きボイラの燃焼制御装置。[Scope of Claim for Utility Model Registration] In a combustion control system for a gas-fired boiler in which a temperature sensor in the tube of the upper header and a heat demand detection device are installed in the boiler body, and these signals are taken into the combustion control system to perform combustion control. After the combustion is stopped by the heat demand stop signal, the transmission time of the heat demand signal is calculated from the signal from the heat demand detection device and the measured value from the pipe temperature sensor of the upper header, and the actual heat demand time elapses. A combustion control device for a gas-fired boiler, characterized in that a pre-purge operation is performed before or after a heat request signal is transmitted so as to start combustion back and forth.
