Embodiment Construction

[0011]Therefore, it has been the object to find a solution for extending the service life of the burner, which rather does not intervene in the construction of the burner and can be carried out economically.

[0012]The solution of the object according to the invention substantially can be derived from the characterizing features of claim 1 in conjunction with the features of the generic part. Further advantageous aspects of the invention can be taken from the sub-claims. This invention also relates to a process for the partial oxidation of liquid, carbonaceous fuel with steam and an oxygen-containing gas, in which the burner according to the invention is used.

[0013]This object is solved in that the parts of the outlet orifice directed towards the combustion chamber are wholly or partly provided with a coating or with a diffusion layer for protection against thermal load and / or corrosion.

[0014]This inventive solution of the object was induced by the proven practice in the construction ...

Abstract

A burner for the partial oxidation of liquid, carbonaceous fuel with steam and an oxygen-containing gas a well as the process in which this burner is used, wherein the parts of the outlet orifice of the burner directed towards the combustion chamber are wholly or partly provided with a coating or with a diffusion layer for protection against thermal load and/or corrosion.

Description

FIELD OF THE INVENTION[0001]This invention relates to a burner for the partial oxidation of liquid, carbonaceous fuel with steam and an oxygen-containing gas, and to the process for producing synthesis gas by partial oxidation of said fuels, in which the burner according to the invention is used.PRIOR ART[0002]A known process for the partial oxidation of liquid, carbonaceous feedstocks for the production of synthesis gas for example is the Lurgi process as described in Ullmann's Encyclopedia of Industrial Chemistry, 6th Edition, Volume 15, Chapt. 3.2.2.[0003]In such processes, the hydrocarbonaceous feedstock stream, e.g. heavy oil, together with the oxygen-containing oxidizing agent, e.g. air enriched with oxygen, and possibly a moderator (mostly steam or carbon dioxide) is converted into a synthesis gas chiefly consisting of carbon monoxide and hydrogen in a reactor space (combustion chamber) at temperatures of 1200 to 1500° C. and high pressures, between 30 and 75 bar.[0004]The re...
