瓦斯發電機組的燃氣消耗量計算需結合熱效率、天然氣熱值及發電量綜合確定，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、核心計算公式

　　1、 Core calculation formula

　　燃氣消耗量（立方米/小時）= 發電量（度） / （天然氣熱值（MJ/立方米）× 發電效率（%）/ 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)

　　發電效率 ：進口機組通常為38%-42%，國產機組為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、計算示例

　　2、 Calculation Example

　　以1000千瓦燃氣發電機為例：

　　Taking a 1000 kW gas generator as an example:

　　基礎數據

　　Basic Data

　　發電量：1000度/小時

　　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)

　　發電效率：40%

　　Power generation efficiency: 40%

　　代入公式

　　substitute into the formula

　　$$

　　$$

　　\text{燃氣消耗量} = \frac{1000}{(35.6 \times 0.4 / 3600)} \approx 264.6 \text{立方米/小時}

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

　　$$

　　$$

　　即每小時需約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

　　3、 Precautions

　　效率差異 ：實際消耗量受機組熱效率影響顯著，效率越高，燃氣利用率越高。

　　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 ：天然氣熱值可能因品質不同略有變化，建議以實際測量值為準。

　　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 ：計算中需統一單位（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，可準確估算不同功率燃氣發電機的燃氣消耗量。

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