A mathematical model of the solid fuel conversion process which is used to analyze the synthesis-gas that is the result of coke gasification is proposed. During the conversation of coke in an environment of high-Temperature water vapor, synthesis-gas consisting of hydrogen, oxide and carbon dioxide is obtained. That is shown in the article. Hydrogen in the produced gas at any oxidizer temperatures is always over 50% of total volume. The ratio of oxide and carbon dioxide depends on the temperature of the oxidant. The lower the oxidant temperature, the greater the proportion of carbon monoxide. It is established that it is economically more advantageous to use water vapor with the addition of oxygen as an oxidizer in the gasification of fuel. With the use of such an oxidizer, synthesis-gas consisting of 100% of the combustion gas is obtained. The temperature of the steam-oxygen oxidant after the fuel has ignited can be significantly reduced practically before the beginning of the process of vapor condensation. The synthesis-gas produced in this gasification process will contain in volume proportions about 25% hydrogen and 75% carbon monoxide.
