Waste Flue Gas Heat Exchanger Air Heat Exchanger

SGG flue gas heat exchanger is used in gasheating(pre-heating), cooling (pre-cooling), heat recovery and various other conditions. Itis based onworldleading technologyof laser welding pillow plate heat transfer design, with great technical advantages, including: high welding reliability, wide channel, small volume, high efficiency and easy to clean. In air to air heat exchang working condition, traditional heat exchanger is either with low heat exchanger rate, or can't effectively used because of large pressure drop, or almost impossible to deal with dust.Application:
Air heat exchange
Flue gas and air heat exchange
Flue gas heat recovery
Exhaust gas heat recovery
VOC exhaust gas heat recovery
ROT exhaust gas heat recovery
Heat exchange unit, etc.

The heat exchanger uses pillow plate, which is arranged according to certain distances. Inside plate is clean air channel, outside plate is gas (flue gas) channel. Distance between plates can be adjusted flexibly or designed according to working conditions. Pillow plate together with wide channel design not only makes high heat exchange coefficient possible, but also has technical advantages superior to traditional heat exchangers, including low pressure drop, high temperature and high pressure resistance and easy cleaning.

Laser welding pillow plate:
Heat exchange pillow plate is machined by full automatic laser welding and forming process. Its unique pillow structure makes fluid into optimum turbulence state to achieve high efficient heat exchange. It also boasts various advantages such as dust proof, high temperature and high pressure resistance and easy cleaning, etc.
Pillow plate concept:
Pillow plate is laser welded by two plates all around and in the middle area full of weld flowers. After the forming process, the inner part of the heat transfer plate forms a pillow type cavity. Pillow design creates excellent turbulence and provides self supporting structure. In practical applications, the additional welding path is often added in the pillow heat exchange plate, in order to adjust and control the flow of fluid into and out of the heat exchange plate nozzle position, the fluid velocity and flow rate inside plate, so as to optimize the heat exchange effect.
