D.G if ac is rated in KVA.Usually the alternator is rated at 0.8 pf. So KW/PF=KVA. 110/0.8=137.9.KVA.
Now the D.G must have some spare power to take care of starting current and a bit of future expansion so we load the D.G at 75%.
137.9/.75=183.8KVA
Now you can buy the nearest available D.G in the market.
Maybe 175KVA or 185 KVA

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
