Gasification of carbon-bearing raw materials in plasma-arc electric furnace with heater and risk of explosion in syngas mixtures

摘要

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 H_2 and between fuel and oxidizer are shown for the first time.
