燃氣發(fā)電機組的燃氣方式是怎樣的，對于具體的燃氣方式，作為燃氣發(fā)電機廠家，讓小編帶大家共同了解一下。

What is the gas method for gas generators? As a gas generator manufacturer, let me take you to understand the specific gas method together.

燃氣發(fā)電機組的稀薄燃燒，混合氣體中的燃氣含量低，燃氣燃料與空氣之比可達1：25以上的發(fā)動機。這種發(fā)動機不足就是排放殘留過多的氧，損失了動力，但優(yōu)點是缸體內燃料的燃燒是充分的，并且氮氧化物排放量降低了。

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 deficiency of this type of engine is that it emits too much residual oxygen, losing power. However, the advantage is that the combustion of fuel in the cylinder is sufficient, and the emission of nitrogen oxides is reduced.

燃氣發(fā)電機組的燃燒方式按化學計量燃燒：指可燃混合氣中理論上可完全燃燒的實際含有的燃氣量與空氣量之比，是表示可燃混合氣中燃料量與空氣量配合比例的一個參數(shù)。

The combustion method of gas generator sets is stoichiometric combustion: it refers to the ratio of the actual amount of gas contained in the combustible mixture that can be completely combusted theoretically to the amount of air. It is a parameter that represents the proportion of fuel and air in the combustible mixture.

當量比大于1，表示可燃混合氣中所含實際空氣量少于所須的理論空氣量，即空氣量不足，燃燒效率隨燃油當量比增加而下降；

If the equivalence ratio is greater than 1, it indicates that the actual air content in the combustible mixture is less than the required theoretical air volume, that is, the air volume is insufficient, and the combustion efficiency decreases as the fuel equivalence ratio increases;

反之，當量比小于1，則表示可燃混合氣中所含實際空氣量超過所需的理論空氣量，即空氣量過剩。當量比實際上就是過量空氣系數(shù)的倒數(shù)。這種燃燒氮氧化物的排量高，溫度也很高，高的時候可達到700攝氏度。

On the contrary, if the equivalence ratio is less than 1, it indicates that the actual air content in the combustible mixture exceeds the required theoretical air volume, that is, excess air volume. 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 up to 700 degrees Celsius at high temperatures.

燃氣發(fā)電機組的富燃燒，所謂富燃燒就是燃料多，氧氣相對說少一些，但是他的動力足，但由于在缸體內會燃燒不充分，會通過煙管排到外面來。優(yōu)點是動力十足，燃料溫度低，不足之處是一氧化碳排量多，燃料消耗高。

The rich combustion of gas generator sets refers to having more fuel and relatively less oxygen, but it has sufficient power. However, due to insufficient combustion in the cylinder, it will be discharged outside through smoke pipes. The advantages are full power, low fuel temperature, but the disadvantages are high carbon monoxide emissions and high fuel consumption.
