Additive Conditioners
Luhr Conditioning Rotor (patented) and Dust Re-circulation Systems:
Conditioning rotors are installed as part of dust re-circulation systems. A proportion of the collected dust is returned to the inlet of the plant where it is fed into incoming gas stream then into the conditioning rotor. The object of the rotor is:
1. To increase the utilisation of reagents added for acidic adsorption.
2. For very adhesive particulate to promote agglomeration with conditioned filter dust.
How large is a nanogram?
It is difficult to perceive the magnitude of a nanogram. The analogy below brings this into perspective.
Local to our parent company in Germany is a lake. This lake has surface area of about 30km and an average depth of 2 metres.
The volume therefore = 60,000,000m3.
A cube of sugar weighs 2 grams, or 2,000,000,000ng. If this cube of sugar were dissolved in the lake and homogeneously distributed the concentration would be 33ng/m3.
From the above diagram dependent on applications and inlet concentration it can be seen that emission concentrations of between 0.15 and 0.02ng/Nm3 are achievable
