Flue gas circulating combustion type coal-fired cooking stove

The invention discloses a flue gas circulating combustion type coal-fired cooking stove. A lining barrel (106) made of asbestos is installed in an inner cavity of a coal-fired stove body (109) of the flue gas circulating combustion type coal-fired cooking stove in a sleeved mode. An asbestos air barrel (103) is installed in the asbestos lining barrel in a sleeved mode. When an air blower (117) is started, a valve plate (120) is opened, and a valve plate (121) is closed, flue gas in the cavity of the coal-fired stove body enters an air blowing pipeline (112) through a connection pipeline, a flue gas hopper (116) and a flue gas circulating pipeline (115) and is mixed with supplied air of the air blower; the mixed flue gas is converted into ascending rotating air after passing the air blowing pipeline (112), a vertical pipe (104) and a guider (110), then passes the gaps of stove teeth (111) and enters a combustion cavity for auxiliary combustion; and circulating is conducted in this way, and smoke ash produced i
