Abstract
The gasification burner of this invention capable of maintaining a high combustion rate for a long period of time comprises a combustion chamber having a ceiling with a small hole in its center, a pre-mixing pipe fitted into the small hole and having a nozzle at its top, wherein the pre-mixing pipe and the combustion chamber are concentric, and the spread angle of the gas flow sprayed from the end of the pre-mixing pipe is between 10 and 40 degrees, so that the relationship between the bottom of the combustion chamber and the conical gas flow is regulated by keeping a good balance between the gasification rate of the powdered coke and the life of the combustion chamber.
