資料簡介

煤炭作為能源供應(yīng)組成部分的價值,在最近的一些事件中得到了突顯,比如2000/1年冬季的北美電力危機(jī)(加州尤為突出),以及2001年9月11日的恐怖主義事件之后,人們感覺其脆弱性有所增強(qiáng)。在一個運(yùn)轉(zhuǎn)良好的市場中,人們可以從多種來源獲得一種安全的能源。然而,燃煤發(fā)電的排放問題仍然存在:CIAB和國際能源機(jī)構(gòu)一致認(rèn)為,以社會能夠承受的方式解決這個問題至關(guān)重要。加快煤氣化聯(lián)合循環(huán)系統(tǒng)、超臨界和超超臨界蒸汽循環(huán)系統(tǒng)等新發(fā)電技術(shù)的應(yīng)用,將有助于克服現(xiàn)有燃煤發(fā)電技術(shù)在熱效率和排放控制方面的限制。甚至更先進(jìn)的技術(shù),如自動減支,現(xiàn)在也備受關(guān)注。

The value of coal as a component of energy supply has been underlined by recent events, such as the North American power crisis in winter 2000/1 (with California standing out), and the perception of heightened vulnerabilityafter the terrorist events of 11 September 2001. There is a premium to be attached to a secure form of energy, available from diverse sources in a wellfunctioning market. However there remains the issue of emissions from coal-fired generation: the CIAB and IEA are in agreement that it is essential to address the question in a way society can afford. Accelerating the deployment of new power generation technologies, such as integrated coal gasification combined-cycle systems, or supercritical and ultra-supercritical steam cycle systems, will help overcome limits in thermal efficiency and emissions control from current coal-based power generation technology. Even more advanced technologies, such as sequestration, are now commanding attention.
