Abstract:
To shorten a time necessary for start control, in a burner having a wick for holding fuel.SOLUTION: A burner 22 comprises: a combustor 23 having a first chamber 31 and a second chamber 32; a fuel supply part 40; an air supply part 45; a wick 39 for holding fuel; an ignition plug 50 having a heat generation part 51; a first temperature sensor 53 for detecting a first temperature of the first chamber 31; a second temperature sensor 54 for detecting a second temperature of the second chamber 32; and a BCU 60 for controlling the burner 22. The BCU 60 includes, in start control, warmup processing for increasing an air supply amount by the air supply part 45 and a fuel supply amount by the fuel supply part 40 up to target values at a constant quantity ratio after the ignition of the fuel held by the wick 39, performs cold start control when the first temperature is lower than a cold temperature, and when the first temperature is not lower than the cold temperature, performs first start control in which an increase speed of the fuel supply amount in the warmup processing is higher than that at the cold start control.SELECTED DRAWING: Figure 1
