燃气发电机组顾名思义就是烧燃气的发电机组，分为内燃发电机组和燃气轮发电机组，他们都是以燃气作为燃料。下面来介绍一下燃气发电机组的燃烧方式以及注意事项吧。

As the name implies, gas-fired generator sets are gas-fired generator sets, which are divided into internal combustion generator sets and gas turbine generator sets. They all use gas as fuel. Let's introduce the combustion mode and precautions of the gas generator set.

燃烧方式：

Combustion mode:

1、燃气发电机组的稀薄燃烧，混合气体中的燃气含量低，燃气燃料与空气之比可达1：25以上的发动机。这种发动机不足就是排放残留过多的氧，损失了动力，但优点是缸体内燃料的燃烧是充分的，并且氮氧化物排放量降低了。

1. The lean combustion of the gas-fired generator set, the gas content in the mixed gas is low, and the ratio of gas fuel to air can reach more than 1:25. The disadvantage of this engine is that it emits too much residual oxygen and loses power, but the advantage is that the combustion of fuel in the cylinder is sufficient and the emission of nitrogen oxides is reduced.

2、燃气发电机组的燃烧方式按化学计量燃烧：指可燃混合气中理论上可完全燃烧的实际含有的燃气量与空气量之比，是表示可燃混合气中燃料量与空气量配合比例的一个参数。

2. The combustion mode of the gas-fired generator set is stoichiometric combustion: it refers to the ratio of the actual gas quantity and air quantity in the combustible mixture that can be completely combusted in theory, and is a parameter indicating the proportion of the fuel quantity and air quantity in the combustible mixture.

当量比大于1，表示可燃混合气中所含实际空气量少于所须的理论空气量，即空气量不足，燃烧效率随燃油当量比增加而下降；

If the equivalence ratio is greater than 1, it means that the actual air quantity contained in the fuel mixture is less than the required theoretical air quantity, that is, the air quantity is insufficient, and the combustion efficiency decreases with the increase of the fuel equivalence ratio;

反之，当量比小于1，则表示可燃混合气中所含实际空气量超过所需的理论空气量，即空气量过剩。当量比实际上就是过量空气系数的倒数。这种燃烧氮氧化物的排量高，温度也很高，高的时候可达到700摄氏度。

On the contrary, if the equivalence ratio is less than 1, it means that the actual air quantity contained in the combustible mixture exceeds the required theoretical air quantity, that is, the air quantity is excessive. The equivalent ratio is actually the reciprocal of the excess air coefficient. This kind of combustion of nitrogen oxides has high emission and high temperature, which can reach 700 degrees Celsius.

3、燃气发电机组的富燃烧，所谓富燃烧就是燃料多，氧气相对说少一些，但是他的动力足，但由于在缸体内会燃烧不充分，会通过烟管排到外面来。优点是动力十足，燃料温度低，不足之处是一氧化碳排量多，燃料消耗高。

3. The rich combustion of the gas-fired generator set means that there is more fuel and less oxygen, but its power is sufficient. However, due to insufficient combustion in the cylinder, it will be discharged to the outside through the smoke pipe. The advantages are full power and low fuel temperature. The disadvantages are high carbon monoxide emission and high fuel consumption.

注意事项：

matters needing attention:

5、机房内应符合消防要求，配备灭火器等消防器械；

5. The machine room shall meet the fire-fighting requirements and be equipped with fire extinguishers and other fire-fighting equipment;

6、机房内安装可燃气体报警装置，可燃气体泄露时能及时发现。

6. A combustible gas alarm device is installed in the machine room to detect the leakage of combustible gas in time.
