摘要

Integrated system for the extraction of heavy ashes, conversion of light and matter reduction in ash unburned.The present invention relates to a process for the treatment of all the ashes produced by burning of coal boiler (1), capable of reducing the total content of unburned material, to increase the efficiency of combustion by the boiler (1), and presenting the ash light as the only The residue which is formed from the combustion of coal.In particular, the process provides for the extraction of heavy ashes (4) from the bottom (23) of the boiler, the ash from the hoppers of economisers (5) and the fraction of light rich in ash unburned material from the filters (11) used to collect dust from gas flowing, DIT The ash is mixed in the silo (15).Adjusted in proportion and transferred to one or more hoppers (17) of the mills (18), and being returned to the boiler (1) after having been mixed with coal by means of the burners (2).
