1 1. INSTALLATION FACTORS Once the size of the generating set and the required associated control panel and switchgear have been established, plans for installation can be prepared. Proper attention to mechanical and electrical engineering details will assure a satisfactory power system installation. Factors to be considered in the installation of ...

2 4. GENERATING SET MOUNTING The generating set will be shipped assembled on a rigid base that precisely aligns the alternator and engine and needs merely to be set in place (on vibration isolation pads for larger sets) and levelled. See figure 4.1 4.1 Vibration Isolation It is recommended that the generating set be mounted on vibration isolation p ...

3 5. VENTILATION Any internal combustion engine requires a liberal supply of cool, clean air for combustion. If the air entering the engine intake is too warm or too thin, the engine may not produce its rated power. Operation of the engine and alternator radiates heat into the room and raises the temperature of the room air. Therefore, ventilation ...

4 5.2 Ventilators To bring in fresh air, there should be an inlet ventilator opening to the outside or at least an opening to another part of the building through which the required amount of air can enter. In smaller rooms, ducting may be used to bring air to the room or directly to the engine's air intake. In addition, an exit ventilator ope ...

5 5.3 Inlet Ventilator Size Before calculating the inlet ventilator size, it is necessary to take into account the radiator cooling air flow requirements and the fan static pressure available when the generating set is operating at its rated load. In standard room installations, the radiated heat is already taken into account in the radiator air fl ...

6 6. ENGINE EXHAUST Engine exhaust must be directed to the outside through a properly designed exhaust system that does not create excessive back pressure on the engine. A suitable exhaust silencer should be connected into the exhaust piping. Exhaust system components located within the engine room should be insulated to reduce heat radiation. The ...

7 6.2 Exhaust Pipe Flexible Section A flexible connection between the manifold and the exhaust piping system should be used to prevent transmitting engine vibration to the piping and the building, and to isolate the engine and piping from forces due to thermal expansion, motion or weight of piping. A well designed flex section will permit operation ...

8 Excessive restriction in the exhaust system can be avoided by proper design and construction. To make sure you will avoid problems related to excessive restriction, ask The FG Wilson distributor to review your design. The effect of pipe diameter, length and the restriction of any bends in the system can be calculated to make sure your exhaust sys ...

9 7. EXHAUST SILENCING Excessive noise is objectionable in most locations. Since a large part of the generating set noise is produced in the engine's pulsating exhaust, this noise can be reduced to an acceptable level by using an exhaust silencer. The required degree of silencing depends on the location and may be regulated by law. For example ...

10 8. SOUND ATTENUATION If noise level must be limited, it should be specified in terms of a sound pressure level at a given distance from the generator enclosure. Then the enclosure must be designed to attenuate the noise generated inside the enclosure to produce the required level outside. Don't attempt to make this noise level unnecessarily ...

14 10.2 Remote Fuel Systems Three types of remote fuel systems are recommended by the manufacturer: Fuel System 1: Installations where the bulk fuel tank is lower than the day tank. Fuel System 2: Installations where the bulk fuel tank is higher than the day tank. Fuel System 4: Installations where fuel must be pumped from a free standing bulk fuel ...

15 With this system, the basetank must include an overflow via the return line, sealed fuel level gauges and no manual fill facility. All other connections on top of the tank must be sealed to prevent leakage. Fuel System 2 is not compatible with the polyethylene fuel tanks standard on smaller generator sets. The optional metal tank is required. A ...

16 Flexible piping should be used to connect to the engine to avoid damage or leaks caused by engine vibration. The fuel delivery line should pick up fuel from a point no lower than 50 mm (2”) from the bottom of tank at the high end, away from the drain plug. 10.5 Day Tank Capacity The capacity of the day tank is based on the fuel consumption and ...

17 11. SELECTING FUELS FOR STANDBY DEPENDABILITY The types of fuels available for diesel engines, vary from highly volatile jet fuels and kerosene to the heavier fuel oils. Most diesel engines are capable of burning a wide range of fuels within these extremes. The following information will assist you in selecting the type of fuel that will afford ...

18 Other solutions are to add inhibitors to the fuel or to obtain greater turnover by using the fuel for other purposes. A gum inhibitor added to diesel fuel will keep it in good condition up to two years. If the building furnace has an oil burner, it is possible to burn diesel fuel in the furnace, connecting both the engine and the furnace to the ...
