“…One of the modified configurations resulted in 2 % to 9.4 % higher net work output than the standard Kalina cycle power system with a throttle valve. In a similar kind of study, Sadeghi et al [167] proposed and optimized a double-turbine Kalina cycle power system with two separators using the artificial bee colony algorithm. Optimal values for the inlet temperature and pressure for one of the separators were reported for obtaining the highest thermal efficiency.…”

“…Nowadays, an optimal design of the structures plays a significant role in determining the best operating conditions, which may lead to a reduction in the final cost of the construction projects. Optimization algorithms have been broadly used during the last decade chiefly for energy system applications [22,23]. Multi-objective optimization is a method of multiple criteria decision-making that is mainly related to mathematical optimization problems including more than one objective function with equality and inequality constraints to be optimized, simultaneously [24].…”

In this paper, four types of plate-fin heat exchangers applied in 200 kW microturbines are investigated. Multi-objective optimization algorithm, NSGA-II (nondominated sorting genetic algorithm (GA)), is employed to maximize the efficiency of the recuperator and minimize its total cost, simultaneously. Feasible ranges of pressure drop, Reynolds number, and recuperator efficiency are obtained according to a penalty function. The optimizations are conducted for rectangular fin, triangular fin, louver fin, and offset strip fin recuperators with cross and counter flow arrangements. The results of each optimization problem are presented as a set of designs, called “Pareto-optimal solutions.” Afterward, for the designs, cycle efficiency and net present value (NPV) are compared based on technical and economic criteria, respectively. Maximum cycle efficiency occurring in a recuperator with louver fin and counter flow arrangement is found to be 38.17%. Finally, the optimum designs are compared based on nondominated sorting concept leading to the optimal solutions.

“…Guo et al 15 introduced a Kalina cycle, which is able to utilize the heat source's energy and is capable of reducing the exhaust temperature via a double-pressure evaporator. Sadeghi et al 16 considered a double turbine Kalina cycle, which is able to match heat sources' temperature in the range of 353.15-473.15 K properly. Their results revealed that the innovated cycle requires less amount of energy when the separator pressure increases.…”

In this study, an arrangement of Kalina cycle is proposed in which it is intended to implement weak solution of Kalina cycle system 11 (KCS 11) for more power production. In this cycle, which is a version of KCS11 (KCS111), the weak solution of the traditional separator is heated in hot section of the evaporator. The stream that now includes vapor is separated in high-temperature separator that brings about an extra potential to produce work. In order to set pinch temperature in each of the heat exchangers included in the cycles an iterative method is used. The two cycles are compared for the same conditions as the base case, which is followed by a comprehensive sensitivity analysis. The consequences of streams' curves in the heat exchangers are considered to present analytical justification for the improvements. Comparing the cycles at the base condition, it is observed that the presented cycle improves the exergy efficiency by nearly 18% while more than 17% improvement at the optimum ammonia mass fraction is achievable. Results show that, the proposed cycle produces larger mass flow rate of vapor passing through the turbines and is more efficient than KCS 11 for varying ammonia mass fractions. Results indicate that the trend of thermal efficiency versus ammonia mass fraction is descending for the both cycles.
