摘要： PURPOSE:To enable the optimum operation of a plurality of rotors such as soot diffuser by readily setting or altering the operating speeds of the respective diffusers at every one as required. CONSTITUTION:Start signals 121, 191 are outputted from a soot diffuser starter 111. A start signal 121 operates an inverter 3 as a start signal 14 through an OR gate 13. The start signal 191 selects frequency setters 151-15n preselected by a shortcircuiting pin 151 in a pinboard 25, outputs corresponding frequency set signals 161-16n, and inputs to the inverter 3 as a frequency set signal 18 through an OR gate 17. A start signal 191 operates an electromagnetic contactor 61 to energize an induction motor 81 by the output of the inverter, thereby operating the soot diffuser 91. The operations of other soot diffusers 92-9n are executed in the same procedure as the operation of the diffuser 91.
