FIELD: process engineering.
SUBSTANCE: invention relates to combustion processes, particularly, to methods of decreasing content of mercury or sulfur in flue gases emitted in atmosphere. Method of combusting mercury-bearing fuel in fuel combustion furnace unit comprises adding the composition of main sorbent to fuel before feed into furnace, said composition including bromine or iodide. It includes feed of said fuel into said furnace with added composition of the main sorbent. It comprises also addition of extra sorbent components containing calcium, silica and aluminium oxide into said furnaces at over 1093°C to burn said fuel to form combustion product gases, ash and heat energy. Invention covers also versions of the method of combustion and reduction of mercury content in flue gases.
EFFECT: resulted ash of high cementing properties and not leached with respect to metals.
