Abstract

The present invention relates to a system for dry extracting / cooling heavy ashes and for controlling the combustion of high unburnt content residues, allowing to: extract heavy ash from the boiler bottom (12), foster and adjust post-combustion on the extractor belt (14) by combined use of comburent hot air and inert combustion fumes, already available in boiler, cool the ashes present on the belt and optionally re- circulating them - all or in part - in boiler, along with the fraction of light ashes of higher unburnt content.
