煤炭是電力生產(chǎn)中最大的單一能源，而且其份額還在增長(zhǎng)。將煤炭轉(zhuǎn)化為電力的效率至關(guān)重要:更高效的發(fā)電廠使用更少的燃料，排放更少的對(duì)氣候有害的二氧化碳。這本書探討了如何在燃煤發(fā)電廠測(cè)量和報(bào)告效率。由于使用了許多不同的方法來表示效率性能，因此常常很難對(duì)工廠進(jìn)行比較，甚至在考慮到諸如煤質(zhì)和冷卻水溫度等任何固定約束之前也是如此。提出了實(shí)用的準(zhǔn)則，允許任何工廠的效率和排放報(bào)告在一個(gè)共同的基礎(chǔ)上，并與最佳做法進(jìn)行比較。建議建立一個(gè)全球工廠業(yè)績(jī)數(shù)據(jù)庫(kù)，以便查明表現(xiàn)不佳的工廠加以改進(jìn)。有了這些信息，政策制定者就能更好地進(jìn)行監(jiān)測(cè)，并在必要時(shí)對(duì)煤炭發(fā)電進(jìn)行監(jiān)管。所述的工具和技術(shù)對(duì)任何對(duì)更可持續(xù)利用煤炭感興趣的人都有價(jià)值。
Coal is the biggest single source of energy for electricity production and its share is growing. The efficiency of converting coal into electricity matters: more efficient power plants use less fuel and emit less climate-damaging carbon dioxide. This book explores how efficiency is measured and reported at coal-fired power plants. With many different methods used to express efficiency performance, it is often difficult to compare plants, even before accounting for any fixed constraints such as coal quality and cooling-water temperature. Practical guidelines are presented that allow the efficiency and emissions of any plant to be reported on a common basis and compared against best practice. A global database of plant performance is proposed that would allow under-performing plants to be identified for improvement. Armed with this information, policy makers would be in a better position to monitor and, if necessary, regulate how coal is used for power generation. The tools and techniques described will be of value to anyone with an interest in the more sustainable use of coal.
