Description

Technical Field

[0001] The utility model relates to the technical field of steam boilers, in particular to a waste heat circulation device for a steam boiler. Background Art

[0002] A steam boiler refers to a boiler equipment that produces steam. Its design, production, factory delivery, and installation must be subject to supervision by the national technical supervision department. Users need to obtain a boiler use license to operate the boiler. A steam boiler heats and vaporizes the water inside the cylinder through a burner, and transports the hot steam through pipes to the required location.

[0003] Existing steam boilers can only heat and vaporize water and transport the hot steam through pipelines to the required places. There is no effective way to recover the waste heat contained in the used hot steam. In addition, the existing waste heat recovery only recovers the waste heat contained in the hot steam, and cannot simultaneously recover the waste heat in the flue gas generated by the fuel used to produce the hot steam.

[0004] To this end, we propose a steam boiler waste heat circulation device. Utility Model Content
