Performance Evaluation of Ge Ms6001b Gas Turbine Based on Exhaust Gas Composition and Turbine Inlet Temperature

Year: 2026

Abstract: One of the sustainable development goals (SDG) of the United Nation is on climate control which this paper intends to address in the area of exhaust gas emission from a gas turbine plant. The flue gas from the expander contains residual heat and carbon dioxide, which if not properly managed, contribute to energy losses and environmental degradation. This study is essential for improving overall plant efficiency, reducing irreversibilities and identify opportunities for waste heat recovery and carbon capture. The study focuses on performance evaluation of a gas turbine plant by examining key thermodynamic and environmental parameters, including turbine inlet temperature, combustion products, flue gas temperature, mass flowrate and carbon dioxide concentration. The study showed that exhaust composition is governed by air–fuel ratio and essentially independent of pressure ratio. Air–fuel ratio therefore controlled power, emissions and capture potentials. The exhaust gas can be minimised by using technic such as carbon capture. Turbine inlet temperature fell steeply with air–fuel ratio, at roughly 16 K per unit, from 2,245 K to 954 K. The design point for GE MS6001B gas turbine of AF = 61.5 placed the machine at about 1,200 K, the metallurgical limit of the uncooled MS6001B, extracting maximum power consistent with safe blade temperature. It is recommended that waste exhaust heat is recovered rather than rejected in the cooling train, as this is where there is great thermodynamic gain and carbon capture be integrated in the plant to reduce harmful emission.
