The present invention relates to a forward-and-reverse-
flame type producer for the coproduction of
biomass gas and carbon and a relevant gas-carbon coproduction method, which belong to the technical field of energy-recycling. The producer comprises a gasification furnace and a
carbonization chamber; wherein, the upper part of the gasification furnace is a reverse-
flame gasification furnace chamber, and the lower part is a forward-
flame gasification furnace chamber; the bottom of the reverse-flame gasification furnace chamber is communicated with the forward-flame gasification furnace chamber through a reverse flame gate; and the forward-flame gasification furnace chamber is adjacent to the
carbonization chamber and is communicated with the
carbonization chamber through a channel. When the producer is used, biomasses are respectively fed into the producer to be burnt, and the
flammable gas produced by the reverse-flame gasification furnace chamber is mixed with the
flammable gas produced by the forward-flame gasification furnace chamber through the reverse flame gate and then enters into the carbonization chamber. Finally, the flammable
biomass gas passing through the carbonization chamber can be pumped out, and
biomass carbon is obtained as well. The producer can increase the gasification intensity and heat value of the
flammable gas and avoid overburning caused by boiling
combustion, thus producing high-heat-value flammable gas meeting requirements as well as carbonized substance replacing
charcoal.
