<p>PROBLEM TO BE SOLVED: To properly perform combustion control in combustion start of a heat source machine having a combustion mechanism combusting sprayed liquid fuel.SOLUTION: In a combustion burner, a combustion amount is controlled according to an ignition pattern regulating initial combustion numbers Ga, Gb to ignition, in combustion start. When applying ON/OFF combustion control in which a combustion period with spray of a constant fuel amount and a combustion stop period are alternately provided, in combustion start according to detection of minimum operation flow quantity (MOQ), compared to time of combustion start for resuming combustion operation from combustion stop (Gb=G1), a combustion amount in an ignition pattern is increased (Gb=G2).</p> |
