Plazma gazlaştırma sistemlerinin tasarım ve performansı üzerine deneysel araştırma

Syngas is produced through gasification of solid fuels. It includes carbonmonoxide (CO), carbondioxide (CO2), hydrogen (H2), methane (CH4) and low amount of hydrocarbon depending on the system operation conditions. In this study, gasification of solid fuels at various flow rate and plasma power by microwave plasma gasification is investigated. All the parameters; temperature, mass and content of syngas, fuel and ash, are measured and the comprehensive thermodynamic analysis of the process are carried out. The MCw gasifier consists of plasma generation system, gasification reactor, fuel-fluid supply system, process output (ash) collection system and measurement/data acquisition chain. The gasification of solid fuels; Russian, South African and Şırnak (Turkey) coals, pine tree and hornbeam sawdust and polyethylene is processed by MCw gasifier. The plasma gasification medium is formed of air and the air flow rate varies between 50 and 100 sL/min, the plasma power varies between 3 kW and 6 kW. According to the experimental results, the syngas temperature alters between 621 ℃ and 1276 ℃. The syngas production varies between 0.66 kg and 1.2 kg. The process energy efficiency ranges from 30.8 % to 86.04 %. The system energy efficiency changes from 20.6 % to 61.37 %.
