Abstract:
A boiler device 1 is provided with a bypass line (36) of which a one-side end and an other-side end are connected to the path of a fuel supply line (31), a bypass valve (37) arranged in the bypass line (36), and a control unit (61) which performs control for closing the bypass valve (37) during normal combustion and opening the bypass valve (37) to allow fuel gas to flow through the bypass line (36) as well during ignition of a burner (15), thereby making the amount of fuel gas supplied greater than the amount during normal combustion. The bypass line (36) is connected at the one-side end to the upstream side of a second orifice (35), and is connected at the other-side end to the downstream side of the second orifice (35).
