This progress report presents the preliminary results of the gasification of pulverized coal by steam-oxygen mixtures in a vortex reactor. The basic principles of reactor design, and an illustrative example of their application are given. A method of calculating the composition of the gas produced in this reactor is presented and has been checked experimentally. The carbon conversion and the limits of operation have been found to be closely related to the type and uniformity of the coal distribution. A method of improving the operation of the equipment and the quality of the gas by a change in the type of coal distributor appears to be promising.
