        這篇非常簡短的白皮書說明了為什么所有認真考慮降低發電行業碳排放的國家或者地區應該在其可再生能源發電組合中使用顆粒替代煤炭。

        This very brief white paper illustrates why all countries, states, or provinces that are serious about lowering carbon emissions in the power generation sector should include the use of pellets as a replacement for coal in their portfolio for renewable generation.

        FutureMetrics多年來發表了大量關于減少電力行業二氧化碳排放的解決方案,其中包括顆粒共燒或全燒的白皮書。

        FutureMetrics has published numerous white papers over the years about the efficacy of including pellet co-firing or full-firing in the menu of solutions for reducing CO2 emissions in the power sector.

         

        FutureMetrics之前發布的白皮書還說明了為什么顆粒燃料是低碳燃料。這篇簡短文章展示了在燃煤發電站使用顆粒燃料如何成為一部分解決方案的真實例子。

        FutureMetrics’ white papers have also shown why pellet fuel is a low carbon solution. This short paper shows a real-world example of how pellet fueled pulverized coal power stations can be part of the solution.

         

        下圖來自上周,顯示了英格蘭的發電組合。

        The chart below is from this past week and shows the generation mix in England.

        目前,英國顆粒產生的大部分電力來自Drax發電站。Drax發電站有6個645兆瓦的發電機組,其中4個完全轉換為使用木屑顆粒燃料。396兆瓦的Lynemouth發電站也已從煤炭轉變為使用顆粒。

        Currently, most of the power generated from pellets in the UK is by Drax Power. The Drax power station has six 645 megawatt units. Four of the six units are fully converted to use wood pellet fuel. The 396 megawatt Lynemouth power station has also been converted from coal to pellets.

         

        在上面的圖表中,人們可以清楚地看到風(淺綠色)如何在一周的早期沒有吹,當然,太陽(黃色)從不在夜間閃耀。此外,顆粒發電正在承擔一些峰值負荷,這降低了使用煤和天然氣的需要。

        In the chart above one can clearly see how the wind (light green) did not blow early in the week and, of course, the sun (yellow) never shines at night. Furthermore, power generation by pellets is taking some of the peaking load which lowers the need to use the coal and natural gas.

         

        來自阿格斯(Argus Direct)2018年10月25日資訊:與去年相比,英國強勁生物質電力輸出減少了一些聯合循環燃氣輪機(CCGT)的輸出,而英國公用事業公司Drax在高峰負荷時間內一直在提高電力輸出獲取更高的價格。本月到目前為止,生物質電力輸出平均為2.3GW。

        From Argus Direct on October 25, 2018: Strong UK biomass output this month has pushed some combined-cycle gas turbines (CCGTs) out of the generation mix compared with last year, and UK utility Drax has been ramping up output during peak-load hours to capture higher prices. Biomass output has averaged 2.3GW so far this month.

        由于645MW Drax機組和396MW Lynemouth發電站從煤炭到生物質的轉換,生物質裝機容量同比增加約1.1GW,總容量達到3.2GW左右。

        Installed biomass capacity is around 1.1GW higher year on year because of the conversion from coal to biomass of the 645MW Drax unit 4 and the 396MW Lynemouth plant, taking total capacity to around 3.2GW.

         

        CCGT的平均輸出為12.4GW,低于2017年10月的13.5GW。

        Output from CCGTs has averaged 12.4GW, down from 13.5GW in October 2017.

         

        這清楚地表明,使用可再生的低碳顆粒燃料發電可提供可靠的按需基本負載和峰值容量。

        This clearly demonstrates that using renewable low-carbon pellet fuel for power generation provides reliable on-demand baseload and peaking capacity.

         

        該策略是產生可再生熱能的唯一途徑,其不受不可控因素和間歇性的影響。

        This strategy is the only pathway for generating renewable thermal power that does not suffer from uncontrolled variability and intermittency.
