Power enhancement of a turbo-charged industrial diesel engine by using of a waste heat recovery system based on inverted Brayton and organic Rankine cycles

In this study, energy assessment is performed for an industrial turbocharged diesel engine integrated with a novel waste heat recovery (WHR) system. The exhaust used in inverted Brayton cycle (IBC) purpose. Also, the from IBC exchanger as source organic Rankine (ORC) to produce extra power. case study modelled AVL BOOST software and model validated against real performance data. For studying of proposed system, added thermodynamic ORC developed MATLAB it linked BOOST. Then, solved, main output parameters are studied at 1800 RPM various loads. results show that employment WHR system leads enhancement power by about 18%. However, backpressure produced installing can result increase BSFC up 3% reduction total thermal efficiency almost 1% full load condition. work contribute determine interactions between (IBC-ORC) engine. bottoming based on IBC-ORC be installed existing stationary engines generation without imposing new generation.
