PURPOSE:To reduce the consuming quantity of fuel oil by a method wherein combustion conditions are determined by fine pressure oscillation in combustion and atomizing quantity is controlled to keep the best combustion condition. CONSTITUTION:Pressure in a furnace is detected by a detector 6, wave form analysis of fine pressure oscillation in combustion is carried out by a frequency analyser 18, energy distribution of frequencies for the fine pressure oscillation in combustion is determined, compared with the oscillating energy ratio which has been established previously by an oscillating energy regulator 19 and atomizing quantity is controlled by regulating a flow rate regulating valve 23 according to the deviation signals. Thus, the best combustible condition can be kept in the furnace and the consuming quantity of fuel oil can be reduced. |
