Following an inspection at the final customer’s site abroad, Tecnosida® designed a three-stage system. The first stage would separate the larger dust particles, the second stage those of medium size and the third stage the finest ones.
To achieve this goal, the following specific components were selected and/or designed:
- Pre-separation system downstream of the boiler (after the first combustion) with recovery of the unburnt residue and its return to the combustion chamber;
- Second stage of cyclonic separation at the boiler exhaust;
- Third mechanical filtering stage with the Dustdown®biomass model to remove the finest dust particles.
The proposed solution has the advantage of lightening the load on the cyclone, which can therefore be smaller given the reduced dust load to be treated.
