Among them, a discharge end 21 is provided on the wall surface of one lower end of the cylinder frame 2, and the discharge end 21 is connected to an external pipeline.

[0017] As can be seen from this embodiment, a high-efficiency heating furnace includes a base 1, a cylinder frame 2, a cylinder cover 4, a burner 5, and an exhaust pipe 6; A protruding combustion chamber 11 is formed on the base 1, and an installation reinforcement is formed inside the seat body below the combustion chamber 11.

The cylinder cover 4 is fixed to the cylinder frame 2 by threaded engagement.

[0018] The burner 5 is installed in the mounting cavity 12 and directly heats the combustion chamber 11. The heat transfer from the combustion chamber 11 directly heats the heat exchange chamber 3, which helps to improve the heating efficiency. Furthermore, the exhaust pipe 6 guides the exhaust gas generated during the combustion process into the heat exchange chamber 3, and exchanges heat with the solution in the heat exchange chamber 3 through the exhaust pipe 6, avoiding heat waste and achieving more efficient heat utilization.

[0019] The efficient use of heat generated by the burner 5 helps to save energy, and the multiple exhaust pipes 6 and the combustion chamber 11 located in the heat exchange chamber 3 can uniformly and efficiently heat the solution in the heat exchange chamber 3.
