Straightforward flue gas cleaning process

We understand that, when selecting suitable air quality control equipment for your business, low investment and operation costs are important criteria. Against this background, we have developed a straightforward and highly effective dry flue gas cleaning process called FER-DI® (Flexible Economic Reagent Direct Injection).

Applicable for typical pollutant concentrations

The process is a simple method to deal with moderate concentrations of harmful substances including acid gases, such as SOx, HCl, HF, as well as hydrocarbons, such as dioxins and furans and heavy metal, like mercury. Applications are possible in waste-to-energy facilities and downstream of coal, oil and biomass-fired boilers. Emissions regulations as per the European IED (Industrial Emissions Directive) and BREF (Best Available Techniques Reference) requirements can be reliably met.

Space-saving plant design

Depending on your individual needs, we either use sodium bicarbonate or hydrated lime as absorbent in combination with activated carbon, if required. The selected removal agent is directly injected into the hot flue gas passing through the ducting area downstream of the boiler. After this cleaning process step, the flue gas enters a downstream particle control device which can either be a fabric filter or an electrostatic precipitator (ESP). Solid particles are separated and partially fed back into the ducting area to improve the utilization of the reagent used.

The FER-DI® process benefits from a compact plant design featuring a particularly low footprint which reduces your investment costs. At the same time, the simple design allows the maintenance and operation expenditures to be minimal.
