Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] see Figure 1-5, the embodiment of the present invention provides a technical solution: a fuel metering and mixing device for a gas generator set, including a heater 1 and a mixing chamber 2, the heater 1 heats the incoming air, and can quickly pre-heat the gas. heat, so that the gas can quickly heat up when burning, the combustion effect is better, and the combustion utilization rate of the gas is increased. The top of the mixing chamber 2 is fixedly c...

The invention discloses a gas generator set fuel metering and mixing device and a control method thereof, and relates to the technical field of fuel mixing. The gas generator set fuel metering and mixing device comprises a heater and a mixing cavity, wherein an air pipeline communicates with the left side of the mixing cavity; one end of a heating wire of the heater penetrates through the surfaceof the air pipeline and extends to an inner cavity of the air pipeline; and the inner cavity of the heater is fixedly connected with the surface of the air pipeline. According to the gas generator setfuel metering and mixing device and the control method thereof, when gas and air are mixed, the air is diverted so as to be mixed with the gas through three steps; and when the gas is atomized and then introduced into the mixing cavity, hot air conveyed through a first communication pipeline is used for assisting, the hot air is prevented from flowing backwards into an air inlet pipeline, and theair flows convectively with the hot air blown out of an air outlet cavity when passing through mixing frames, so that the mixing is more thorough, the mixing effect is good, hot air backflow is prevented, and the combustion efficiency of fuel gas is improved.
Description
technical field [0001] The invention relates to the technical field of fuel mixing, in particular to a fuel metering and mixing device for a gas generating set and a control method thereof. Background technique [0002] Gas generator set is a new type of generator set developed to meet the world's environmental protection requirements and the new market environment. Natural gas generator sets are mainly divided into two types, one is a combined cycle gas turbine, and the other is a gas internal combustion engine. The power of the gas turbine is relatively large, and it is mainly used in large , medium-sized power stations, the power of gas internal combustion engines is relatively small, mainly used in small distributed power stations, it is a new type of green power to replace oil and coal-fired units, gas generators make full use of various natural gas or harmful gases as fuel, and turn waste into It has the advantages of safe and convenient operation, high cost-effectivenes...
