The distillate fuel oil system shall consist of two pumps (One standby, oneoperative) of suitable capacity for the maximum output of the turbine at lowestambient temperature at the site, along with necessary valves, piping, regulatingdevices, metering device, instrumentation, pressure switches and indicators.Scope of supplyOne distillate fuel supply system shall include, at least, the following equipment:-One off-base standardized forwarding skid consisting of the pumping andregulating equipment- One off-base standardized filtering (duplex cartridge type filters) located nearthe unit-Piping between forwarding and filtering skid and from the filtering skid up to thegas turbine unit-Unloading Fuel skid-2(Two) 50.00 lac litre distillate fuel storage tank with fixed roof having floatingsuction type delivery-Piping from unloading area to fuel tank.-For unloading: Two 100% (100m 3 /h) transfer pumps + Filters-Piping between the 50.00 lac fuel storage tank and pumping skid- Rehabilitation of existing fuel unloading facilities including jetty.-Fuel strainers-Flow-meter and totalise to measure fuel consumption-Pressure gauges on each side of fuel strainers, at pump suctions and discharge,and other critical points- Fuel oil pumps-Over speed and emergency trip stop valves-Control valves for starting and operating-Necessary isolation valves-All piping-Automatic control valvesScope of workThe contractor shall design, manufacture, inspect, test, deliver to the site andinstall of liquid fuel oil handling, conditioning and regulating facilities with allaccessories as specified hereunder for the plant.The unit shall be furnished with a complete liquid fuel oil system. The liquid fueloil handling system shall also be provided.1. Fuel forwarding skidFuel forwarding skid brings liquid fuel to the gas turbine at a pressure consistentwith the gas turbine fuel supply requirements.Equipment list:-Two (2) 100% fuel forwarding AC motor driven centrifugal pumps (one duty, onestandby), each for the maximum fuel flow necessary to the gas turbine-Three suction StrainersGhorasal 200 MW to 300 MW Gas Turbine Peaking Power Plant Project (Vol-2 of 3)26
-One fuel pressure regulating valve-One relief valve-Complete set of piping including valves, gauges and fittings of all linesterminating at the skid boundary2. Fuel oil filters SkidThis unit provides liquid fuel filtration up-stream the unit turbine and includes thefollowings:-Two fuel filters (one duty, one standby) : Filter cartridge -5 microns-One pressure metering panel board including : one manostat (fuel pressurecontrol), one different pressure gauge-One fuel accumulator-One stop valve-Complete set of piping including valves, gauges and fittings of all linesterminating at the skid boundary3. Fuel storage tankThe fuel storage tank is a vertical with fixed roof tank. Its capacity of each tankshall be minimum 50.00 lac litre. The fuel storage tank will be assembled in siteand includes the followings:-One fuel inlet flange-One fuel outlet flange with floating suction-Two manholes located in shell and in roof-Two foam chambers for fire protections-One visual level gauge-Various levels switch to provide alarm at subsequent level-one gas vent-One water drain-One spiral stairway and one top peripheral hand railing4. Unloading Fuel skidRequired piping, along with, other facilities that will be required for the systemfrom unloading base to the fuel tank to be constructed for the proposed plantshall be made by the contractor.The unloading fuel skid includes the followings-2x100% fuel screw pumps (one running, one standby), capacity of each 100m 3 /h and driven by AC motor.-Two suction strainers-Two headers, each with five unloading points-One flow meter-Piping and valves between above equipment5.
