I have seen that you have a PhD in Engineering and Energy so your might be able to help me with the problem. My problem is the following one: I have to size a CHP plant based on the techno economical data provided. They also give me a few tables with the demand pero hour, month... and requirements. 1) I have a CHP packaged unit (it costs 900$/KWe) with prime mover comprising 75% of total. 2)CHP plant 40% electricity efficiency and 40% waste heat recovery, the remainder being lost at MCR. 3) EL= 15 years 4) Discount rate 5% 5) inflation rate 2% 6) LP steam supplied at 130 C and 2 bar while condensate return temperature is 70C. 7) Existing diesel boiler efficiency 85%. 8) Diesel Engine availability 98%. Typical engine and part load performance is given in a table whit Heat Rate C.F. and Waste Heat Recovery C.F. I have to present and analyze my data. I have to do an Optimization Allocation of costs to heat and electricity... etc. I hope you could help me, Thanks a million, J.
