一、高氫煉化尾氣氣體特點   在化工過程產生中會生產大量的可燃尾氣，同樣，采用垃圾處理設備裂解生活或工業垃圾時也產生含氫的廢氣，該可燃尾氣的特點：成分復雜、含氫量高、熱值低、易爆、處理成本高、利用難度大。在沒有選擇合適的應用方式時，大部分的企業很多采用直接排空、火炬燃燒、燒鍋爐方式，這樣就造成了能源浪費，同時企業可能會受到環保處罰并要求整改。

　　1、 The characteristics of high hydrogen refining tail gas are that a large amount of combustible tail gas is produced in chemical processes. Similarly, when using waste treatment equipment to crack domestic or industrial waste, hydrogen containing exhaust gas is also produced. The characteristics of this combustible tail gas are: complex composition, high hydrogen content, low calorific value, explosive, high treatment cost, and difficult utilization. Without selecting the appropriate application method, most enterprises adopt direct emptying, torch combustion, and boiler burning methods, which results in energy waste. At the same time, enterprises may be subject to environmental penalties and required to rectify.

　　二、高氫煉化尾氣發電機組   針對煉化尾氣氣源，專門研制了利用該氣源的發電機組。針對燃氣易回火和爆震的特點，采用了全新的進氣方式、排氣方式和空燃比控制方式，進行了全新的設計并經過耐久性試驗。機組從安全性和利用效率兩方面解決了多年來對此類燃氣利用的難題，廣泛應用于焦爐煤氣、高爐煤氣、蘭炭氣、甲醇馳放氣、化工裂解氣、垃圾氣等各類煉化、垃圾處理等領域，開創了可燃煉化尾氣和垃圾裂解氣利用的新市場。   按照尾氣中主要可燃成分區分，可分為兩種：一種以焦化尾氣、化工馳放氣為代表，其氣體中氫氣含量較高的（含氫氣高于30%直至100%，且其它可燃成分低于氫氣），可選用高氫燃氣機組發電利用；一種是氫含量較少（含氫氣低于 30%，且其它可燃成分高于氫氣），可選用低氫燃氣機組發電利用。SK500H2、SK600H2、SK700H2型氫氣發電機組技術規格備注：也可以定制60HZ發電機組。

　　2、 A high hydrogen refining tail gas generator set has been specially developed to utilize the refining tail gas source. In response to the characteristics of gas flashback and detonation, a new intake method, exhaust method, and air-fuel ratio control method have been adopted, and a new design has been carried out and durability tests have been conducted. The unit has solved the long-standing problems in the utilization of this type of gas from both safety and utilization efficiency aspects, and has been widely used in various refining and waste treatment fields such as coke oven gas, blast furnace gas, blue charcoal gas, methanol release gas, chemical cracking gas, garbage gas, etc. It has opened up a new market for the utilization of combustible refining tail gas and garbage cracking gas. According to the main combustible components in exhaust gas, it can be divided into two types: one is represented by coking exhaust gas and chemical exhaust gas, which have a high hydrogen content in the gas (including hydrogen content higher than 30% to 100%, and other combustible components lower than hydrogen), and can be used for power generation with high hydrogen gas turbines; One option is to use low hydrogen gas turbines for power generation and utilization, as the hydrogen content is relatively low (with less than 30% hydrogen and other combustible components higher than hydrogen). Technical specifications for SK500H2, SK600H2, and SK700H2 hydrogen generator sets: Customized 60HZ generator sets are also available.

　　三、機組主要技術特點及安全性保證措施3.1進氣隔離技術   采用燃氣和空氣隔離的進氣技術，空氣經增壓器壓氣后進入左、右進氣管，燃氣由各缸燃氣閥獨立供氣?？諝夂腿細庠谶M入發動機缸內混合，在進氣管內沒有空氣和燃氣的混合燃氣，防止了進氣管的回火放炮，保證了進氣系統的運行安全。3.2 純空氣掃氣技術   采用純空氣對燃燒室掃氣的技術，避免了未燃燒的混合燃氣進入排氣管，防止排氣管爆燃放炮，保證排氣系統、增壓器的運行安全（在電站運行現場，機組的運行平穩性及聲音和天然氣機組一樣）；同時，由于只有空氣而沒有燃氣掃氣，減少了燃氣的損失，提高了燃氣發電的利用效率。3.3 自動控制空燃比技術   自動控制空燃比，確保機組運行在最合理的空燃比范圍，保障機組穩定運行，減少人工的干預，同時提高了發動機的燃燒做功效率。3.4 抗爆震技術   采用大能量點火系統、降低壓縮比、中冷技術和空燃比控制技術，抑制了氫氣的爆震。3.5 機組轉速   機型轉速為 1000r/min，相對于 1500r/min 高速機，降低了機械部件的運動沖擊，延長了機組的使用壽命，減少了配件消耗，保證了用戶長期運行的效益。3.6 機組自動化   機組自動化程度高，人工操作和維修強度低，運行成本低。3.7 電站廠房通風設計及安全性保證   發電機房安裝軸流風機強制通風，防止有毒氣體和可燃氣體在機房內積聚;發電機房內配置可燃氣體、有毒氣體報警裝置，與機房軸流風機聯動，報警后觸發軸流風機啟動進行強制通風，保證機房內可燃氣體、有毒氣體含量不超標，滿足安全要求。   氫氣的密度是所有氣源中最低的，遠遠低于空氣，在開放式空間其擴散性非常好，因而，只要通風設計合格，其安全性高于天然氣。   發動機設計有特殊的進排氣結構，發動機汽缸外沒有可燃混合燃氣，由此保證了發動機的本質安全。四、氣體成分要求   高氫氣發電機組氣源要求：在距離機組燃氣進氣調壓閥或機組配套壓縮機前 1m 內：燃氣氣溫度 10℃～40℃；壓力 0.20 MPa 至 0.30MPa,壓力變化速率≤1kPa/min；粉塵粒度≤5μm，粉塵含量≤30mg/Nm3；總硫含量≤400mg/Nm3，H2S≤200mg/Nm3；總水分含量≤40g/Nm3，無明顯游離水；NH3≤20mg/Nm3；焦油含量≤20mg/Nm3；苯含量≤4g/Nm3；萘含量≤100g/Nm3；總鹵素化合物含量≤100mg/Nm3；燃氣中 H2 體積 含量≤100%、≥30%，熱值變化率≤5%/min。五、應用案例工程

