Abstract

Saw dust was gasified at combined and separated impact of the heater and arc discharge on the raw material. It is shown that because of combustion of a part of produced syngas in the heater the raw material can be gasified with power inputs reduced by 20-25 % in comparison with plasma gasification. Data on parameters of combustion and detonation of syngas mixtures with oxygen and air at a change in the ratio between fuel components CO and H2 and between fuel and oxidizer are shown for the first time.
