The invention discloses a coal gas producer and a coal gas production method. The coal gas producer comprises a producer body, wherein the producer body comprises an oxidation zone and a reduction zone therein; the oxidation zone is communicated with a coal inlet and an air inlet, the coal inlet and the air inlet are respectively filled with coal and air for combustion oxidation reaction, so thatcarbon dioxide can be generated; the reduction zone is communicated with a reduction coal inlet, and reduction reaction is carried out on reduction coal introduced from a reduction coal inlet and carbon dioxide generated from combustion to generate carbon monoxide. In the technical scheme of the invention, the combustion oxidation reaction and reduction reaction during the coal gas production reaction process are respectively and fully carried out, and temperature can be respectively controlled to promote the oxidation reaction and the reduction reaction to be carried out fully, thereby improving the combustion efficiency of coal and reducing resource consumption.
