Multi-point injection fuel gas generator using ethanol as fuel

Abstract

The invention provides a multi-point injection fuel gas generator using ethanol as a fuel. The generator comprises a diffuser, a fuel split atomizing device, a high-energy plasma ignition electric nozzle, a shell and a flame tube, the fuel split atomizing device and a head adapter section are fixed between a rear flange and a shell front flange, the high-energy plasma ignition electric nozzle 3 is fixed on the shell and a barrel body, an annular channel is arranged between the shell and the barrel body, a floating ring installation seat is arranged at the position, 20 mm -50 mm away from the head transferring section, of the barrel body, a clamping ring is arranged on the floating ring installation seat, a floating ring is fixed on the clamping ring, the end part of the high-energy plasma ignition power nozzle is fixed on the floating ring, and fuel supplementing holes and mixing holes are sequentially formed in an axial direction of the barrel body. The generator solves many problems existing in the existing fuel gas generator with the ethanol as the fuel, and has the advantages that the gas enthalpy value is high, the reliability of an ignition system is improved, the geometrical size under the large-volume flow is relatively small, weight is light, a cooling water system does not need to be arranged, running cost is low, combustion efficiency is high, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of gas generators using ethanol as fuel, in particular to a multi-point injection gas generator using ethanol as fuel. Background technique [0002] At present, the gas generators that use ethanol as fuel mainly include: (1) Single-tube combustion chamber gas generators. This type of gas generator has an upper limit on the volume flow rate. With the increase of the volume flow rate, the diameter of the single-tube flame tube continues to increase. , when the diameter of the flame tube reaches a certain level, the jet flow depth of the main combustion hole and the mixing hole is difficult to meet the needs of the combustion organization of the main combustion zone and the uniform mixing of the mixing zone, resulting in a decline in the performance of the generator; (2) the gas in the annular combustion chamber Generator, the gas generator disclosed in CN103697471A exists that with the increase of the volume f...
