　　1. Project Source and Background

　　煤炭、化工和金屬冶煉企業,在生產過程中,會產生大量煉化尾氣。這些尾氣中大都含有氫氣、一氧化碳、少量甲烷,還有其它一些烴類等可燃成分。以焦爐煤氣為例,有關專家指出,中國的鋼鐵生產能力在進行戰略調整的同時,仍有較大的發展空間。這意味著目前作為鋼鐵生產必不可缺的焦化產業仍具有廣闊的發展前景。據不完全統計,年直接空排或空燒的煉焦煤氣達到200億立方米以上,相當于西氣東送工程的年輸氣量。隨著西氣東送工程的實施,由于焦爐煤氣與天然氣的不可比性,國內目前管道煤氣30～40％將被管道天然氣取代,一些焦化企業的煤氣將逐漸退出民用領域,這又意味著更多的煤氣無地可去。焦爐煤氣的主要成分為氫氣和甲烷,排往空中無疑將使生態環境遭到破壞。 煉化尾氣氣體成分復雜,尤其是易燃易爆的高氫尾氣,企業再利用度低,絕大部分都直接排空放散或者通過火炬燒掉,造成大的環境污染和資源浪費。在當今提倡環保和節約的社會形勢下,工業煉化尾氣如何尋求合理的利用方式,變廢為寶,提高企業效益,變成一個亟待解決的問題。 淄博淄柴新能源有限公司自主研發的高氫煉化尾氣發電機組,以氫氣含量高的焦爐煤氣、電石尾氣、蘭炭氣等為原料,驅動發動機帶動發電機工作。該型機組通過針對性的設計,使整機性能得到充分發揮。與同類產品相比具有明顯優勢：具備功率大、可靠性高、物料消耗省、各缸排氣溫度較低、易維護等特點,機組各技術指標已處于國際先進、國內領先地位。500kW高氫煉化尾氣發電機組的成功研發,將為煉化尾氣在內燃發電行業的應用提供新的思路,必將推動煉化尾氣在內燃發電行業的快速發展。

　　Coal, chemical, and metal smelting enterprises generate a large amount of refining exhaust gas during the production process. Most of these exhaust gases contain combustible components such as hydrogen, carbon monoxide, a small amount of methane, and other hydrocarbons. Taking coke oven gas as an example, experts point out that while China's steel production capacity is undergoing strategic adjustments, there is still significant room for development. This means that the coking industry, which is essential for steel production, still has broad development prospects. According to incomplete statistics, the annual direct discharge or combustion of coking gas exceeds 20 billion cubic meters, which is equivalent to the annual gas transmission volume of the West East Gas Pipeline Project. With the implementation of the West East Gas Transmission Project, due to the incomparability between coke oven gas and natural gas, 30-40% of pipeline gas in China will be replaced by pipeline natural gas. Some coking enterprises' gas will gradually withdraw from the civilian field, which means that more gas has nowhere to go. The main components of coke oven gas are hydrogen and methane, and discharging them into the air will undoubtedly damage the ecological environment. The gas composition of refining tail gas is complex, especially the highly flammable and explosive high hydrogen tail gas, which has low enterprise reuse. The vast majority of it is directly discharged or burned through torches, causing great environmental pollution and resource waste. In today's society that advocates environmental protection and conservation, how to seek reasonable utilization of industrial refining exhaust gas, turn waste into treasure, and improve enterprise efficiency has become an urgent problem to be solved. The high hydrogen refining tail gas generator set independently developed by Zibo Zichai New Energy Co., Ltd. uses high hydrogen content coke oven gas, calcium carbide tail gas, orchid charcoal gas and other raw materials to drive the engine and generator to work. This type of unit achieves full performance through targeted design. Compared with similar products, it has obvious advantages: it has the characteristics of high power, high reliability, low material consumption, low exhaust temperature of each cylinder, and easy maintenance. The technical indicators of the unit are already in an internationally advanced and domestically leading position. The successful development of a 500kW high hydrogen refining tail gas generator set will provide new ideas for the application of refining tail gas in the internal combustion power generation industry, and will undoubtedly promote the rapid development of refining tail gas in the internal combustion power generation industry.

