چکیده انگلیسی
This work includes the analysis of operating characteristics of water vapour plasma system which were investigated in the following range of plasma source parameters: power of plasma torch was 25-45 kW; arc current was 140-180 A, the arc voltage was 172-231 V, the efficiency was 0.5-0.78, the average temperature of water vapour plasma jet in exhaust nozzle was 2600-3500 K, and the plasma jet velocity was 200-310 m sâ1. Holding the temperature above 2300 K and water vapour flow rate at 132 l minâ1, it is possible to reach the sufficient conditions for the biomass conversion to syngas. Spectral analysis of plasma jet outflowing from plasma torch exhaust nozzle showed that water vapour plasma contains an increased amount of hydrogen that is usable in many plasma chemical processes. The summarized results can help to calculate and design gasification systems of biomass, to establish optimal parameters for stable operation of plasma generator and regulate the process parameters.
