FLAME FURNACE AND METHOD FOR REGULATION OF BURNING The Fiery Furnaces

摘要

1. A method of operating a combustion furnace comprising a combustion chamber (2), wherein: - the main oxidant is injected at a controlled rate into the combustion chamber (2), - the combustible material is burned in the combustion chamber (2) with a main oxidant, producing heat in a combustion chamber energy and the flue gases (6) at a temperature above 600 ° C, - obtained as combustion gases (6) is withdrawn from the combustion chamber (2) via the branch pipe (13), said reserved flue gases (6) may contain residual oxidizable substances, and wherein the outlet pipe (13) is provided with an input (14) diluted nogo oxidant for the combustion chamber (2), - combusted residual oxidizable substances with diluting the oxidant in the flame (12) in the branch pipe (13) on the input level (14) for diluting the oxidant, characterized in that: - the detector determines the intensity of said flame inside the branch pipe (13), - regulate the administration rate of the main oxidant into the combustion chamber (2) depending on the set intensity plameni.2. A method according to claim 1, wherein: - reduce the rate of introduction of the main oxidant into the combustion chamber (2) when the flame intensity is set below a predetermined lower limit, and- increase the speed of the main oxidant injected into the combustion chamber (2), when the installed flame intensity above a predetermined upper predela.3. A method according to claim 1, wherein: - reduce the rate of introduction of the main oxidant into the combustion chamber (2) when the flame intensity is set below the lower limit during a predetermined period of time Δt1, or when the mean value of the intensity of the flame established within a predetermined period Δt1 below the lower limit u increase the rate of centuries
