Flue gas, leaving the boiler in which its boiled down to remove minerals, is conditioned by mixing with the first stage hot air before the treatment. One part of the second heating stage air flow is mixed with a fuel and fed to the furnace for combustion. The other part of the said air flow is used to carry dry minerals, withdrawn from flue gas, to the furnace. Air-fuel mixture is delivered to the furnace upper part. Dry minerals and boiled waste are fed together with air flow to the combustion zone located in the furnace lower part. Air- fuel mixture is directed to the above-melt zone to supplementary burn underburnt products.
