<p>BLAST FURNACE CONTROL METHOD A method for maintaining a uniform stable operation of a blast furnace susceptible to erratic behavior because of large disturbances introduced into the furnace is described. The method includes: (a) determining a high temperature heat parameter (HTH) over a predetermined period of time, (b) determining a CEEP parameter over a predetermined period of time, (c) comparing the differences between the HTH and the CEEP parameters and their respective averages during selected time periods of operation, and (d) changing the temperature and/or moisture content of the hot blast air dependent upon the values in step (c).</p> |
