CFD ANALYSIS FOR ADAPTABILITY OF PRODUCER GAS FOR POWER GENERATION IN GAS TURBINES

Gas turbines are low specific fuel consumption prime movers for power generation. The situation of increasing demand for power generation with “Carbon Neutral” technologies is the need of hour. Earlier research studies indicated the feasibility of utilization of low calorific value gas in Gas turbines, but reported a large quantity of Exergy destruction in combustion chamber. The present paper addresses the adaptability of producer gas in a combustion chamber, with a non-premixed model using Ansys-Fluent. A 3D test combustion chamber of 15 cm diameter and 30 cm long with circular air inlets and axially located fuel inlet are modeled and simulations are performed using commercial CFD software. A 25 KW gas turbine combustion chamber is considered with operating pressure of 4 bar absolute working on Producer gas with the fuel composition of 19% H2, 20 % CO, 2 % CH4, 10% CO2 and remaining N2. Combustion chamber operating with the producer gas is presented. The obtained results are compared with methane and comparative analysis is presented.
