Unit Eight
Drax Coal-Fired Power Station
Steam Drum
The steam drum is an all welded cylindrical construction supported by two Uslings from the steelwork. The drum was manufactured in one piece at the factory and was transported to the site by sea. It has a length of 30.40 m and an internal diameter of
2.29 m. Its weight with the internal fittings is 335 t.
Four rows of 65 conical cyclone separators axe fitted in the drum and above each separator is an inclined primary scrubber. Secondary scrubbers are fitted at a higher levelclose to the saturated steam takeoffs. The drum is made from high tensile steel and nowelding is permitted on the drum after it has been stress relieved.
Apertures in a girth baffle allow the combined steam and water mixture to enter
cyclone separators which are arranged in pairs, in two rows along the front and the rear of the steam drum. The steam and water mixture enters each cyclone body tangentially and whirls around the inside of the cylinder producing a powerfull vortex, within which a positive separation of steam and water occurs. The steam collects in the centre and passes out at the top, whilst the water moves downward in a helical path and passes back into the drum water space for recireulation through the furnace walls. The saturated steam flows upwards through the primary inclined scrubbers which remove water residue that may be carried over by the steam after leaving the separator. The steam then passes through secondary scrubbers, fitted at the top of the drum, which provide a final separation of
water from the steam before it leaves the drum and flows into the superheating circuits. Draught System.
The draught system comprises two forced draught(FD) fans, two induced draught
(ID) fans, two rotary airheaters and three elect.w-static precipitators. Air for combustion is supplied to the bumer registers by the two FD fans by way of air preheaters where the boiler flue gases heat the incoming air. ……

书评(卓越)
序随着我国改革开放的深入和经济的发展,我国电力工业迅速发展,尤其是火电厂建设迈上了一个新台阶,引进机组和设备不断增加,对外交流日益频繁。广大火电厂建设、管理和运行的科技人员和工作人员以及相关专业的在校大、中专学生,迫切需要掌握英语这一对外交往的工具,学习先进技术,促进对外交流。
作为一所全国重点大学,武汉水利电力大学每年向国家输送大量电力建设专业人才。由于国家经济体制的进一步改革,电力工业无论在深度和广度上都发生了深刻的变化。因此,对人才素质的要求越来越高。为了适应这一变化,武汉水利电力大学以“211工程”为契机,深入教育改革,发展学科建设,充实、更新教学内容,推出了一批深受学生和社会好评的教材和教科书。
唐必光和谢诞梅等同志所编的这本《火电厂专业英语》教材,是他们在武汉水利电力大学任教期间,瞄准向火电厂培养“全能值班员”这一目标,根据学生、尤其是广大现场工作人员的实际要求,并结合自己的教学经验编写而成的。全书以锅炉、汽轮机和发电机三大主机为主线,广泛涉及大型机组(600 MW和300 MW)的结构、原理、运行和管理等内容,还包括火电厂的设计规划及厂址选择、自动控制、电厂化学及环境和招标等内容。特别值得一提的是,这本书还涉及诸如洁净煤技术、DEH控制系统、燃气一蒸汽联合循环技术、烟气脱硫技术、计算机控制等许多高新技术。全书内容新颖,专业词汇覆盖面广,生词重复率高。全书的内容编排不仅保持了火电厂专业知识的系统性,而且符合英语教学的特点。
因此,我很高兴地向广大读者推荐这本教材。希望并相信它对与火电厂有关的在校本专科学生、研究生和工程技术人员学习英语、并掌握当今技术发展能有所裨益。
