When a gas generator set burns, what is the specific combustion method? As a gas generator manufacturer, let me take you to understand the combustion methods of gas generator sets together 1. The rich combustion of gas generator sets refers to the fact that there is more fuel and relatively less oxygen, but it has sufficient power. However, due to insufficient combustion in the cylinder, it will be discharged to the outside through smoke pipes. The advantages are full power, low fuel temperature, and the disadvantages are high carbon monoxide emissions and high fuel consumption.

The lean combustion of gas generator sets results in low gas content in the mixed gas, and the ratio of gas fuel to air can reach 1:25 or higher in engines. The disadvantage of this type of engine is that it emits excessive residual oxygen and loses power. However, the advantage is that the combustion of fuel in the cylinder is sufficient, and the emission of nitrogen oxides is reduced.

燃?xì)獍l(fā)電機(jī)組的燃燒方式按化學(xué)計(jì)量燃燒：指可燃混合氣中理論上可完全燃燒的實(shí)際含有的燃?xì)饬颗c空氣量之比，是表示可燃混合氣中燃料量與空氣量配合比例的一個(gè)參數(shù)。當(dāng)量比大于1，表示可燃混合氣中所含實(shí)際空氣量少于所一定的理論空氣量，即空氣量不足，燃燒效率隨燃油當(dāng)量比增加而下降。

The combustion method of a gas generator set is stoichiometric combustion: it refers to the ratio of the actual amount of gas and air that can theoretically be completely combusted in the combustible mixture. It is a parameter that represents the proportion of fuel and air in the combustible mixture. If the equivalence ratio is greater than 1, it means that the actual amount of air in the combustible mixture is less than the theoretical amount of air, which means that the air volume is insufficient, and the combustion efficiency decreases as the fuel equivalence ratio increases.

反之，當(dāng)量比小于1，則表示可燃混合氣中所含實(shí)際空氣量超過(guò)所一定的理論空氣量，即空氣量過(guò)剩。當(dāng)量比實(shí)際上就是過(guò)量空氣系數(shù)的倒數(shù)。這種燃燒氮氧化物的排量高，溫度也很高，高的時(shí)候可達(dá)到700攝氏度。

On the contrary, if the equivalence ratio is less than 1, it means that the actual amount of air contained in the combustible mixture exceeds a certain theoretical amount of air, that is, excess air. The equivalence ratio is actually the reciprocal of the excess air coefficient. This type of combustion of nitrogen oxides has a high displacement and temperature, reaching 700 degrees Celsius at high temperatures.
