Description

High-temperature flue gas heat exchange device

Technical Field

The utility model relates to a high temperature indirect heating equipment technical field specifically is a high temperature flue gas heat transfer device.

Background

Most of the existing burners are directly heated by flame generated when gas and air are combusted, so that the heat generated by the flame from the burner is not completely absorbed by a heated object, mostly lost to the outside air, and insufficient combustion of the heated object, which causes low heat efficiency, and the flue gas after combustion has extremely high temperature, and the direct emission not only causes air pollution, but also causes waste of a large amount of energy. The temperature of the discharged flue gas can be greatly reduced by utilizing the heat exchange method of the combusted high-temperature flue gas, so that the energy can be recycled.
