A gas producer for producing producer gas from a fuel such as coal effectively combines the unknown updraught and downdraught processes. The producer has an upper section (8) where an upper fire bed (16) is located and a lower section (9) where a lower bed (14) is located. A gas outlet (4) is positioned between the upper and lower beds. To ensure satisfactory feed conditions through the upper section, the walls of this section diverge downwardly. The angle at which they diverge should be less than the angle of repose of the fuel used. |
