The availability factor of a power plant is the amount of time that it is able to produce electricity over a certain period, divided by the amount of the time in the period. Occasions where only partial capacity is available may or may not be deducted. Where they are deducted, the metric is titled equivalent availability factor (EAF). The availability factor should not be confused with the capacity factor. The capacity factor for a given period can never exceed the availability factor for the sam… WebGenerally, the AOD is combined with the EAF to produce the stainless steel and the raw materials of the EAF are only the scrap and the ferro-alloy. In this way, the power consumption of the EAF (about 450 kwh/t) is higher and the melting duration of the EAF (75 min to 80 min) is longer. To further decrease the power consumption of the EAF and ...
