AI Technical Summary
Traditional boiler waste heat recovery devices have low heat exchange efficiency, significant heat loss, and are difficult to clean and maintain, resulting in energy waste and increased operating costs.
A waste heat recovery device was designed, comprising a boiler body, a flue gas outlet, a support frame, a hydraulic push rod, a water tank, heat pipes, and baffles. By setting heat-conducting fins at the top and bottom of the heat pipes, setting sliding grooves and slots in the support frame, using insulation cotton and sealing gaskets, and setting staggered air guide plates in the flue gas pipes, the heat transfer efficiency, stability, and cleanliness of the device are improved.
It achieves efficient heat transfer, reduces heat loss, facilitates cleaning and maintenance, improves energy utilization efficiency, and reduces operating costs.
