燃氣發(fā)電機組顧名思義就是燒燃氣的發(fā)電機組，分為內燃發(fā)電機組和燃氣輪發(fā)電機組，他們都是以燃氣作為燃料。下面來(lái)介紹一下燃氣發(fā)電機組的燃燒方式以及注意事項吧。

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.

燃燒方式：

Combustion mode:

1、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(dòng)機。這種發(fā)動(dòng)機不足就是排放殘留過(guò)多的氧，損失了動(dòng)力，但優(yōu)點(diǎn)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。

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、燃氣發(fā)電機組的燃燒方式按化學(xué)計量燃燒：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(gè)參數。

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.

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

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(shuō)少一些，但是他的動(dòng)力足，但由于在缸體內會(huì )燃燒不充分，會(huì )通過(guò)煙管排到外面來(lái)。優(yōu)點(diǎn)是動(dòng)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。

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.
