The main component of gas is alkanes, with methane accounting for the vast majority and a few being ethane, propane, and butane. In addition, there are hydrogen sulfide, carbon dioxide, nitrogen, and water gas, as well as certain inert gases such as helium, argon, and so on. Gas is a popular term for natural gas, which can be roughly divided into three categories: liquefied petroleum gas, natural gas, and coal gas. These three categories exist in all aspects of people's lives and play a very important role.

瓦斯發電機組按照瓦斯氣體的濃度可分為低濃度瓦斯發電機組和高濃度瓦斯發電機組，低濃度瓦斯發電機組是指瓦斯氣體的濃度低于25%，而高濃度瓦斯發電機組是指瓦斯氣體濃度高于25%的發電機組，相對于低瓦斯發電機組而言，高濃度瓦斯發電機組較好掌控，比較容易使用。

Gas generator sets can be divided into low concentration gas generator sets and high concentration gas generator sets based on the concentration of gas. Low concentration gas generator sets refer to generator sets with gas concentrations below 25%, while high concentration gas generator sets refer to generator sets with gas concentrations above 25%. Compared to low concentration gas generator sets, high concentration gas generator sets are better controlled and easier to use.

根據以上數據顯示，我國國產瓦斯發電機組之所以沒有達到設計的預想發電量，影響的原因具體可氛圍也以下幾點：

According to the above data, the specific reasons for the failure of domestically produced gas generator units in China to achieve the expected power generation capacity can be summarized as follows:

（1）我國瓦斯發電機組中蘊含的瓦斯成分可能含有水分，從而造成瓦斯濃度不夠穩定，進入到內部的瓦斯氣體忽高忽低，氣體中含有二氧化碳等其他阻礙氣體，致使存在于燃氣內燃機中的燃料不能得到充分地燃燒，部分熱量損失，大大降低了瓦斯發電機組單位瓦斯的發電功率。

(1) The gas components contained in gas generator sets in China may contain moisture, resulting in unstable gas concentration. The gas entering the interior fluctuates from high to low, and the gas contains other obstructive gases such as carbon dioxide. This results in insufficient combustion of the fuel present in gas internal combustion engines, resulting in partial heat loss and greatly reducing the power generation per unit of gas in gas generator sets.

（2）我姑國產瓦斯尾氣排放氣體溫度過高，且缺乏余熱回收系統，致使不少燃料的熱能資源遭到浪費。

(2) My aunt's domestic gas exhaust emissions have a high temperature and a lack of waste heat recovery system, resulting in the waste of many fuel thermal energy resources.

（3）海拔較高的地區瓦斯機組相對較低，加之風沙等惡劣環境的阻礙，瓦斯機組的相關配件之間產生了一定的摩擦力，大大降低了機組的機械效率，從而也影響了瓦斯發電機組的輸出功率。

(3) In areas with high altitude, the gas generator set is relatively low. In addition to the obstacles of harsh environments such as wind and sand, a certain friction force is generated between the relevant accessories of the gas generator set, which greatly reduces the mechanical efficiency of the unit, thus affecting the output power of the gas generator set.

（4）瓦斯發電機組的各個部件是否處在正常的水平之下，安裝是否按照嚴格的組裝標準等方面都會對瓦斯發電機組各個部件的運動慣性產生一定的影響，從而制約瓦斯發電機組的發電狀態。

(4) Whether the various components of a gas generator set are at a normal level and installed in accordance with strict assembly standards will have a certain impact on the motion inertia of each component of the gas generator set, thereby restricting the power generation status of the gas generator set.

（5）冷卻系統的選用會影響發電機組冷卻時減少多少熱量，在一定程度上瓦斯發電機組正常運行狀態下，適當減少冷卻介質可有效提高瓦斯發電機組的工作效率。

(5) The selection of cooling system will affect how much heat is reduced during the cooling of the generator set. To a certain extent, reducing the cooling medium appropriately can effectively improve the working efficiency of the gas generator set under normal operating conditions.
