Gas generator sets are generally divided into steam turbine power generation and internal combustion engine power generation. Generally, gas generator sets use reciprocating piston internal combustion engines with the highest efficiency. Foreign brands such as Yanbach and Waksha generally have power generation efficiency of 38-40%, while domestic brands such as Jichai do the best, usually at 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%。

Using a gas turbine for power generation, the efficiency of driving the gas turbine for power generation is generally 28% -30%; The efficiency of secondary steam power generation is between 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(nèi)燃機的優(yōu)點是發(fā)電效率比較高，其次是設(shè)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(shè)備的單位千瓦造價也比較低。

It can be seen that the power generation efficiency of gas generator sets is usually between 30% -40%, and common models can generally reach 35%. The advantage of gas internal combustion engines is their high power generation efficiency, followed by high equipment integration and fast installation. The requirement for dust in the gas is not high, and water is basically not needed. The unit cost of equipment per kilowatt 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(chǎn)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 generally between 38% and 42% for imported gas generator sets, while the actual power generation efficiency of domestic units is between 30% and 35%.

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 understanding the gas consumption of gas generator units, it is also necessary to determine the following issues:

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(shù)手段降低熱值，天然氣熱值擬定為35MJ每立方。

② What is the calorific value of natural gas used, usually between 8300 kcal and 8500 kcal (equivalent to 34.7-35.6 MJ), but in recent years, gas companies have been using technological means to reduce the calorific value of natural gas, with a proposed calorific value of 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

③ Determine the power generation efficiency of the generator set (when the power generation is 700KW), and propose to

計算如下：

The calculation is as follows:
