摘要： A burner includes a first burner port that generates a first flame, a gap that surrounds the first burner port, and a plurality of second burner ports that are disposed on either side of the gap, the second burner ports generating second flames to hold the first flame. The first burner port combusts a first mixture (lean mixture) to generate the first flame (lean flame). The first mixture includes air more than fuel gas. A gap that surrounds the first burner port is formed. A plurality of the second burner ports are arranged on either side of the gap. The second burner ports combust a second mixture (rich mixture) to generate the second flames (rich flames) and hold the first flame. The air-fuel ratio of the second mixture is smaller than the first mixture.

摘要： A method of controlling a proportional solenoid valve whose valve opening degree is controlled by excitation of a proportional solenoid includes: generating a driving current (id) that excites a proportional solenoid (28); reversing a polarity of the driving current (id) at a cycle faster than movement of a valve body (18); and controlling the valve opening degree by a current level of the driving current (id). As a result, an alternating magnetic field is generated in the proportional solenoid so that a desired valve opening degree is obtained by the driving current level while obviating the influence of the residual magnetism.

摘要： A burner includes plural burner ports that produce flames using a first air-fuel mixture and plural auxiliary burner ports that are disposed in a circumference of the burner ports, the plurality of the auxiliary burner ports producing an auxiliary flame using a second air-fuel mixture whose an air ratio is different from an air ratio of the first air-fuel mixture. The air ratios of the first air-fuel mixture and the second air-fuel mixture are each higher than 1.
