The present invention relates to a system for extracting and recovering energy for large for large flows of heavy ashes produced by solid fuel boilers, able to decrease the final temperature of the extracted ash without increasing the air flow entering the boiler flue, usually fixed by the boiler designers at a value around 1.5% of the total combustion air. When the air flow needed to the cooling ...

Process for producing cellulose-based thermal and/or acoustic insulation material, characterised in that said insulation material comprises paper sludge and wherein said insulation material is in form of flakes.

Nanosized filamentary carbon structures (CNTs) nucleating over a catalyzed surface may be grown in an up-right direction reaching a second surface, spaced from the first surface, without the need of applying any external voltage source bias. The growth process may be inherently self-stopping, upon reaching a significant population of grown CNTs on the second surface. A gap between the two surfaces...