　　2 項目的目的與意義

　　The purpose and significance of the two projects

　　隨著石油資源的逐漸枯竭和全球環境的惡化,世界各國不得不尋找其它儲量豐富、廉價、低污染的代用燃料。另外,隨著中國天然氣的開發、“西氣東送”工程的啟動和大量獨立冶煉企業的建設,煉化尾氣已開始出現過剩,且因成分復雜難以回收利用,多數企業直接將其排空放散,造成資源的浪費和環境的污染。以煉化尾氣為原料代替昂貴而又緊張的石油、天然氣等資源的燃氣發電設備的開發利用,能夠降低對石油、天然氣等能源的依賴,提高經濟效益,同時又可大消除對環境的污染。因此,該項目的實施具備大的市場需求潛力,市場推廣前景廣闊。 高氫煉化尾氣發電機組將300系列機型固有優勢與進氣系統內混新技術相結合,大膽進行技術創新,并通過實踐驗證,機組功率高、穩定性好、安全可靠、技術成熟。該系列機組為非增壓自然吸氣式直列機,額定轉速600r/min,額定功率500kW,高、中、低壓輸出皆可。該發電技術取得行業內重大突破,技術水平達到國際先進,同時該機型的開發符合國家的能源產業政策,帶有很強的技術前瞻性,具備大的市場需求潛力。

　　With the gradual depletion of oil resources and the deterioration of the global environment, countries around the world have to seek alternative fuels that are abundant in reserves, cheap, and low polluting. In addition, with the development of natural gas in China, the launch of the "West East Gas Transmission" project, and the construction of a large number of independent smelting enterprises, there has been an excess of refining tail gas, which is difficult to recycle due to its complex composition. Most enterprises directly discharge it, causing waste of resources and environmental pollution. The development and utilization of gas-fired power generation equipment using refined exhaust gas as raw material to replace expensive and scarce resources such as oil and natural gas can reduce dependence on energy such as oil and natural gas, improve economic efficiency, and greatly eliminate environmental pollution. Therefore, the implementation of this project has great potential for market demand and broad prospects for market promotion. The high hydrogen refining tail gas generator unit combines the inherent advantages of the 300 series models with the new mixed technology in the intake system, boldly innovates the technology, and has been verified through practice to have high power, good stability, safety and reliability, and mature technology. This series of units is a non pressurized naturally aspirated inline unit with a rated speed of 600r/min and a rated power of 500kW. It can output high, medium, and low voltage. This power generation technology has achieved significant breakthroughs in the industry, reaching an internationally advanced level of technology. At the same time, the development of this model is in line with the national energy industry policy, with strong technological foresight and great market demand potential.

　　We have independently developed a single cylinder controllable internal hybrid intake system, which achieves the isolation of gas and air outside the cylinder and the mixing combustion inside the cylinder, effectively avoiding the backfire and blasting phenomena that are prone to occur when using this type of high hydrogen gas. At the same time, the gas intake of each cylinder can be controlled separately to ensure the uniformity of intake and more stable operation of the unit. By adaptively developing key technologies and adopting complete and reliable measures for gas safety utilization such as fire prevention, explosion prevention, and leak prevention, the developed refining tail gas generator set can be applied to gas with a hydrogen content of up to 60%, solving the technical problem of internal combustion power generation of high hydrogen content combustible gases such as coke oven gas, calcium carbide tail gas, and blue carbon gas. At the same time, customized development of automation control and remote monitoring systems can achieve automation functions such as rapid response, one key start, automatic closing, and automatic loading of gas generator sets and their peripheral supporting equipment, facilitating remote monitoring operations. This system can adjust the operation status of the gas generator set in a timely manner according to changes in the gas source, achieving unmanned operation, more convenient operation, and smoother operation.

　　5 存在的問題和改進意見

　　5 Existing Problems and Improvement Suggestions

　　目前,500kW高氫煉化尾氣發電機組單機功率較低,無法滿足大規模發電利用工程建設的需求。 研發團隊還將繼續致力于優化機組性能,提升機組運行功率,或者開發更大功率機型,以適應更加廣闊的市場需求。

　　At present, the single unit power of 500kW high hydrogen refining tail gas generator set is relatively low, which cannot meet the needs of large-scale power generation and utilization engineering construction. The R&D team will continue to work on optimizing unit performance, improving unit operating power, or developing larger power models to meet broader market demands.
