Abstract

PURPOSE:To enable to increase the efficiency of the system as a whole, by stopping a fan during combustion by utilizing pulsation produced at the time of combustion. CONSTITUTION:Plusating combustion is taken place in the combustion chamber 4 of a burner 1 when combustion gas is ignited. Combustion air is automatically fed into the combustion chamber 4 by the pulsating flow, passing through a fan 9, a silencer 8 and a plenum chamber 7, so that it is not necessary to drive a fan 1 at the time of combustion. Flames produced at the time of combustion is detected by a flame rod 6 and a signal is fed into a controller 15. The signal makes a switch 16 and a switch 17 turn OFF and an ignition plug 5 and the fan 9 are stopped by the switches respectively, but combustion is continued by the effect of automatic combustion by pulsating combustion. if the air is insufficient during steady combustion, flames are immediately extinguished because the ignition plug 5 and the fan 9 are stopped at the same time, although flames are detected by the flame rod 6.

is activated, and new air is introduced into the combustion chamber of the pulse burner l through the air supply chamber 7 and the air supply hole /lI,
The combustion chamber is filled with fresh air. The time required to fill with this new air is set as the air blowing time calculated from the fan blowing capacity. When this set time elapses, the control device 3 is activated and the solenoid valve 3 is opened, and the fuel gas is is introduced into the combustion chamber q via the fuel chamber 10, and the fuel gas and fresh air are mixed. At the same time, the spark plug switch /6 is turned on, and the spark plug j
is ignited and ignites. When the combustion gas ignites, the burner
Pulsating combustion occurs within the combustion chamber. This pulsating motion causes the combustion air to become a fan? , through the muffler tube and the air supply chamber 7 into the combustion chamber 7, so that there is no need to operate the fan 1 during combustion.
