The invention relates to the field of gasification of a carbonaceous feedstock and can be used in the chemical, petrochemical, coke-gas and energy industries. A method for gasification of a carbonaceous feedstock comprises partial oxidation of the carbonaceous feedstock in an oxidation chamber in a mixture of oxygen-containing gas and water vapour in a partial oxidation channel, which is mounted coaxially in the vertical oxidation chamber. The water vapour for the partial oxidation of the carbonaceous feedstock is supplied at the input and output of the vertical oxidation chamber of a combustion chamber. A gas producer comprises a housing, a burner device, a vertical oxidation chamber, manifolds for supplying carbonaceous feedstock, water vapour and oxygen-containing gas, a pipe for discharging gasification products, a slag removal chamber, and also a partial oxidation channel, which is arranged coaxially in the vertical oxidation chamber and is attached to an upper internal part of the housing, in which the burner device is installed. What is achieved is the production of producer gas with an elevated concentration of hydrogen.
A method of gasification of carbonaceous feedstock, including partial oxidation of carbonaceous feedstock in an oxidation chamber in a mixture of oxygen-containing gas and water vapour characterized in that partial oxidation is carried out in a partial oxidation channel which is mounted coaxially in a vertical oxidation chamber, and water vapour supply for partial oxidation of carbonaceous feedstock is carried out at the input and output of the partial oxidation channel of the oxidation chamber.
A gas producer comprising a housing, a burner device, a vertical oxidation chamber, manifolds for supplying carbonaceous feedstock, water vapour and oxygen-containing gas, a pipe for discharging gasification products, a slag removal chamber, is peculiar for the fact that the partial oxidation channel is additionally introduced into it. The channel is arranged coaxially in the vertical oxidation chamber and is attached to the upper internal part of the housing in which the burner device is installed.
