Abstract

In this study, the hybrid of organic Rankine cycle with heat recovery system of low temperature gases in Electric Arc furnace has been investigated. Moreover, the effect of the steam accumulator on stabilizing the mass and heat of exhaust gases of the heat recovery boiler is shown. Hence, constant thermal power has been achieved for a longer period of time for the organic Ranking cycle. The steam accumulator thermodynamic model is simulated based on the non - equilibrium thermal model for the liquid and vapor phases. Furthermore, the steam accumulator pressure variations with different mass outflow rates have been investigated. Constant and continuous thermal power has been reached with an output mass flow rate of 2.84 kg/s during four processes of the electric arc furnace. The transient state of the aforementioned hybrid system has been studied from the energy and exergy points of view. The energy and exergy efficiencies of the whole system are calculated with three working fluids Hexamethyldisiloxane, Toluene, and R245fa of the organic Ranking cycle. Toluene with thermal and exergy efficiencies of 16.4% and 27.1%, respectively, is suitable for use in the organic Ranking cycle compared with the other two fluids.
