天然氣發(fā)電機組：零碳復(fù)溫壓差發(fā)電破局，年發(fā)電330萬度，盤活管網(wǎng)廢棄壓力能

　　Natural gas generator set: Zero carbon reheating pressure differential power generation breaks the deadlock, generating 3.3 million kWh annually and activating waste pressure energy in the pipeline network

　　天然氣管網(wǎng)運輸與調(diào)壓環(huán)節(jié)長期存在兩大行業(yè)痛點：高壓天然氣長途輸送后需大幅降壓適配下游用戶，海量壓力能通過調(diào)壓閥白白損耗；傳統(tǒng)調(diào)壓后需依賴燃氣、電加熱復(fù)溫，不僅消耗額外能源，還產(chǎn)生碳排放，冬季更面臨管道結(jié)冰堵管風(fēng)險。如今，全球首套**零碳復(fù)溫天然氣壓差發(fā)電機組**在山東曲阜正式投運，徹底打破這一困局，這套由中科院工程熱物理研究所自主研發(fā)的核心裝備，將管網(wǎng)廢棄壓力能高效轉(zhuǎn)化為零碳電能，年發(fā)電量突破330萬度，實現(xiàn)“壓力回收+零碳發(fā)電+防凍復(fù)溫”三重突破，成為天然氣場站綠色轉(zhuǎn)型、能源高效利用的標(biāo)桿方案。

　　There are two major industry pain points in the transportation and pressure regulation of natural gas pipeline networks for a long time: after long-distance transmission of high-pressure natural gas, it needs to be significantly reduced in pressure to adapt to downstream users, and massive pressure can be wasted through pressure regulating valves; Traditional pressure regulation relies on gas and electric heating for reheating, which not only consumes additional energy but also generates carbon emissions, and faces the risk of pipeline icing and blockage in winter. Now, the world's first zero carbon reheating natural gas pressure differential generator set has been officially put into operation in Qufu, Shandong, completely breaking this dilemma. This core equipment, independently developed by the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, efficiently converts waste pressure energy from pipeline networks into zero carbon electricity, with an annual power generation exceeding 3.3 million kWh, achieving a triple breakthrough of "pressure recovery+zero carbon power generation+antifreeze reheating", and becoming a benchmark solution for green transformation and energy efficient utilization of natural gas stations.

　　壓差能源長期浪費，傳統(tǒng)調(diào)壓模式弊端凸顯

　　Long term waste of differential pressure energy, highlighting the drawbacks of traditional pressure regulation mode

　　天然氣長途管道運輸需維持高壓，以克服摩擦阻力、提升輸送流量，而抵達終端門站后，下游用戶用氣壓力遠低于輸送壓力，必須進行降壓處理。長期以來，行業(yè)普遍采用調(diào)壓閥節(jié)流降壓，直接將寶貴的壓力能無償耗散，這部分被浪費的能源體量驚人，卻始終未得到有效利用。同時，天然氣節(jié)流降壓過程中會急劇降溫，冬季極易導(dǎo)致管道、閥門結(jié)冰堵塞，影響供氣安全，傳統(tǒng)解決方案依賴天然氣燃燒或電加熱復(fù)溫，不僅增加場站運營成本，還額外產(chǎn)生碳排放，違背雙碳發(fā)展目標(biāo)，也拉高了場站能耗指標(biāo)。

　　Long distance natural gas pipeline transportation requires maintaining high pressure to overcome frictional resistance and increase transmission flow. However, after reaching the terminal station, downstream users use air pressure much lower than the transmission pressure and must undergo depressurization treatment. For a long time, the industry has commonly used pressure regulating valves to throttle and reduce pressure, directly dissipating valuable pressure energy for free. The amount of wasted energy is astonishing, but it has never been effectively utilized. At the same time, during the process of natural gas throttling and pressure reduction, the temperature drops sharply, which can easily cause pipeline and valve icing and blockage in winter, affecting gas supply safety. Traditional solutions rely on natural gas combustion or electric heating for reheating, which not only increases the operating costs of the station, but also generates additional carbon emissions, violating the dual carbon development goal and raising the energy consumption index of the station.

　　這套零碳復(fù)溫天然氣壓差發(fā)電機組的問世，精準(zhǔn)破解上述難題，它摒棄傳統(tǒng)調(diào)壓閥耗能模式，將廢棄壓力能轉(zhuǎn)化為高品位電能，同時通過原創(chuàng)技術(shù)實現(xiàn)零碳復(fù)溫，既保障供氣安全，又實現(xiàn)能源回收，填補了國內(nèi)乃至國際天然氣壓差零碳發(fā)電的技術(shù)空白，核心裝備與工藝實現(xiàn)100%自主化，擺脫對外技術(shù)依賴。

　　The emergence of this zero carbon reheating natural gas pressure difference generator set accurately solves the above problems. It abandons the traditional energy consumption mode of pressure regulating valves, converts waste pressure energy into high-grade electrical energy, and achieves zero carbon reheating through original technology, which not only ensures gas supply safety but also realizes energy recovery, filling the technical gap of zero carbon power generation in natural gas pressure difference at home and even internationally. The core equipment and process are 100% independent, getting rid of external technological dependence.

