Abstract
A safety device for protecting a burner of a coal gasification plant against solid blockage. Solid blockage may occur in a burner of a coal gasification plant fed with a mixture of coal particles and fluid. In order to protect the burner against solid blockage a safety device is proposed which is arranged in the supply line to the burner. By means of this safety device relatively large pieces of solid material, which might cause blockage of the burner, can be eliminated from the mixture of coal particles and fluid supplied to the burner.
