We have .ht motor which is 60Hz.we run on 50Hz.so that it's speed reduce
but we had one prob.that motor winding temp increase up to 135 deg.we
want reduce this temp.what to do?we arrange ext.cooling fan but not much
effect.we want reduce this temp. Inhouse without affecting much.cost. also
don't want reWINDING OF MOTOR?

As you have reduced the speed ,the cooling effect of the
shaft mounted cooling fan is also reduced .Either you have
to reduce the load by about 10% or replace cooling fan .

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
