Performance analysis of combined cycle power plant inlet air cooling by a novel optimized vapour absorption refrigeration framework
Abstract
A Combined Cycle Power Plant (CCPP) is utilized for generating electricity, and it is a highly effective, efficient generation unit of power. However, heat absorbance maximization has played a significant role in CCPP applications. The heat absorbance system has recorded less heat absorbance rate in many cases. Hence, the present research is focused on CCPP with Heat Recovery Steam Generator (HRSG) and Vapour Absorption-based Refrigeration (VAR) cooling system based on Lithium Bromide-Water (LiBr/H2O). Furthermore, the thermodynamic model for the air cooler and the integrated system was analyzed. Moreover, a novel Hybrid Ant Colony Bat Absorber system (HACBAS) was developed to optimize heat absorbance and energy. This process has maximized the Coefficient of Performance (COP) of the absorbance to the desired level. The CCPP absorption system simulation model is carried out with the MATLAB platform. In addition, the presented model has gained the optimized COP as 0.97%, and the gained energy efficiency is 95%. Also, the recorded generation by the designed model is 943MW. Hence, the presented optimal solution is suitable for the CCPP applications to optimize the heat absorbance rate and maximize energy efficiency.
