Description

Boiler waste heat recovery device Technical Field The utility model relates to the field of boilers, in particular to a boiler waste heat recovery device. Background A large amount of waste heat can be generated in smoke generated during boiler operation, if the waste heat is not utilized, the waste heat can be dissipated into the environment in the form of cooling water and smoke, the environment is not damaged, the waste of resources is caused, in order to improve the utilization rate of the resources, the pollution to the environment is reduced, a waste heat recovery device is usually arranged at the smoke emission position of the boiler, the waste heat can be converted into available resources again through the device, so that the fuel cost is reduced, the cost is saved, the emission of greenhouse gases can be reduced, and the energy conservation and emission reduction targets of enterprises can be realized.
