Blast furnace performance data

Mass and energy balances are used to evaluate blast furnace performance. Many companies now use sophisticated computeri2ed data acquisition and analysis systems to automatically gather the required data for daily calculation of the mass and heat balances. Typical mass and heat balances are shown in Figure 4 and Table 5, respectively. 

Derived performance data for the sinter plant-blast furnace (100 000 t/a of lead). 

Cupola furnaces In cupola furnaces, a massive surplus of chlorine is always present from coke. Enough carbon is present from coke too, but an additional input of carbon may be needed the event of caused by poor scrap qualities. Under specific operational conditions, the conditions for dioxin formation could occur. Since de novo synthesis mainly occurs during cooling of the flue-gas, this applies to both hot blast and cold blast cupolas. In Table 3.34, the result of a statistical analysis of all the measurement data from Table 3.33 for CBC and HBC is given. Whereas Table 3.33 presents average values per plant, for Table 3.34 individual measurements were used to perform an overall analysis.
