Research Paper (postgraduate) from the year 2023 in the subject Engineering - Power Engineering, , language: English, abstract: In this work, regenerative and concentrated solar power (CSP) plants are examined for potential improvement in their operating efficiencies. The influence of the working fluid flow-rate and the vaporizer temperature on power generation was evaluated. Also, a novel waste recovery engine array model is described. In order to improve the thermal efficiency, consideration must be given to the range of values of the operating parameters, so as to attain the maximum efficiency value at the lowest possible cost. Power production in a developing nation like Nigeria has been witnessing incessant interruption. In this work, a power plant array with scalable potential is considered, suited to low-density population centers. One of the proposed application areas is the campus of University of Nigeria, Nsukka. Besides, regenerative and concentrated solar power (CSP) plants are examined for potential improvement in their operating efficiencies.
