Abstract

Ošmera, Tomáš. Application of Validation Model for Verification of Operational Data of HRSG Boiler PPE Počerady and Proposal of Measures for Increasing Efficiency of HRSG Boiler in its Cogeneration Concept Master Thesis. Ostrava: VSB - Technical University of Ostrava, Faculty of Mechanical Engineering, Department of Power Engineering, 2025, 106 p. Thesis head: Konvička, Jaroslav.

This thesis focuses on a review of combined cycle systems and their effective integration into low-carbon energy sources. It also explores data processing, the development of validation models, and their implementation. The thesis discusses aspects of data quality, validation conditions, and the advantages and risks associated with data validation. The principle of validation tasks is analyzed through a case study of a combined cycle power plant equipped with a Heat Recovery Steam Generator (HRSG). Various approaches to improving cycle efficiency are proposed, including the recovery of waste heat from flue gases and the optimization of stack losses. The study also includes the design and thermal calculation of a finned tube heat exchanger for effective flue gas heat utilization.
