Abstract:
     The present invention is related to a method and stove for producing double flow direction exchanging gas. It uses steam or mixed air and steam as two different gaseous media, led separatively from upper and lower ends of the moving bed layer, and the direction is changed every 2-5 minutes. On the lower and upper ends of its moving bed, there are inlets of gaseous media respectively, while the gas flows out of the outlet between the inlets of gaseous medium at the upper and lower ends. The stove according to the present invention is simple and reasonable in structure. Because oxygen is not used as a gaseous medium, the gas-producing system is also simplified, and the investment cost is lowered. Owing to a double flow direction exchanging gas generation, the gaseous intensity is doubled as compared with that of unidirectional.
