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(fā)電機(jī)組按照瓦斯氣體的濃度可分為低濃度瓦斯發(fā)電機(jī)組和高濃度瓦斯發(fā)電機(jī)組，低濃度瓦斯發(fā)電機(jī)組是指瓦斯氣體的濃度低于25%，而高濃度瓦斯發(fā)電機(jī)組是指瓦斯氣體濃度高于25%的發(fā)電機(jī)組，相對于低瓦斯發(fā)電機(jī)組而言，高濃度瓦斯發(fā)電機(jī)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(jù)以上數(shù)據(jù)顯示，我國國產(chǎn)瓦斯發(fā)電機(jī)組之所以沒有達(dá)到設(shè)計(jì)的預(yù)想發(fā)電量，影響的原因具體可氛圍也以下幾點(diǎn)：

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(fā)電機(jī)組中蘊(yùn)含的瓦斯成分可能含有水分，從而造成瓦斯?jié)舛炔粔蚍€(wěn)定，進(jìn)入到內(nèi)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?xì)鈨?nèi)燃機(jī)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(fā)電機(jī)組單位瓦斯的發(fā)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(chǎn)瓦斯尾氣排放氣體溫度過高，且缺乏余熱回收系統(tǒng)，致使不少燃料的熱能資源遭到浪費(fèi)。

(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(qū)瓦斯機(jī)組相對較低，加之風(fēng)沙等惡劣環(huán)境的阻礙，瓦斯機(jī)組的相關(guān)配件之間產(chǎn)生了一定的摩擦力，大大降低了機(jī)組的機(jī)械效率，從而也影響了瓦斯發(fā)電機(jī)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(fā)電機(jī)組的各個(gè)部件是否處在正常的水平之下，安裝是否按照嚴(yán)格的組裝標(biāo)準(zhǔn)等方面都會對瓦斯發(fā)電機(jī)組各個(gè)部件的運(yùn)動慣性產(chǎn)生一定的影響，從而制約瓦斯發(fā)電機(jī)組的發(fā)電狀態(tài)。

(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(tǒng)的選用會影響發(fā)電機(jī)組冷卻時(shí)減少多少熱量，在一定程度上瓦斯發(fā)電機(jī)組正常運(yùn)行狀態(tài)下，適當(dāng)減少冷卻介質(zhì)可有效提高瓦斯發(fā)電機(jī)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.
