Diesel engines in continuous operations/cogeneration plants: Better in the long run
Continuous operations means that engines run over 8,000 hours/year – that is, almost year-round. This is a task that MAN diesel engines live up to reliably because they are specially designed to meet the economic requirements of gensets and cogeneration plants. Particularly the latter must be built to handle basic energy needs economically.
COP = Continuous Power

(1) ISO standard fuel stop power (without auxiliary drives); ISO standard power (without auxiliary drives) 10% overloadable. The nominal ratings are valid for an air temperature of 25° C, an air pressure of 100 kPA (1000 mbar) = 1000 m height over sea level and a relative humidity of 30%. Power reductions owing to other line-up conditions have to be taken into consideration. Performance definition as per ISO 3046/1. Usage definition LTP, PRP, COP as per ISO 8528-1
(2) Electrical output kWe 10% overloadable at common power-dependent generator efficiency level between 0.93 - 0.96. Power reduction taken into consideration for ventilator fan.
(3) Generator power in kVA at power factor cos. phi. 0.8, rounded off according to generator class. 10% overloadable, power reduction taken into consideration for ventilator fan.
