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高，國外顏巴赫、瓦克夏等品牌發(fā)電效率一般在38-40%，國內華全品牌做的好，一般在35-38%。

　　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 high efficiency. Foreign brands such as Yanbach and Wakxia generally have a power generation efficiency of 38-40%, while domestic brands such as Huaquan do well, generally 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 gas turbines for power generation, the efficiency of a single combustion 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。

　　From this, it can be seen that the power generation efficiency of gas-fired generators is usually between 30% and 40%, and common models can generally reach 35%. The advantages of gas internal combustion engines are relatively high power generation efficiency, followed by high equipment integration and quick installation. The requirements for dust in gas are 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 generators, the following issues need to be determined:

　　① 每度電的能量等同于3.6MJ。

　?、?The energy per kilowatt hour is equivalent to 3.6 MJ.

　?、?使用的燃氣的熱值為多少，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，燃氣熱值擬定為35MJ每立方。

　?、?What is the calorific value of the gas used, usually between 8300 kcal and 8500 kcal (equivalent to 34.7-35.6MJ), but in recent years, gas companies have been using technological means to reduce the calorific value, with a proposed calorific value of 35MJ 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 power generation efficiency of the generator set (when the power generation is 700KW), and set it at 40%

　　計算如下：

　　The calculation is as follows:

　　700÷（35÷3.6×40%）≈180m

　　700÷（35÷3.6×40%）≈180m

　　燃氣發(fā)電機組一小時耗材多少

　　How much consumables do gas generators consume per hour

　　燃氣發(fā)電機組的耗材有哪些呢？燃氣，機油和冷卻液，那么燃氣發(fā)電機組對付這些耗材的要求有什么呢？

　　What are the consumables for gas generator sets? What are the requirements for gas generators to deal with these consumables, such as gas, oil, and coolant?

　　1、燃氣發(fā)電機組利用燃氣要求：自然氣的燃氣發(fā)動機的燃料，也可以利用相干的氣體，液化煤油氣，甲烷等可燃性氣體。應該被利用的氣體舉行脫水，沒有游離水，原油和輕質油，低的熱值不小于31.4mj/m3，總硫含量不凌駕480mg/m3，硫化氫的含量不比為20mg/m3。進一步的自然氣壓力在0.08-0.30MAP的范疇內。

　　1. Gas generator sets require the use of natural gas as fuel for gas engines, as well as combustible gases such as liquefied kerosene, methane, etc. The gas that should be utilized should undergo dehydration without free water, crude oil, and light oil. The low calorific value should not be less than 31.4mj/m3, the total sulfur content should not exceed 480mg/m3, and the hydrogen sulfide content should not exceed 20mg/m3. Further natural gas pressure is within the range of 0.08-0.30MAP.

　　2、機油：燃氣發(fā)電機組油用于潤滑移動部件，這些活動部件的冷卻熱，撤除雜質，并防備生銹的結果。其質量是好照舊壞，除了在燃氣發(fā)動機的性能和利用壽命的外界的影響，在肯定水平上利用，在油田時期。為此目標，應憑據(jù)對自然氣發(fā)動機驅動型發(fā)電機組，選擇得當?shù)睦们闆r溫度的油。只要有燃氣發(fā)電機組大概，利用自然氣發(fā)動機，燃氣發(fā)動機油15W40CD或15W40CC等。

　　2. Engine oil: Gas generator set oil is used to lubricate moving parts, cool them, remove impurities, and prevent rusting. Whether its quality is good or bad, apart from external influences on the performance and service life of gas engines, it is utilized at a certain level during the oil field period. For this goal, it is necessary to select appropriate oil that utilizes the temperature of the natural gas engine driven generator set. As long as there is a gas generator set, use natural gas engines, gas engine oil 15W40CD or 15W40CC, etc.

　　3、燃氣發(fā)電機組利用的冷卻液：用于冷卻燃氣發(fā)電機組冷卻液通常利用潔凈的凈水，雨水，或澄凈水直接冷卻體系，是得當?shù)模斎細獍l(fā)電機組在0度以下的情況條件下利用時，應防備冷卻液結冰，導致開裂部門。憑據(jù)配備開始添補前用得當?shù)姆纼鲆夯蛩谋c的溫度，但立刻停后水。

　　3. Cooling fluid used for gas generator sets: The cooling fluid used for gas generator sets is usually cooled directly using clean water, rainwater, or purified water, which is appropriate. When gas generator sets are used under conditions below 0 degrees, precautions should be taken to prevent the cooling fluid from freezing and causing cracking in the area. Use appropriate antifreeze or water to measure the freezing point temperature before starting to replenish, but immediately stop the water afterwards.
