) x 100% air compressors of the air-cooled (or water-cooled), lubricated, and rotary screw type. Each compressor is equipped with an inlet air filter silencer, air/oil separator vessel, air/water separator, aftercoolers, and controls. One (1) x 100% service air receiver is provided. The receiver provides surge capacity for the Service Air and Instrument Air Systems. It is constructed to ASME Code requirements and is designed for safe shutdown of the facility. The piping and control system will be arranged to prevent loss of pressure to the instrument air system on a service air system failure by a pressure control valve. The pressure control valve isolate the service air header on low instrument air pressure signal from the instrument air header and diverts air to the instrument air system. One, 100% duplex air drying train for the instrument air system. The train consists of a prefilter, air dryers, and after filter stations. The prefilter removes the bulk liquid water and particles (5 microns or smaller). After the air passes through the dryer, the after filter removes any particles from the dryer desiccant (3 microns or smaller). The air dryer is of the dual tower heatless regenerative desiccant type. The system automatically controls the regeneration cycle of the dryers as required. Each air dryer tower is 100% unit capacity such that one tower can supply full unit demand while the other is being regenerated. Each dryer and dryer tower will be equipped with remote operated isolation valves. March 30, 2009 165
