Problems solved by technology

On the one hand, the high temperature causes the fuel inside the flow channel to decompose, resulting in coking and carbon deposits, which block the fine swirl grooves on the swirl body; on the other hand, on the outer surface of the fuel injection device, the incompletely burned fuel will Generate carbon deposits and block fuel injectors

Abstract

The invention discloses an anti-carbon fuel injection device, which comprises: a fuel injection mechanism and an oxidant injection mechanism; the fuel injection mechanism includes a fuel pipe and a fuel nozzle assembly; The injection section installed on the side; the fuel injection nozzle assembly is installed at the end of the injection section away from the fuel inlet section; the fuel that flows through the oil inlet section and the high temperature end in turn and is injected by the fuel injection nozzle assembly is injected by the oxidizer injection mechanism The oxidant and high-temperature flue gas are mixed in the mixing channel of the mixing tube and then flow to the combustion chamber; the injection section extends into the mixing channel; the side wall of the injection section is provided with a channel for circulating cooling fluid. The present invention performs heat exchange between the cooling fluid and the oil pipe, and further realizes the cooling of the fuel oil in the fuel passage of the oil pipe to reduce the generation of carbon deposits, thereby reducing the carbon deposits in the fuel passages, improving the quality of fuel injection, and preventing the fuel nozzle assembly from being deposited by carbon The blockage will affect the working performance of the engine.

Description

technical field [0001] The invention relates to the technical field of fuel injection devices for engines, in particular to a carbon deposition prevention fuel injection device. Background technique [0002] Fuel injection devices are widely used in internal combustion engines, gas turbines, Stirling engines and oil-fired boilers. They are the core components of such thermal energy equipment and directly affect the performance and efficiency of the equipment. If it is damaged, it can lead to shutdown in serious cases. . In continuous combustion equipment such as boilers, gas turbines and Stirling engines, in order to improve the spray quality, pressure atomized fuel injection devices, also known as centrifugal fuel injection devices, are generally used. This type of injection device has an independent swirl fluid inside, and the fuel will rotate when passing through the small swirl groove outside the swirl fluid to improve the atomization quality. [0003] In Stirling engi...
