PURPOSE:To perform control of combustion by providing a light detector along the longitudinal direction of flame and controlling the supply of fuel to the combustion part depending on whether there is optical information or not. CONSTITUTION:When an unstable blow off phenomenon like flame 7 occurs, only those designated by 20 and 21 among optical fibers receiving light. In this case, a control signal generator 28 detects that the combustion is an unstable state and displays it on a display unit 29, and restores the combustion to a normal combustion state by detecting the set condition of a fuel supply adjuster 2. Despite that the fuel is supplied, if there is no optical information of all the optical fibers, this shows a dangerous state of flame being extinguished. Therefore, it is displayed on the display unit 29 that the combustion is in a dangerous state, and the fuel adjuster 2 is controlled to stop the supply of the fuel. By this precedure, warning of blow off is displayed and restoration to the normal state is enabled, and stop of fuel supply is performed by detecting the extinguishment of fire. |
