Abstract
The invention relates to burners for the gasification of pulverized coal--injected in a dense phase--with steam and oxygen, and it can be employed for coal gasification in the chemical industry. Objects of the present invention are to increase the reliability in operation of the burner and to improve the quality of the gas obtained from the gasification process. The burner should be designed in such a way that a reliable operation is attained under the conditions of the gasification process (e. g. high pressures and temperatures within the gasifier). The design of the pulverized-coal feeding device, the water-cooled jacket and the swirl chamber according to the invention are described in detail.
