The invention discloses a vertical low-carbon and energy-saving counter burning furnace, which comprises a vertical counter burning furnace
pipe and a large horizontal furnace
pipe. The vertical counter burning furnace
pipe is arranged on the middle lower part in a counter burning furnace body, the vertical section of the vertical counter burning furnace pipe is inverted-'T'-shaped, the large horizontal furnace pipe is arranged on the middle upper part in the counter burning furnace body, the two furnace pipes are communicated with each other by a plurality of straight fire tubes surrounding the upper part of the vertical counter burning furnace pipe, a
flue is arranged on the top of the horizontal furnace pipe and penetrates through the top of the counter burning furnace body to form an afterheat
flue outlet, a
smoke back-
combustion type afterheat apparatus is arranged on one side of the counter burning furnace body and consists of a body and a container, an afterheat
flue inlet is formed in the top of the
smoke back-
combustion type afterheat apparatus and is communicated with the afterheat flue outlet via a flue connecting tube, inverted-fan-shaped water tubes are transversely placed in the vertical counter burning furnace pipe, and horn-shaped water tubes are vertically placed in the horizontal furnace pipe. The invention has the advantages that vertical low-carbon and energy-saving counter burning furnace is compact in structure, high in
thermal efficiency, stable in performance and easy to popularize and use, and gasification and
combustion are performed directly, the height of the furnace body is selectable, secondary
pollution is avoided during dust removal,
smoke discharge meets requirements on environment friendliness, and the like.
