Embodiment Construction
[0062] The first embodiment of the present invention, such as figure 1 As shown in the coupled fixed bed oxygen-enriched continuous gasification process, the solid raw material is coal, and the process is to mix oxygen and air to form oxygen-enriched air, then blow in oxygen-enriched air and steam to produce semi-water gas; the gas-making furnace includes a 1, B, two ordinary gas furnaces, the bottom of A furnace is connected with oxygen-enriched air valve A1, steam valve A3, gas valve A5, and the bottom of B furnace is connected with oxygen-enriched air valve B2, steam valve B4, and gas valve B 6; the gas outlets on the top of furnace A and furnace B are connected in parallel with gas valve C 7, and the other end of gas valve C 7 is connected with the other end of gas valve A 5 and gas valve B 6 through a four-way joint. The other end is connected to the output pipe.
[0063] The cycle time of the gas-making process is 120 seconds, the oxygen concentration in the oxygen-enri...
