燃氣發(fā)電機組一般分為汽輪機發(fā)電和內燃機發(fā)電，一般燃氣發(fā)電機組采用往復活塞式內燃機效率，國外顏巴赫、瓦克夏等品牌發(fā)電效率一般在38-40%，國內濟柴品牌做的，一般在35-38%。

The gas generator set is generally divided into steam turbine power generation and internal combustion engine power generation. Generally, the reciprocating piston internal combustion engine is used for the gas generator set with the highest efficiency. The power generation efficiency of foreign brands such as Yanbach and Waksha is generally 38-40%, while the domestic brands of Jichai do the best, generally 35-38%.

采用燃氣輪機發(fā)電，一般一次燃燒帶動燃氣輪機發(fā)電的效率為28-30%；二次蒸汽發(fā)電效率在15-20%。

Gas turbine is used for power generation. Generally, the efficiency of gas turbine power generation driven by primary combustion is 28-30%; The efficiency of secondary steam power generation is 15-20%.

由此可見，燃氣發(fā)電機組發(fā)電效率通常在30%-40%之間，常見的機型一般可以達到35%。燃氣內燃機的優(yōu)點是發(fā)電效率比較高，其次是設備集成度高，安裝快捷。對于氣體中的粉塵要求不高，基本不需要水，設備的單位千瓦造價也比較低。

It can be seen that the power generation efficiency of gas generating units is usually between 30% and 40%, and the common models can generally reach 35%. The advantages of gas internal combustion engine are high power generation efficiency, high equipment integration and fast installation. The requirement for dust in the gas is not high, and water is basically not needed, and the unit kilowatt cost of the equipment is also relatively low.、

燃氣發(fā)電機組常見的額定發(fā)電效率，如果是進口燃氣發(fā)電機組一般為38%—42%之間，國產機組實際發(fā)電效率為30%—35%之間。

The common rated power generation efficiency of gas generator sets is between 38% and 42% for imported gas generator sets, and between 30% and 35% for domestic units.

除了需要了解燃氣發(fā)電機組的耗氣量，還需要確定如下幾個問題：

In addition to knowing the gas consumption of the gas generator unit, the following issues need to be determined:

① 每度電的能量等同于3.6MJ。

① The energy per kilowatt-hour is equivalent to 3.6MJ.

② 使用的天然氣的熱值為多少，一般為8300大卡—8500大卡之間（折合為34.7—35.6MJ），但是近年來燃氣公司都在使用技術手段降低熱值，天然氣熱值擬定為35MJ每立方。

② The calorific value of natural gas used is generally between 8300 kcal and 8500 kcal (equivalent to 34.7-35.6 MJ), but in recent years, gas companies have been using technical means to reduce the calorific value, and the calorific value of natural gas is proposed to be 35 MJ per cubic meter.

③ 確定發(fā)電機組發(fā)電效率（當發(fā)電功率為700KW時），擬定為40%

③ Determine the generating efficiency of the generator unit (when the generating power is 700KW), which is proposed to be 40%

計算如下：

The calculation is as follows:

700÷（35÷3.6×40%）≈180m

700÷（35÷3.6 × 40%）≈180m