　　核心技術(shù)突破：零碳復(fù)溫+壓差發(fā)電，全流程綠色高效

　　Core technological breakthrough: zero carbon reheating+differential pressure power generation, green and efficient throughout the entire process

　　該款天然氣發(fā)電機組以壓差能量回收為核心，搭配獨創(chuàng)零碳復(fù)溫技術(shù)，構(gòu)建“壓力轉(zhuǎn)化-發(fā)電做功-零碳復(fù)溫”全閉環(huán)流程，運行全程無額外燃料消耗、零碳排放，區(qū)別于傳統(tǒng)天然氣燃燒發(fā)電，屬于純物理能量回收，環(huán)保效益與能源效益雙重拉滿。高壓天然氣首先進入機組膨脹機，通過壓力勢能驅(qū)動膨脹機葉輪高速旋轉(zhuǎn)，將壓力能轉(zhuǎn)化為機械能，進而帶動發(fā)電機運轉(zhuǎn)輸出電能，完成廢棄壓力到清潔電力的高效轉(zhuǎn)化，替代傳統(tǒng)調(diào)壓節(jié)流，實現(xiàn)能源“變廢為寶”。

　　This natural gas generator set is based on pressure difference energy recovery and is equipped with a unique zero carbon reheating technology. It constructs a fully closed-loop process of "pressure conversion power generation work zero carbon reheating", with no additional fuel consumption or zero carbon emissions throughout the operation. It is different from traditional natural gas combustion power generation and belongs to pure physical energy recovery, achieving dual environmental and energy benefits. High pressure natural gas first enters the expansion turbine of the unit, which drives the high-speed rotation of the expansion turbine impeller through pressure potential energy, converts pressure energy into mechanical energy, and then drives the generator to operate and output electrical energy, completing the efficient conversion of waste pressure to clean electricity, replacing traditional pressure regulation and throttling, and realizing the "turning waste into treasure" of energy.

　　最具突破性的是**零碳復(fù)溫技術(shù)**，機組無需燃燒天然氣、無需外接電加熱，依托系統(tǒng)流程創(chuàng)新，即可在冬季將天然氣出口溫度提升至0℃以上，徹底消除管道結(jié)冰隱患，同時省去傳統(tǒng)復(fù)溫環(huán)節(jié)的能源消耗與碳排放。整套系統(tǒng)經(jīng)過甩負荷、緊急切斷等多項嚴(yán)苛測試，運行穩(wěn)定可靠，可適配天然氣管網(wǎng)變工況運行需求，既能滿足場站自身生產(chǎn)、監(jiān)控、運維等全部用電需求，多余電量還可直接并入國家電網(wǎng)，實現(xiàn)自發(fā)自用、余電上網(wǎng)。

　　The most breakthrough is the zero carbon reheating technology, which eliminates the need for natural gas combustion or external electric heating. With innovative system processes, the natural gas outlet temperature can be raised to above 0 ℃ in winter, completely eliminating the risk of pipeline icing and saving energy consumption and carbon emissions in traditional reheating processes. The entire system has undergone rigorous tests such as load shedding and emergency shutdown, and operates stably and reliably. It can adapt to the changing operating conditions of natural gas pipelines and meet all the electricity needs of the station, including production, monitoring, and operation. Excess electricity can also be directly integrated into the national power grid, achieving self use and grid connection.

　　相較于傳統(tǒng)天然氣燃燒發(fā)電機組，這款零碳壓差發(fā)電機組無需消耗天然氣燃料，純靠回收廢棄能源發(fā)電，真正實現(xiàn)零碳、零耗、高效，為能源行業(yè)循環(huán)利用、節(jié)能降碳提供了全新路徑，也為我國雙碳目標(biāo)實現(xiàn)提供了硬核技術(shù)支撐，是天然氣能源領(lǐng)域綠色轉(zhuǎn)型的核心裝備。

　　Compared to traditional natural gas combustion power generation units, this zero carbon pressure difference power generation unit does not require the consumption of natural gas fuel and relies solely on the recycling of waste energy to generate electricity, truly achieving zero carbon, zero consumption, and high efficiency. It provides a new path for the energy industry's circular utilization, energy conservation, and carbon reduction, and also provides hardcore technical support for China's dual carbon goals. It is the core equipment for the green transformation of the natural gas energy field.
