Which outcome arises when the heat exchanger of an organic Rankine cycle engine fouls?

A)Reduced turbine output from lower vapor pressure✓

B)Increased pump cavitation due to higher NPSP

C)Elevated generator temperatures from increased current

D)Enhanced cycle efficiency at lower temperatures

💡 Explanation

When heat exchanger fouling occurs, thermal resistance increases, reducing heat transfer to the working fluid, decreasing vapor pressure and thereby reducing turbine power output because pressure differential has decreased. Therefore, reduced turbine output results rather than the listed alternatives since flowrate isn't forced and temperature increase in the engine isn't affected.
