A plurality of stove core fire outlet hole lugs are arranged on the stove core, stove core fire outlet holes are arranged on each of the stove core fire outlet hole lugs, and a stove core air inlet channel is arranged between adjacent stove core fire outlet hole lugs. A plurality of fire cover fire outlet hole lugs are arranged on the fire cover, fire cover fire outlet holes are arranged on each of the fire cover fire outlet hole lugs, a fire cover air inlet channel is arranged between adjacent fire cover fire outlet hole lugs, and the direction of fire outlet position of the stove core fire outlet hole faces the channel opening of the corresponding fire cover air inlet channel. With the flames of the stove core and the flames of the fire cover being crossed by the alternating arrangement of the fire outlet holes, the air contact area is enlarged such that the heat efficiency is improved.
