AI Technical Summary
Traditional steam boilers are inefficient in waste heat recovery and have long downtime during maintenance, which affects equipment operating efficiency.
A spiral heat recovery pipe and a delivery pipe are used to form a sleeve structure. Combined with heat-conducting materials and insulation layers, the heat exchange area and efficiency are increased. The system is also connected to a flow divider and a flexible hose for easy maintenance.
It improves waste heat recovery efficiency, reduces equipment downtime, and enhances the continuity and efficiency of equipment operation.
