Answer Posted / gunasekaran
suppose we are using 220KW motor and 0.7 pf we can calculate
the capacitor bank capacity through following formula
p=220KW
s=220/0.7 =314KVA
q=sqrroot(ssqr-psqr)
q=224 KVAR for unity p.f

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
