Performance Assessment of an Integrated Coal-Air Turbine Power Generation System with Enhanced Steam Cycle

Öz

In Türkiye, most coal resources are lignite and generally have a low calorific value. It is essential to use this domestic resource to reduce Türkiye's external dependency. This study aims to analyze and compare the performance of an integrated power plant model using low-calorific-value coals from the Kütahya region, specifically Tunçbilek and Seyitömer coals, as primary energy inputs. In this study, a novel combined cycle configuration was modelled, where compressed air is heated through the HX1 (heat exchanger) inside the boiler and directed to an air turbine to produce electricity. The exhaust air from the turbine is utilized in a heat recovery steam generator (HRSG) to heat steam and feedwater, while the high-temperature flue gases from the boiler contribute to additional steam generation. The superheated steam is expanded in a condensing steam turbine to generate further electricity, with injection steam supplied from the turbine discharge. The results of this study indicate that the maximum net electrical efficiency was obtained as 35.83% for the Tunçbilek coal-fired power plant model and 32.57% for the Seyitömer coal-fired power plant model. The corresponding net heat rate values were determined as 10,670 kJ/kWh and 13,251 kJ/kWh, respectively. The novelty of this study lies in the comparative thermodynamic evaluation of two locally sourced Turkish lignites within an integrated air–steam power generation system. Unlike conventional single-cycle coal plants, this approach provides an innovative pathway to improve overall system efficiency and reduce specific fuel consumption for low-grade coals, contributing to sustainable energy generation strategies for Türkiye’s existing thermal infrastructure.
