Prime Power rating is available for unlimited hours per year with a variable load of which the average engine load factor is 80% of the published prime power rating, incorporation of a 10% overload for 1 hour in every 12 hours of operation which is permitted. Standby Power rating is for the supply of emergency power at variable load for the duration of the non-availability of the mains power supply. NO OVERLOAD capacity is available at this rating. Engines must not be allowed to have facilities for parallel operation with the mains supply. This rating should be applied only when reliable mains power is available. Should this not be the case then refer to Prime Power rating. A standby rated engine should be sized for an average load factor of 80% based on published standby rating for 500 operating hours per year. Standby ratings should never be applied except in true emergency power failure conditions.DesignationUnits 50Hz 1500 rev/min60Hz 1800 rev/minContinuous BaseloadPrime Power Standby Maximum Continuous BaseloadPrime Power Standby MaximumGross engine power kWb 103712961422---Fan power kWm 42---Net engine power kWm 99512541380---BMEP gross bar 18,122,624,8---Combustion air flowm 3/min 83,6106110---Exhaust gas temperature max (after turbo)°C 442472483---Exhaust gas flow max (after turbo)m 3/min 285---Boost pressure ratio -2,83,533,84---Mechanical efficiency %889292---Overall thermal efficiency%424241---Friction power and pumping losses kWm 120---Mean piston speed m/s 9,5---Engine coolant flowl/s 17---Typical Genset Electrical Output 0,8 pf 25 °C (100 kPa)kVA 119415051656---kWe 95512041325---Assumed alternator efficiency%96---Energy balanceNote:Not to be used for CHP design purposes.
