Abstract
The exergy analysis of rice husk fired steam power plant has been performed by using simulations in aspen hysy. Small portion of steam produced is used for paddy drying while major portion is used for operation of steam turbine for in-house electricity production Thermodynamic parameters are extracted from aspen hysys for calculations. Case studies are included to check the effect of different parameters on efficiency of equipment. Exergy analysis is carried out on running conditions of the plant and overall plant exergy efficiency calculated is 57.10%. Maximum exergy destruction was found in case of boiler, which is due to incomplete combustion processes & inappropriate insulation. Other parameters were determined that caused decrease in exergetic efficiency of the plant and remedial actions are suggested. Case studies are included to check the effect of different parameters on efficiency of equipment.
