非傳統(tǒng)能源

前言

Energy has become an important and one of the basic infrastructures for economicdevelopment of a country. Energy security is, therefore, imperative for sustained growthof economy. The oil crisis of 1973 and concern for environment due to excessive use offossil fuels have led to remarkable global efforts in harnessing alternative energy resources.The renewable energy resources such as the sun, wind, biomass and geothermal heatare environment friendly and perennial in nature. These resources are also referred asnon-conventional energy resources as, at present, their large-scale use is not common.Harnessing of energy through these resources using efficient technologies is expected toplay an important role in serving as clean energy sources for mankind. Thus, processesto harness these are steadily gaining technical and economic importance worldwide. Mostgovernments have substantial plans directed towards encouraging these technologies inorder to develop them commercially. As we had hoped and wished initially, the developmentof these technologies have not been dramatic. They have yet to achieve the cost-benefitratio possible with conventional fuels and are not likely to replace fossil fuels in the nearfuture. Nevertheless, they have come to play a very important supportive role in additionto conventional sources. Therefore, it is necessary for energy planners / users to knowthe virtues as well as limitations of these technologies. The present book is an effort t,,explore these technologies in a balanced perspective.Being a relatively recent field, the subject matter is scattered in specialized researchjournals and a few books of advanced levels are devoted exclusively to a particulartechnology. There is, however, scarcity of publications that introduce all these technologiesin a single volume to a beginner. Therefore, a natural consequence of the current volumewill be a much-needed and relatively inexpensive textbook at an undergraduate level, Whileteaching a course on non-conventional energy to undergraduate engineering students, theauthor himself felt this need, which encouraged him to write the present book.Human-resource development in the area of energy, in general, and in new andrenewable sources of energy, in particular, has been neglected all over the world, and moreso in developing countries. Therefore, the book is primarily intended to serve as textbookfor undergraduate-level courses for engineering and science students. It stresses scientificunderstanding, analysis and applications of non-conventional energy technologies. Manypracticing engineers and scientists may not have a formal exposure to this area and may beinterested to have a general training of these technologies. Therefore, the book is orientedto cover both basic study and its widespread applications. It describes the fundamentalphysical processes governing various non-conventional energy technologies and theirapplications. The book may also serve to create awareness among energy planners, policymakers and users at large about these technologies in general. Because of the spread ofdisciplines involved, it is not possible to discuss each of them exhaustively in a singlebook. Therefore, only relevant background up to a depth essential to understand the basicprin_ciples has been included.

內(nèi)容概要

　　《非傳統(tǒng)能源》（Non-Conventional Energy Resources）一書的內(nèi)容非常豐富，也比較有特色。從內(nèi)容上講，該書不僅包含了太陽能、風能、生物質(zhì)能、地熱能、海洋能、水能等可再生能源，而且對各種新型的能源利用技術，包括燃料電池、氫能、磁流體發(fā)電、熱電堆發(fā)電等進行了介紹，同時還對財務和經(jīng)濟評價方法進行了較詳細的說明。這與國內(nèi)一些院校為本科生開設的課程“可再生能源及其利用技術”或類似的課程時，也將財務和經(jīng)濟評價的內(nèi)容包括在內(nèi)的情況不謀而合。這說明對于這些非傳統(tǒng)能源，經(jīng)濟評價已經(jīng)是相當重要的一個方面。而對于每種主要的能源形式，該書都從基本理論、主要利用技術、環(huán)境特性、發(fā)展應用現(xiàn)狀等方面進行了詳細的介紹。如果作為教材或教學參考書，建議教師能夠再在技術經(jīng)濟性方面做些補充，教學內(nèi)容會更加全面?！　　斗莻鹘y(tǒng)能源（第2版）》對太陽能的介紹最為詳盡，共用了三個章節(jié)，分別介紹了太陽能的基礎知識，太陽熱系統(tǒng)，以及太陽能光伏系統(tǒng)。其他能源形式基本是每種一章。同時，《非傳統(tǒng)能源（第2版）》對儲能也給予了關注，除了有單獨的一章介紹儲能外，對風能等具體能源形式的儲存問題也進行了介紹?！　　斗莻鹘y(tǒng)能源（第2版）》的主要特色還有以下幾個方面：首先是有大量的例題，這在目前很多相關內(nèi)容的書籍中是比較少見的；大量的例題非常有利于對內(nèi)容的理解。其次是有很多特色習題，《非傳統(tǒng)能源（第2版）》的習題分為三部分，一是用來復習課本內(nèi)容的問題（Review Questions）；二是一些分析或計算題（Problems），可以對課本中的知識進行應用；三是客觀題（Objective Questions），主要是對一些基本的知識點進行考查?！　　斗莻鹘y(tǒng)能源（第2版）》所介紹的例子、應用情況均是以印度的情況為主，閱讀和使用時，建議盡量參考我國的實際情況進行修改和補充。

章節(jié)摘錄

插圖：The highest inlet steam temperature for a steam turbine is limited by theproperties of the materials to about 540~C. However, the flame temperaturesof burning fossil fuel in a boiler may be more than 1650~C. Consequently, in acombined cycle system, steam turbine is preceded by a topping cycle heat engine,which can utilize heat at higher temperatures. The working fluid leaves the toppingcycle at a sufficiently high temperature to generate steam for the steam turbine. Because the technology is well developed for the gas turbine, it is most commonlyused as a topping cycle engine. The turbine exhaust gases at a temperature of 600C or more pass through a waste heat （heat recovery steam generator） boilerwhere steam is produced from water under pressure. In addition to using fuelmore efficiently, a combined gas and steam turbine generating system requireslesser condenser cooling water for a given electrical output than a steam turbinegenerator alone.
