In a cogeneration scheme, a Diesel engine-generator is used. The Diesel engine-generator is rated at 2000 kWe. The thermal efficiency is 0.38 based on the lower heating value of the fuel (44,000 kJ/kg). The air/fuel ratio by mass is 20 to 1. The exhaust temperature is 430 C and specific heat of the exhaust gas is 1.1 kJ/kg K. The exhaust gas is used to generate steam in a heat recovery boiler. The gas leaves the boiler at 255C, and dry saturated seam is produced at a pressure of 1.5 MPa.

(A)What is the heat to power ratio for the diesel engine generator?

(B)What is the total efficiency of the cogeneration scheme?
