Abstract: The present disclosure provides an emergency power system for a bottom blowing furnace and a bottom blowing furnace equipment. The emergency power system includes a battery and a drive controller. The drive controller has a frequency converter and a controller. The frequency converter is configured to convert a direct current input from a DC input interface or an alternating current input from an AC input interface into a variable-frequency alternating current, and to output the variable-frequency alternating current via an AC output interface for providing an emergency power supply to a load of the bottom blowing furnace and controlling a speed of the load. When the city power grid is cut off, the controller controls the frequency converter to switch to the DC input interface, such that the battery inputs the direct current to the frequency converter and the frequency converter converts the direct current to the variable-frequency alternating current.
