Fcc Heat Recovery Boiler B


vacuum water boiler t6

The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.


water tube steam boiler

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

4-4 Recovery Boiler Chemical Principles

Article Summary. Hot spots on FCC units are a common occurrence but relatively little is known about the implications for long term operation. Standard procedures in a FCC plant are to monitor on a scheduled basis the thermal scans of their equipment and use steam to cool if hot spots exceed a certain temperature threshold.
