瓦斯發(fā)電機(jī)組的燃?xì)庀牧坑?jì)算需結(jié)合熱效率、天然氣熱值及發(fā)電量綜合確定，具體公式如下：

　　The calculation of gas consumption for gas generator sets needs to be determined comprehensively based on thermal efficiency, natural gas calorific value, and power generation. The specific formula is as follows:

　　一、核心計(jì)算公式

　　1、 Core calculation formula

　　燃?xì)庀牧浚⒎矫?小時(shí)）= 發(fā)電量（度） / （天然氣熱值（MJ/立方米）× 發(fā)電效率（%）/ 3600）

　　Gas consumption (cubic meters/hour)=power generation (kWh)/(natural gas calorific value (MJ/cubic meter) x power generation efficiency (%)/3600)

　　其中：

　　among which

　　天然氣熱值 ：約8300-8500大卡/立方米（34.7-35.6MJ/立方米）

　　Natural gas calorific value: approximately 8300-8500 kcal/m3 (34.7-35.6MJ/m3)

　　發(fā)電效率 ：進(jìn)口機(jī)組通常為38%-42%，國(guó)產(chǎn)機(jī)組為30%-35%

　　Power generation efficiency: Imported units are usually 38% -42%, while domestic units are 30% -35%

　　1度電=3.6MJ

　　1 kWh of electricity=3.6MJ

　　二、計(jì)算示例

　　2、 Calculation Example

　　以1000千瓦燃?xì)獍l(fā)電機(jī)為例：

　　Taking a 1000 kW gas generator as an example:

　　基礎(chǔ)數(shù)據(jù)

　　Basic Data

　　發(fā)電量：1000度/小時(shí)

　　Power generation: 1000 kWh

　　天然氣熱值：8500大卡/立方米（35.6MJ/立方米）

　　Natural gas calorific value: 8500 kcal/m3 (35.6MJ/m3)

　　發(fā)電效率：40%

　　Power generation efficiency: 40%

　　代入公式

　　substitute into the formula

　　$$

　　$$

　　\text{燃?xì)庀牧縸 = \frac{1000}{(35.6 \times 0.4 / 3600)} \approx 264.6 \text{立方米/小時(shí)}

　　\Text {Gas Consumption}=\ frac {1000} {(35.6 \ times 0.4/3600)} \ estimate 264.6 \ text {cubic meters/hour}

　　$$

　　$$

　　即每小時(shí)需約264.6立方米天然氣。

　　Approximately 264.6 cubic meters of natural gas are required per hour.

　　三、注意事項(xiàng)

　　3、 Precautions

　　效率差異 ：實(shí)際消耗量受機(jī)組熱效率影響顯著，效率越高，燃?xì)饫寐试礁摺?/p>

　　Efficiency difference: The actual consumption is significantly affected by the thermal efficiency of the unit, and the higher the efficiency, the higher the gas utilization rate.

　　熱值波動(dòng) ：天然氣熱值可能因品質(zhì)不同略有變化，建議以實(shí)際測(cè)量值為準(zhǔn)。

　　Fluctuations in calorific value: The calorific value of natural gas may vary slightly due to different qualities, and it is recommended to use the actual measured value as the standard.

　　單位換算 ：計(jì)算中需統(tǒng)一單位（如熱值用MJ/立方米，效率用%），避免混淆。

　　Unit conversion: Unified units should be used in calculations (such as MJ/cubic meter for calorific value and% for efficiency) to avoid confusion.

　　通過上述公式及示例，可準(zhǔn)確估算不同功率燃?xì)獍l(fā)電機(jī)的燃?xì)庀牧俊?/p>

　　By using the above formula and examples, the gas consumption of different power gas generators can be accurately estimated.
