Doosan Lentjes - Flue Gas Cleaning System

Circoclean`s advanced technology has been designed around the exacting demands of your WtE plant. Our processes have been developed to meet stringent emissions requirements and provide you with a robust and environmentally sound solution.

Circoclean forms part of our comprehensive range of world-class air pollution control (APC) solutions, encompassing dry and wet processes, together with fully integrated dedusting electrostatic precipitators (ESPs) and fabric filters.

• A compact, high performance and cost-effective reactor design — featuring no rotating or wearing parts — reduces investment costs and minimises your maintenance expenditure
• High flexibility to handle varying pollutant concentrations effectively, including sulphur dioxide, hydrogen chloride and hydrogenfluoride.
• An advanced process that minimises material consumption, water use and residues
• A simple, reliable process that meets all emission control and regulatory requirements

Pollutants are effectively eliminated thanks to a fluidised bed reactor combined with a downstream fabric filter for particulate separation.

1. Fresh additives enter the fluidised bed reactor, where hydrated lime is used to absorb acid pollutant and powdered activated carbon to adsorb heavy metals, as well as poly-chlorinated hydrocarbons such as dioxins and furanes
2. The bulk of the solid material is then re-circulated from the fabric filter to the fluidised bed, maximising the use of the additives
3. Water is injected to boost the absorption performance and to control the flue gas temperature
