A new kind of burner, bluff-body with cavity burner, which is based on the bluff-body burner is developed in this paper. The three dimension mean velocity and turbulent characteristics have been measured in the burner`s recirculation zone by using three dimension laser dynamics analysis. For a low rank anthracite, combustion test shows this burner is better than bluff-body in ignition and flame stability. 50 MW(220T/H) boiler operation show that the temperature in the flame zone is high, combustion is very stable and the efficiency is increased when this burner is used.
