The problem table cascade for a process is given in Table 23.11 below for Tmin = 30 C. This process is to be integrated with a steam turbine in a cogeneration scheme. The inlet steam is at 41 barg and 400 C. a. The rate of power generation can be determined from the Willans' Line Model with parameters from Table 23.1 and intercept ratio of 0.05, assuming a mechanical efficiency of 95%. Calculate the power generation for a fully loaded turbine if the inlet steam flow to the turbine is fixed to satisfy process heating requirements. b. Calculate the heat duty of the fuel consumed in the generation of steam if the theoretical flame temperature in the boiler is 1800 C and the ambient temperature is 15 C.

The fuel consumption can be reduced by air preheat to the boiler by recovery of waste heat from the process. Calculate the fuel consumption and power generation if air preheat is maximized. Assume that the heat capacity flowrates of combustion air and flue gas are equal. Acid dew point for the flue gas is 150 C
