Interactive Effect of Plasma Power and Equivalence Ratio upon Plasma Gasification of Coconut Shell

摘要

Plasma gasification is a promising technology which aids in energy recovery and disposal of organic wastes. A gasification study on effect of plasma power and equivalence ratio on gas composition had been carried out using non transferred DC type plasma torch with air as carrier gas. The experimental trials on plasma gasification were done with varied plasma power (4.8,8.1, 12.4,17 and 21.6 kW) and equivalence ratio (0.1 to 0.4). The composition of the produced gas was analyzed and the result obtained from the trials showed that the maximum heating value of the produced gas was 5.75 MJ m3 at higher plasma power 21.6 kW and lower equivalence ratio 0.1.
