Flue gas treatment by dry scrubber
Leaving the combustion chamber, the gases return to the post-combustion chamber at a minimum temperature of 850 °C and contain pollutants. The principle of our dry scrubber consists of limestone.
Through these layers of stones, the pollutants are filtered and neutralized. After the dust has been filtered and purified, the flue gases are transported through the stainless-steel chimney. Our system is very simple and robust in order to avoid heavy investment and a high cost of use and maintenance, while having improved gas emission analysis results compared to a solution without scrubber.
Main advantages of the reactive stone filter:
Trapping dust, heavy metals, chlorine, fluorine and sulphur at the same time.
Dry treatment eliminating the problem of water treatment.
Low cost of the reagent (limestone).
Operation without fear regarding a rise in temperature at the inlet of the filter.
Lower operating cost due to virtually no maintenance and low cost of the reagent.
This filter consists of a cell made of factory-premade metal sheet with a refractory lining.
This cell is filled with reactive stones.
The entire structure is made of E24 steel and covered in the factory with a coat of finishing paint.
The recycling and regeneration kit for reactive stones is manual.
The stones are recycled every three or six months depending on the duration of use and the composition of the waste.
A first stainless-steel filter is located at the inlet of the filter and a second filtration at the outlet of the filter.
