Abstract
Melting furnace is largely classified into two types : one is electric type and the other is fuel type. The fuel type is better applied for the middle or small sized incinerator without generating equipment, which we have tested at this time. We have enriched with oxygen the combustion air for the fuel type surface melting furnace, aiming to attain the reduction of the fuel necessary for combustion and the reduction of exhaust gas generation. As the result, we have confirmed that we could attain 6% reduction of the fuel gas at the time when the the concentration of oxygen is 23.2%. We have obtained this figure both by experiment at the testing furnace and by theoretical calculation, and have found that those two figures are almost same.
