Duty Cycle:-
In telecommunications and electronics, the duty
cycle is the fraction of time that a system is in
an "active" state. In particular, it is used in the
following contexts:
Duty cycle is the proportion of time during which a
component, device, or system is operated.[1] Suppose a disk
drive operates for 1 second, and is shut off for 99
seconds, then is run for 1 second again, and so on. The
drive runs for one out of 100 seconds, or 1/100 of the
time, and its duty cycle is therefore 1/100, or 1 percent.

We are preparing another project which involves Waste heat recovery from a 1 MW GE Engine. The Engine in particular gives out flue gas at 487Deg C with a flow rate of 5650 kg/hour and this can be cooled to 180 Deg C. This gives a thermal output of ~ 594 KW that is available for input to VAM via heat exchanger / boiler. Additionally 581 KW will be available from engine jacket water (temperature profile 80/ 80 Deg C and a flow rate of 50m3/hr) Our estimation is that 300 TR of cooling is possible with a suitable VAM machine(s). Please advise what is the most suitable arrangement with maximum TR and min Capital expenditure. plz reply me as early as possible
