However, the integrated pulverized coal burner is directly installed on the gasification furnace after leaving the factory, and then the integrated pulverized coal burner is tested on site, however, because the flame sprayed by the integrated pulverized coal burner is located in the hearth, whether the burner is on point, the length, color and combustion state of the flame cannot be effectively observed, and then the stability, strength and rigidity of the flame cannot be determined, and when the back pressure increases, the degree of the flame compression and the respective attenuation degrees of the fuel gas and the ignition air flow cannot be monitored. Thus, repeated testing is required for many times, and the flow ratio of the fuel gas and the ignition air is continuously changed until stable flame can be detected by fire detection. In the stage of ignition start-up, the working condition in the gasifier is extremely unstable and changes in real time, so that the flow regulation is difficult to match the real-time working condition, and the conditions that the mixture ratio of fuel and air is not proper and the ignition is not performed frequently occur in the debugging and normal operation processes, or the flow attenuation of the fuel and the air is inconsistent along with the rise of pressure after the ignition so that the flame drifts or even extinguishes and the like often occur, so that the time and the fuel cost are consumed.
