Abstract

PURPOSE: To enhance carbide yield by covering the surface of a raw material layer consisting of a carbon material and lime with a combustible gas based on CO and/or H2 to prevent consumption of the carbon material due to CO and H2 gases formed by the reaction of the material and combustion gas when the layer is directly heated with heat of combustion of fuel to be allowed to react.
CONSTITUTION: A carbon material such as coke and lime such as quick lime are continuously and unfiformly scattered in a reactor, and hydrocarbon type fuel such as heavy oil and air are supplied from the upper part of the reactor to burn the fuel, whereby the material and lime are allowed to react by direct heating to produce CaC2. At this time, a combustible gas based on CO and/or H2 is introduced into the lower part of the reactor or onto the surface of the raw material layer to cover the raw material and reaction surfaces with the gas current. Thus, decomposition of the formed CaC2 by the reaction with CO2, H2O and O2 in combustion gas is prevented. The ratio of the combustible gas introduced is needed to be limited to 5W50% (as energy) to the fuel.
