燃氣機組配置中與燃氣相關(guān)的問題，那么這一篇主要介紹環(huán)境條件對燃氣機組配置的影響！

　　In terms of gas related issues in gas turbine configuration, this article mainly introduces the impact of environmental conditions on gas turbine configuration!

　　環(huán)境條件主要是指地理條件因素，將影響機組的輸出功率及加裝配置的選擇。

　　Environmental conditions mainly refer to geographical factors that will affect the output power of the unit and the selection of installation configurations.

　　環(huán)境因素包括以下幾類：

　　Environmental factors include the following categories:

　　1、 海拔

　　1. Altitude

　　隨著海拔的升高，空氣將越來越稀薄，空氣的密度也將越來越小。相同體積的空氣中所含O2的質(zhì)量也越來越小，直到不能滿足發(fā)動機額定負載的需要。此時發(fā)動機將降載運行。

　　As the altitude increases, the air will become thinner and the density of the air will also decrease. The mass of O2 contained in the same volume of air also decreases until it cannot meet the requirements of the engine's rated load. At this point, the engine will run with reduced load.

　　同時對于高壓發(fā)電機組，應(yīng)檢查其發(fā)電機的電氣間隙是否符合規(guī)范要求。

　　At the same time, for high-voltage generator sets, the electrical clearance of their generators should be checked to ensure compliance with regulatory requirements.

　　2、 最高氣溫

　　2. Maximum temperature

　　溫度也是發(fā)動機降載的重要因素?？諝饷芏葘㈦S著氣溫升高而變小，到達某個溫度，發(fā)動機也將因為沒有足夠的O2而降載。

　　Temperature is also an important factor in engine load reduction. The air density will decrease as the temperature rises, and at a certain temperature, the engine will also be unloaded due to insufficient O2.

　　另一方面，環(huán)境溫度過高，將會導(dǎo)致發(fā)動機冷卻系統(tǒng)散熱能力下降而不能滿足發(fā)動機額定負載支持的散熱要求，降載運行。

　　On the other hand, if the ambient temperature is too high, it will lead to a decrease in the heat dissipation capacity of the engine cooling system, which cannot meet the heat dissipation requirements supported by the rated load of the engine, resulting in reduced load operation.

　　3、 最低氣溫

　　3. Minimum temperature

　　發(fā)動機的環(huán)境溫度，也不是越低越好。溫度太低，發(fā)動機不易啟動，也影響混合器的控制。如果最低的環(huán)境溫度低于發(fā)動機要求的環(huán)境溫度，則需要設(shè)計循環(huán)空氣通道，利用機房空氣熱量加熱進入發(fā)動機的空氣，滿足發(fā)動機運行的溫度要求。

　　The lower the ambient temperature of the engine, the better. The temperature is too low, making it difficult to start the engine and affecting the control of the mixer. If the minimum ambient temperature is lower than the required ambient temperature of the engine, a circulating air channel needs to be designed to use the heat of the engine room air to heat the air entering the engine and meet the temperature requirements for engine operation.

　　4、 濕度

　　4. Humidity

　　溫度高的空氣中含有較多的水分。渦輪增壓的發(fā)動機中冷器在將空氣冷卻的過程中會將大量的水積集在中冷器。而空氣中的水分通常具有腐蝕性，因此應(yīng)該選擇不銹鋼的中冷器來加強其抗腐蝕的能力，延長其使用壽命。

　　The air with high temperature contains more moisture. The intercooler of a turbocharged engine will accumulate a large amount of water in the intercooler during the process of cooling the air. The moisture in the air is usually corrosive, so stainless steel intercoolers should be chosen to enhance their corrosion resistance and extend their service life.

　　5、 粉塵

　　5. Dust

　　如果環(huán)境條件為多粉塵的環(huán)境，為了加強發(fā)動機空氣過濾器的過濾能力，需選擇重型空氣濾清器。

　　If the environmental conditions are dusty, in order to enhance the filtering ability of the engine air filter, a heavy-duty air filter should be selected.

　　在多粉塵的環(huán)境中，發(fā)電機也需要加裝空氣過濾器，防止粉塵進入發(fā)電，影響發(fā)電機的絕緣性能。

　　In dusty environments, generators also need to be equipped with air filters to prevent dust from entering the power generation and affecting the insulation performance of the generator.

　　6、 海洋腐蝕

　　6. Marine corrosion

　　如果項目現(xiàn)場臨海安裝，由于海洋空氣中含有不同含量的鹽，長時間以來，鹽將與銅發(fā)生化學(xué)反應(yīng)而導(dǎo)致腐蝕。根據(jù)海洋中鹽量成分的含量需對發(fā)電機組進行防腐處理，特別是含銅的發(fā)電機和散熱水箱。

　　If the project is installed near the sea, due to the varying levels of salt in the ocean air, salt will react chemically with copper over time, leading to corrosion. According to the salt content in the ocean, anti-corrosion treatment should be carried out on the generator set, especially for copper containing generators and cooling water tanks.
