煤氣發(fā)電技術(shù)正經(jīng)歷著從“能發(fā)電”到“出色發(fā)電”的深刻躍遷。發(fā)電效率從傳統(tǒng)中溫中壓機組的不足30%，提升至超臨界機組的43%-45.6%，這是一條由技術(shù)創(chuàng)新鋪就的能效躍遷之路。

Gas power generation technology is undergoing a profound transition from "energy generation" to "efficient power generation". The power generation efficiency has increased from less than 30% for traditional medium temperature and medium pressure units to 43% -45.6% for supercritical units, which is a path of energy efficiency leap paved by technological innovation.

第一代煤氣發(fā)電技術(shù)采用中溫中壓參數(shù)（主蒸汽溫度450℃、壓力3.82MPa），發(fā)電效率僅25%-30%，大量熱能隨煙氣排空。第二代超高溫超高壓技術(shù)（主蒸汽溫度540℃、壓力13.7MPa）將效率提升至35%-38%。第三代超高溫亞臨界技術(shù)（主蒸汽溫度566℃、壓力17.5MPa）進一步將效率推高至40%以上。而非常新的超臨界技術(shù)（主蒸汽溫度600℃、壓力25MPa以上）實現(xiàn)了43%-45.6%的發(fā)電效率，逼近燃煤超超臨界機組的水平。

The first generation of gas power generation technology adopts medium temperature and medium pressure parameters (main steam temperature of 450 ℃, pressure of 3.82MPa), with a power generation efficiency of only 25% -30%, and a large amount of heat energy is discharged with the flue gas. The second-generation ultra-high temperature and ultra-high pressure technology (main steam temperature of 540 ℃, pressure of 13.7MPa) has increased efficiency to 35% -38%. The third-generation ultra-high temperature subcritical technology (main steam temperature 566 ℃, pressure 17.5MPa) further increases efficiency to over 40%. The latest supercritical technology (main steam temperature of 600 ℃, pressure above 25MPa) has achieved a power generation efficiency of 43% -45.6%, approaching the level of coal-fired ultra supercritical units.

在技術(shù)創(chuàng)新的推動下，煤氣發(fā)電機組正朝著小型化、模塊化、智能化方向演進。首鋼工程公司攻克了小容量高參數(shù)汽輪機設(shè)計難題，應用高轉(zhuǎn)速汽輪機配合變速齒輪箱，使機組容量覆蓋35MW至150MW，可靈活匹配不同規(guī)模鋼鐵企業(yè)的煤氣資源量。智慧電廠建設(shè)方面，結(jié)合物聯(lián)網(wǎng)、云計算、大數(shù)據(jù)、AI等技術(shù)，構(gòu)建智能運行管理、智能預警、三維可視化工廠等功能體系，實現(xiàn)電廠安全、環(huán)保、經(jīng)濟運行的全方位提升。

Driven by technological innovation, gas-fired power generation units are evolving towards miniaturization, modularity, and intelligence. Shougang Engineering Company has overcome the design challenge of small capacity high parameter steam turbines by using high-speed steam turbines combined with variable speed gearboxes to cover unit capacities ranging from 35MW to 150MW, which can flexibly match the gas resources of steel enterprises of different scales. In terms of the construction of smart power plants, technologies such as the Internet of Things, cloud computing, big data, and AI are integrated to build functional systems such as intelligent operation management, intelligent warning, and 3D visualization of power plants, achieving comprehensive improvement in power plant safety, environmental protection, and economic operation.

哈密煤化工產(chǎn)業(yè)采用“焦爐煤氣收集-凈化處理-出色發(fā)電”全鏈條模式，通過2×135MW超高溫亞臨界機組，熱效率從傳統(tǒng)機組的35%提升至52%，滿抽狀態(tài)下更達65.1%。這一技術(shù)突破使每立方米焦爐煤氣的發(fā)電量較常規(guī)機組提升40%。從“能發(fā)電”到“出色發(fā)電”，煤氣發(fā)電機組正在用技術(shù)的階梯，將鋼鐵廠的每一立方米煤氣都轉(zhuǎn)化為非常寶貴的電力。

The Hami coal chemical industry adopts a full chain model of "coke oven gas collection purification treatment high-efficiency power generation". Through 2 × 135MW ultra-high temperature subcritical units, the thermal efficiency is increased from 35% of traditional units to 52%, and even reaches 65.1% in full pumping state. This technological breakthrough has increased the power generation per cubic meter of coke oven gas by 40% compared to conventional units. From 'capable of generating electricity' to 'efficient power generation', gas generators are using technological advancements to convert every cubic meter of gas in steel plants into the most valuable form of electricity.