　　3、 Main technical characteristics and safety assurance measures of the unit 3.1 Intake isolation technology adopts gas and air isolation intake technology. The air is compressed by the supercharger and enters the left and right intake pipes, and the gas is independently supplied by the gas valves of each cylinder. Air and gas mix when entering the engine cylinder, and there is no mixture of air and gas in the intake pipe, which prevents backfire and ensures the safe operation of the intake system. 3.2 Pure air scavenging technology uses pure air to sweep the combustion chamber, avoiding unburned mixed gas from entering the exhaust pipe, preventing the exhaust pipe from exploding and firing, and ensuring the safe operation of the exhaust system and turbocharger (at the power plant operation site, the stability and sound of the unit are the same as natural gas units); Meanwhile, due to the presence of only air without gas scavenging, the loss of gas is reduced and the utilization efficiency of gas-fired power generation is improved. 3.3 Automatic control air-fuel ratio technology automatically controls the air-fuel ratio to ensure that the unit operates within the most reasonable air-fuel ratio range, guarantees stable operation of the unit, reduces manual intervention, and improves the combustion efficiency of the engine. 3.4 Anti knock technology adopts high-energy ignition system, reduced compression ratio, intercooler technology, and air-fuel ratio control technology to suppress hydrogen detonation. The speed of the 3.5 unit model is 1000r/min. Compared to the 1500r/min high-speed machine, it reduces the motion impact of mechanical components, extends the service life of the unit, reduces accessory consumption, and ensures the long-term operation benefits of users. 3.6 Unit automation: The unit has a high degree of automation, low manual operation and maintenance intensity, and low operating costs. 3.7 Ventilation design and safety assurance for power plant buildings: Install axial flow fans for forced ventilation in the generator room to prevent the accumulation of toxic and flammable gases in the room; The generator room is equipped with combustible gas and toxic gas alarm devices, which are linked with the axial flow fan in the machine room. After the alarm is triggered, the axial flow fan is started for forced ventilation to ensure that the combustible gas and toxic gas content in the machine room does not exceed the standard and meets safety requirements. The density of hydrogen is the lowest among all gas sources, far lower than that of air, and its diffusion is very good in open spaces. Therefore, as long as the ventilation design is qualified, its safety is higher than that of natural gas. The engine design has a special intake and exhaust structure, and there is no combustible mixed gas outside the engine cylinder, thereby ensuring the intrinsic safety of the engine. 4、 Gas composition requirements for high hydrogen power generation units: Gas source requirements: Within 1 meter in front of the unit's gas inlet pressure regulating valve or the unit's supporting compressor: Gas temperature of 10 ℃ to 40 ℃; Pressure ranging from 0.20 MPa to 0.30 MPa, with a pressure change rate of ≤ 1kPa/min; Dust particle size ≤ 5 μ m, dust content ≤ 30mg/Nm3; Total sulfur content ≤ 400mg/Nm3, H2S ≤ 200mg/Nm3; Total moisture content ≤ 40g/Nm3, with no obvious free water; NH3≤20mg/Nm3； Tar content ≤ 20mg/Nm3; Benzene content ≤ 4g/Nm3; Naphthalene content ≤ 100g/Nm3; Total halogen compound content ≤ 100mg/Nm3; The volume content of H2 in gas is ≤ 100%, ≥ 30%, and the rate of change in calorific value is ≤ 5%/min. 5、 Application Case Engineering

At the same time, the exhaust temperature is too high, shortening the service life of the exhaust pipe and turbocharger.
