More Information
Summary:The invention relates to a fuel nozzle applied to the field of combustion, in particular to a direct-flow fuel nozzle capable of effectively preventing carbon deposit. On account of the characteristic that a direct-flow nozzle is easy in carbon deposit and according to the requirement of a combustion device on carbon deposit prevention for the nozzle, the scheme of connecting a traditional fuel nozzle with a sleeve is proposed, and transfer of heat flow in the fuel nozzle is decreased, so that the direct-flow fuel nozzle is free of carbon deposit in long-time operation. The direct-flow fuel nozzle capable of preventing carbon deposit is used on a certain scramjet engine, achieves fine effects, and can be applied to combustion devices such as an aircraft engine, an internal-combustion engine and the like.
