Product Description
SGL flue gas heat exchanger is used in gas heating (pre-heating), cooling (pre-cooling), heat recovery and various other conditions. It is based on world leading technology of 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.
Application:
Flue gas and water heat exchange
Flue gas heat recovery
Exhaust gas heat recovery
VOC exhaust gas heat recovery
ROT exhaust gas heat recovery
Heat exchange unit, etc.
Design concept:
The heat exchanger uses pillow plate, which is arranged according to certain distances. Inside plate is fluid 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.
Performance advantages:
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.
Pillow plate Advantages:
Coal dust flue gas from 400ºC to 130ºC
Cooling medium: Circulating water
Energy recovery rate: 90%
With cleaning door
