Abstract
Claims
1. A heating boiler with built-in air preheating flue, comprising a heating boiler (1), a smoke exhaust pipe (2) is fixedly installed at the smoke exhaust end of the heating boiler (1), characterized in that: The other end of the exhaust pipe (2) is fixedly installed on the top of the preheating box (3). The preheating box (3) is equipped with a heat-conducting box (4). The heat-conducting box (4) is filled with a heat-conducting medium. Several heat-conducting pipes (5) are also fixedly installed inside the heat-conducting box (4). The upper ends of the heat-conducting pipes (5) are connected to the exhaust pipe (2). The lower ends of the heat-conducting pipes (5) pass through the heat-conducting box (4) and are connected to the second exhaust pipe (6). An air inlet (7) is opened on the front of the preheating box (3). A heat-absorbing pipe (8) is provided between the two heat-conducting pipes (5) inside the heat-conducting box (4). One end of the heat-absorbing pipe (8) is connected to the center of the side of the heat-conducting box (4) away from the air inlet (7). The other end of the heat-absorbing pipe (8) is connected to the air outlet pipe (9). The other end of the air outlet pipe (9) is connected to the air inlet of the heating boiler (1).
2. The heating boiler (1) according to claim 1, characterized in that: The preheating box (3) has a flow shroud (10) on one side near the air inlet (7), and the heat conduction box (4) has heat conduction fins (11) on each side of its outer surface.
3. The heating boiler (1) according to claim 1, characterized in that: The heat-conducting fins (11) on the front of the heat-conducting box (4) are distributed radially with the lower side of the flow-concentrating hood (10) as the center.
4. The heating boiler (1) according to claim 1, characterized in that: The preheating box (3) has a filter screen (12) inserted at the air inlet (7) on the front side, and the outer wall of the heating boiler (1) is provided with a groove (13) that matches the size of the filter screen (12).
5. The heating boiler (1) according to claim 1, characterized in that: The top of the inner wall of the heat-conducting box (4) is provided with a diversion plate (14), and the upper ends of several heat-conducting pipes (5) are connected to the exhaust pipe (2) through the diversion plate (14).
6. The heating boiler (1) according to claim 1, characterized in that: Both the heat-conducting pipe (5) and the heat-absorbing pipe (8) are serpentine pipes.
7. The heating boiler (1) according to claim 3, characterized in that: The distribution of the heat-conducting fins (11) on the outside and back of the heat-conducting box (4) is adapted to the distribution of the heat-conducting fins (11) on the front of the heat-conducting box (4).
