Description

Technical Field

[0001] This utility model relates to the field of waste heat boiler technology, specifically a waste heat boiler for a gas turbine generator set. Background Technology

[0002] In the smelting industry, waste heat boilers are used to recover the heat from the high-temperature flue gas discharged from the smelting furnace. In existing technologies, a refractory brick structure or a water-cooled water jacket structure is used between the smelting furnace and the waste heat boiler to form a sealed flue structure. The high-temperature flue gas discharged from the smelting furnace enters the waste heat boiler, which removes the heat energy of the high-temperature flue gas through heat exchange and delivers it to the end user.

[0003] In the event of an accident, existing waste heat boilers require the removal of the refractory brick structure, the insertion of a flue damper between the boiler's inlet and the furnace's outlet, the removal of the damper, and the reinstallation of the refractory material. Since the refractory material structure is disposable, this results in time-consuming maintenance costs. Therefore, we propose a waste heat boiler for gas turbine generator sets.
