Water gas production device

The utility model relates to a water gas production device which comprises a reaction furnace, a feeding bin, a slag bin and an electric heating device, and the feeding bin and the slag bin are both provided with double-control gate valves; the upper part of the reaction furnace is connected and communicated with a water gas output pipe; a water vapor input port is formed in the furnace wall of the reaction furnace and is connected with a water vapor input pipe; the furnace wall of the reaction furnace is a steel body, and an electric heating device is installed on the peripheral side of the steel body. The steel body is heated through the electric heating device, and then the dry distillation carbon in the reaction furnace is heated through the steel body; in the descending process of the dry distillation carbon, the reaction furnace continuously heats the dry distillation carbon, when saturated steam input through the steam input port is jetted to the surface of the high-temperature dry distillation carbon,
