Abstract

The concept of Thermoeconomicsis a simple way to investigate economic aspects of thermodynamic losses and their potential recovery. The contemporary work presents the thermoeconomic study of an industrial fire tube packaged boiler as a case study. Energy balance and exergy balance were performed to determinepotential irreversibilities in various boiler sections. The effect of combustion air temperature, energy recovery from steam generator, steam superheating andflue gas temperature was simulated to study the exergy destruction and efficiency enhancement of combustor, heat recovery section and stack,respectively.Thermodynamic analysis on boiler showed energy and exergy efficiencies of 74.16% and 31.76%, respectively.It was found that steam generator caused maximum exergy destruction (45.45%) followed by combustor (45.16%) and stack (9.1%),whereas; stack resulted82.77% of total thermal losses in the boiler.Results revealeda saving of 10.6% in fuel consumptionand 10.31 million-PKRs of annual operating cost by optimizing operating parameters of the boiler.
