Research results of the cold aerodynamic flow characteristics of a bluff-body flame stabilizer mounted on the outlet of a tangential burner are reported.

After the burners were retrofitted, the goal of stable combustion is achieved and the minimum load without oil can lower to 65%.

The signal read out of the sensor is to be filtered, amplified, shaped and synthesized and then transformed into a digital pulse one, which is equivalent to the ignition time delay.
