Abstract
PURPOSE: To prevent the degradation in thermal efficiency of a hot stove and operate a blast fuance smoothly by determining the quantity of heat to be charged from an expected rate of blast prior to start of combustion, the required quantity of heat extraction in correspondence to temp., the thermal efficiency with respect to the expected temp. at the change of blast temp., and the quantity of overheat or underheat of the furnace at the end of blasting.
CONSTITUTION: The required quantity of heat extraction H corresponding to an expected rate of blast Vb and a blast temp. Tb is determined by the equation I (N: cycle, i: hot stove No., Ch, Cc: hot and cold blast specific heat, Tc: cold blast temp., Ls: blast time). A change in thermal efficiency of the case when the blast temp. changes is beforehand formulated by a quadratic expression or a linear expression, and the expected thermal efficiency is determined by the equation II. Further, from the difference between the actually measured or estimated value Th(N-1, i) of the hot blast outlet temp. at the end of the previous blasting and the assigned blast temp., the quantity of the overheat or underheat accumulated in the furnace Δq is determined by the equation III, and the quantity of heat Q to be charged into the furnace at the combustion time of this time is determined from the equation IV.
