Embodiment Construction
[0068] Below in conjunction with embodiment the present invention is described in further detail, described blast furnace hot blast stove gas is mixed by pipe network blast furnace gas and converter gas, based on heat balance formula: Q MG +Q A +Q DW -Q Fm -Q L =Q HB -Q CB Carry out the trial combustion of the large-scale blast furnace hot blast stove burning furnace control heat balance calculation; during the combustion period, perform real-time calculation of the physical sensible heat Q brought in by the mixed gas every second G , The physical sensible heat Q brought in by the combustion air A , The chemical heat Q produced by combustion DW , Physical sensible heat Q taken away by flue gas Fm . When the combustion is over, store the chemical heat Q produced by the combustion during each combustion DW , Input and output heat difference Q during combustion MG +Q A +Q DW -Q Fm value. During the air supply period, real-time calculation of Q per second B =Physica...
