Description

Technical Field

[0001] This utility model relates to the field of boiler waste heat recovery technology, and in particular to a waste heat recovery structure for industrial boilers. Background Technology

[0002] An industrial boiler is a closed, pressurized thermal device used for non-power generation purposes such as industrial production, heating, and steam supply. It converts the chemical energy of fuel into thermal energy, and then heats water into steam or hot water.

[0003] In existing industrial boiler waste heat recovery structures, the water storage tanks are mostly fixed installations. When the exhaust gas from the flue enters the tank, the heat is concentrated in a local area of ​​the water storage tank, resulting in uneven heating of the tank surface and slow water temperature rise, which significantly reduces the waste heat recovery efficiency. In addition, the inner wall of the tank and the surface of the water storage tank are prone to the adhesion of dust and other impurities, which will hinder heat transfer and further weaken the heat exchange effect.

[0004] Therefore, it is necessary to provide a new waste heat recovery structure for industrial boilers to solve the above-mentioned technical problems. Utility Model Content
