A first insulation layer is provided on the inner wall of the shell 1 to reduce heat loss inside the shell 1.

[0026] A filter box 4 connects the inlet of the exhaust pipe 2 and the exhaust outlet of the chimney 18.

[0029] Working principle:

[0030] like Figures 1-5 As shown, when the heat energy recovery and utilization device is in use, the high-temperature flue gas generated by the thermal oil boiler 17 enters the flue gas inlet pipe 6 through the chimney 18, and then enters the filter box 4 through the flue gas inlet pipe 6. The filter screen 5 filters out the dust particles in the flue gas. The filtered flue gas enters the exhaust pipe 2. During the process of water flowing inside the heat-conducting pipe 3, the water will exchange heat with the flue gas, thereby raising the temperature of the water. The heated water then enters the water inlet pipe 13 through the heat-conducting pipe 3, and finally enters the steam furnace 16, realizing the preheating of the water entering the steam furnace 16, recovering and utilizing the heat energy of the flue gas, reducing the waste of heat energy of the flue gas, and reducing energy consumption costs.
