The technical solution of the invention is as follows: the furnace comprises a furnace body with water jackets on the upper wall and the peripheral walls, a vertical water jacket partition plate which divides the furnace body into a front combustion chamber and a rear combustion chamber is arranged in the furnace body, a fire grate is arranged below the front combustion chamber, an ash receiving drawer which is slidably arranged on the furnace body is arranged below the fire grate, a cooking range opening is arranged on the top wall of the furnace body above the front combustion chamber, an air supply opening and a furnace opening are arranged on the front wall of the furnace body above the fire grate, a smoke outlet is arranged on the upper part of the rear wall of the furnace body above the rear combustion chamber, a front combustion smoke outlet is formed by spacing the upper edge of the vertical water jacket partition plate from the top of the front combustion chamber, a back combustion smoke outlet is formed by spacing the lower edge of the vertical water jacket partition plate from the back of the fire grate, a front combustion switching turnover plate matched with the front combustion smoke outlet is arranged in the rear combustion chamber, a horizontal air distribution box with the upper side height corresponding to the upper, The vertical water jacket partition plate, the left furnace body wall and the right furnace body wall are respectively connected, the horizontal air distribution box is communicated with an air supply port on the front wall of the furnace body, a stove fire hole is arranged at a position, corresponding to a stove mouth, on the horizontal air distribution box, a plurality of air distribution holes are arranged on the side wall of the horizontal air distribution box at the stove fire hole, a plurality of water pipes with left and right ends respectively communicated with water jackets on the left and right side walls of the furnace body are arranged in the rear combustion chamber, a horizontal air distribution plate positioned behind a fire grate is arranged below the rear combustion chamber, a plurality of lower air distribution holes are arranged on the air distribution plate along the vertical direction, an air distribution port is arranged on the side wall of one side of the furnace body below the air distribution plate, a high-temperature-resistant smoke baffle plate is arranged in the rear combustion chamber along the horizontal direction, the front edge of the high-temperature-resistant smoke baffle plate is connected with the.
The invention has the technical effects that: the distributed air positions are dispersed, large-range combustion supporting is facilitated, the distributed air temperature is high, the combustion supporting effect can be improved, firepower is concentrated when cooking is conducted, a cooker can be heated quickly, smoke and fire stay in a boiler for a long time, and heat exchange and dust settlement are facilitated. The cooker can concentrate firepower and have stronger firepower when cooking and has better heating effect. Form the high temperature combustion district during the back-burning heating, combustible flue gas burning is more abundant, and the time of dwell in the boiler is longer, and the dust subsides the effect better, and the exhaust flue gas is cleaner. It is more energy-saving and environment-friendly, and the using effect is more ideal.
During reverse combustion, the air distribution plate replaces the originally designed gasification pipe, air distribution is more uniform, and air distribution with higher temperature can be provided. The added high-temperature resistant smoke baffle prolongs the retention time of the combustible flue gas in the area to form a high-temperature combustion area, so that the combustible flue gas can be more fully combusted under the combustion supporting of high-temperature air distribution, the flow rate of smoke dust is reduced, and the sedimentation effect is also played.
