Title: Combustion controller
Inventor: IMAI HIROHISA
IPC: F23N5/12
Filed: 1990-09-21
Abstract: PURPOSE:To correctly judge normal combustion or abnormal combustion and secure the safety by providing two levels of a set volume of excess air and set volume of excess fuel that are beforehand specified and adopting either one of them as a set value by the signal from a combustion controller and stopping the fuel supply means when the flame current is lower than the set value. CONSTITUTION:When a specified time has passed after starting combustion and the combustion is stabilized, detection is started. The flame current If that flows to a burner 1 from a flame rod 2 is detected by a flame current detection circuit 11. Here, in a state wherein the supplied air volume is fixed, a state judgement section 12 increases the oscillation frequency of a pump 6 a little. In the pump 6 the oscillation frequency is roughly proportional to the fuel supply volume, and if the frequency is increased a little, the fuel supply volume increases and the primary air ratio mubecomes smaller. Here, if the flame current If increases mu>mu0, is judged, and if If decreases, a state judgement section 12 judges that mu<mu0, and it sends signal to a comparison section 13. If the comparison section 13 Judges that mu<mu0 by the state judgement section 12, Ifz is adopted as a set value Ifs and Ifs=Ifz. When later the flame current If<Ifs, the combustion is judged abnormal and a stopping section 16 stops the pump 6 and shuts down the burner.
