Gas generator units are widely used in natural gas power generation, biogas power generation, landfill gas power generation and other fields due to their good fuel adaptability, high power generation efficiency, flexible unit operation mode and other characteristics. In several common types of fuel gas, due to different sources and processes of fuel gas, fuel gas often contains a variety of impurities. The following is a brief analysis of several common impurity types.
1、顆粒物
1. Particulate matter
粉塵等固體顆粒物對燃?xì)獍l(fā)電機(jī)組的影響，主要在于造成過濾器堵塞、進(jìn)氣量不足和壓力降低等。在發(fā)動機(jī)氣缸內(nèi)部會造成缸壁和活塞磨損，同時也會污染潤滑油，進(jìn)而造成其他部件如滑動軸承的磨損，影響機(jī)組的正常運(yùn)行。
The impact of solid particles such as dust on gas turbine generator units mainly lies in filter blockage, insufficient air intake and pressure reduction. In the engine cylinder, the cylinder wall and piston will be worn, and at the same time, the lubricating oil will be polluted, which will cause the wear of other components, such as sliding bearings, and affect the normal operation of the unit.
、發(fā)動機(jī)燃?xì)膺M(jìn)氣閥組自帶的過濾器僅用于保護(hù)系統(tǒng)不受顆粒物損壞，不能作為工作負(fù)荷過濾器。用戶應(yīng)在燃?xì)夤苈吩O(shè)置工作負(fù)荷過濾器，且過濾器在顆粒直徑大于3μm時，低分離率須達(dá)到99.99%或以上。
The filter attached to the engine gas inlet valve group is only used to protect the system from particle damage, and cannot be used as the working load filter. The user shall set a working load filter in the gas pipeline, and the filter shall be set with a particle diameter greater than 3 μ M, the low separation rate must reach 99.99% or above.

2、硫

Fuel gas such as biogas often contains sulfur compounds such as hydrogen sulfide, which will form sulfur dioxide and sulfur trioxide if burned in the cylinder. As the fuel gas contains water and the fuel gas combustion will also produce water, sulfur compounds dissolve in water to form hydrosulfuric acid, sulfite and sulfuric acid, which will corrode the metal parts of the engine.

The specific requirements for the sulfur content of the gas in the gas generator set are related to the unit model and the gas methane concentration. Generally, the total sulfur content in the gas entering the engine should be less than 300mg/Nm3. In addition, models with precombustion chambers usually have additional requirements. If there is tail gas treatment equipment with catalyst, the sulfur content requirements of catalyst shall also be considered.
3、油
3. Oil
由于不同的運(yùn)行溫度和熱化學(xué)反應(yīng)過程，生物質(zhì)熱解和氣化過程中會產(chǎn)生成百上千種不同類別的焦油。通常，此類碳?xì)浠衔镌诘蜏赜隼鋾r凝結(jié)成液態(tài)，會堵塞進(jìn)氣系統(tǒng)、渦輪增壓器葉片和中冷器等。對生物質(zhì)熱解氣進(jìn)行預(yù)處理后，對其中焦油的露點(diǎn)進(jìn)行分析是一個行之有效的方法。
Due to different operating temperatures and thermochemical reaction processes, hundreds of different types of tar will be produced during biomass pyrolysis and gasification. Usually, such hydrocarbons will be condensed into liquid when they are cold at low temperature, which will block the intake system, turbocharger blades, intercoolers, etc. It is an effective method to analyze the dew point of tar after pretreatment of biomass pyrolysis gas.
這類雜質(zhì)對發(fā)電機(jī)組帶來的危害將逐漸累積，并對機(jī)組的運(yùn)行效果，正常維護(hù)間隙甚至使用壽命產(chǎn)生非常深遠(yuǎn)的負(fù)面影響。因此，通過預(yù)處理方式去除或減少燃?xì)庵械碾s質(zhì)非常重要，且需按照燃?xì)獍l(fā)電機(jī)組制造商的技術(shù)要求和建議來進(jìn)行。更多相關(guān)內(nèi)容就來我們網(wǎng)站http://www.a7716.cn進(jìn)行咨詢！
The harm brought by such impurities to the generator set will gradually accumulate, and have a very far-reaching negative impact on the operating effect, normal maintenance clearance and even service life of the unit. Therefore, it is very important to remove or reduce impurities in the gas by pretreatment, and it should be carried out according to the technical requirements and recommendations of the gas generator set manufacturer.
