Industrial Aerodynamics

Mixing of different Gas Flows

• Gas flow of different temperature or/and different kind
• Ammonia with flue gas in DeNOx plant
• Solid particles within the gas flow, e.g. sorbents, ACI

Flow Homogenization and Flow Guidance

Homogenization and guidance of the flow is important for the correct function of downstream aggregates, like air heater or catalysts. This can be achieved with optimized turning vanes and especially with our static mixer system.

Reducing Pressure Loss

Fan power consumption can be lowered by reducing the pressure loss of the flow. This can be achieved by better duct geometries, by optimized turning and guide vanes and our static mixer system.

Aeroacoustic

Aeroacoustic problems may arise by enduring vortex shedding (Kárman vortex street) and by resonance effects in the flow space. These problems can be avoided in most cases by theoretical considerations.

Dust Flow Homogenization

Dust settlements can occur in plants with dust containing flows. They can be observed mostly at parts of the plant with horizontal ducts and low flow velocity respectively at wake zone behind flow separations. Flow modell tests help to identify such settlements. With our mixing plates these dust settlements can be reduced even totally.

Avoiding visible Plumes at Cooling Towers

Visible plumes at cooling towers are often an environmental and political topic. In some cases the wet plume can cause ice on nearby streets in winter time. In order to avoid these visible plumes hybrid cooling towers can be applied. Within such cooling towers wet and dry air must be mixed so that no condensation occurs at the fan stack outlet. The mixing must be realized within a very short distance. Model tests are performed in order to determine the best mixing device arrangement for the actual cooling tower type.
