<p><P>PROBLEM TO BE SOLVED: To provide a boiler apparatus capable of shortening time from start operation to steam supply, and of improving load responsiveness. <P>SOLUTION: The boiler apparatus includes a water tube disposed in a combustion chamber in a can body, a main burner for heating the water tube, a pilot burner for igniting the main burner, a pilot ignition means for igniting the pilot burner, a purge means for purging in the combustion chamber, a water level detection part for detecting a water level in the water tube, and a control part. The control part is configured to perform a purge S03 in the combustion chamber by the purge means, ignition of the pilot burner by the pilot ignition means, and ignition S10 of the main burner by the pilot burner in this order when start operation S01 has been performed, and is characteristically configured to perform ignition S10 of the main burner when the water level in the water tube detected with the water level detection part rises to a predetermined water level after the start operation S01 has been performed. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
