Dry desulphurization
Supportive cooling and humidification of flue gas
A fine-grained reaction material (e.g. hydrate plus additives such as activated carbon) is fed via a circulating dry scrubber (CDS). The fine-pored structure of the surface binds the SOx but also other acidic components such as HCl and HF from the flue gas.
Additionally, water is injected into the fluidized bed reactor to cool the flue gas to the optimum reaction temperature and to humidify the reaction material.
Our solution
For the injection into the circulating dry scrubber mainly spillback nozzle lances are used. Due to the local and process-related conditions, they are equipped with a protective tube and optionally with barrier air. In order to increase the service life, wear protection e.g. in the form of a half-shell, is also recommended.
Together with the injection system, we offer you the optimum solution for your process requirements.
