Controlling the Thermal Structure of the Flame in the Furnaces of BKZ-210-140F Boilers with Single-Tier Frontal Arrangement of Multifunctional Burners when Burning Various Kinds of Fuel

摘要

We analyzed the integral characteristics and parameters pertinent to the burning of individual pul-verized-coal particles in a singled-out section of inflammation in the active burning zone of the furnace reactor of a boiler equipped with multifunctional burners arranged in a single-tier frontal manner. It is shown that poly-disperse and gas flames have reserves for stabilizing the thermal boundaries for inflammation and release of the main amount of heat. An algorithm is proposed for controlling the thermal structure of the flame when the coal-dust channels of the boilers are connected to hammer mills equipped with gravitational separators.
