The book discusses instrumentation and control in modern fossil fuel power plants, with an emphasis on selecting the most appropriate systems subject to constraints engineers have for their projects.

It provides all the plant process and design details, including specification sheets and standards currently followed in the plant. Spec sheets are included for each type of instrument. He has a number of national and international technical papers to his credit. Consistent with current professional practice in North America, Europe, and India. Chapter II. Some other subsystems are, namely, the regenerative heating cycle or offsite packages such as a water treatment plant demineralization and pretreatment , a coal-handling plant CHP , an ash-handling plant AHP , an oil-handling plant OHP , circulating water CW and auxiliary circulating water ACW systems, a condensate polishing unit CPU , and others.

A boiler is a combination of several items that is a means for combustion to provide energy to be transferred to water until it becomes heated steam that is then used for transferring the heat to the turbine.

Water is used as the working fluid to transfer the heat to a process because it is not expensive. As a result of the tremendous volume change after the water is converted to steam, it needs careful handling. The equipment needed for the fuel system depends on the type of fuel used in the system. The amount of fuel and air required for steam generation is automatically controlled per steam demand.

The type of mills and pulverizers depends on the type of fuels. Associated feeders and so forth are also a part of this subsystem. Fuel burners: This category covers both oil and solid fuel with various designs—for example. Burner type also varies with type of atomizer, etc. Draft system or flue gas system: These include induced draft ID air fans and various flue gas dampers for evacuating the product of combustion from the furnace. Soot blowing system: Periodic cleaning of soot buildup, which damages boiler metals and causes inefficient operation, on the radiant furnace surfaces, boiler tube banks, economizers, and air heaters is accomplished using a soot blowing system that blows hot steam on a regular basis.

Pressurized and preheated water supplied to the boiler as the working fluid to be converted into steam is popularly called feedwater in a normal running condition. Chemical dosing: This is done to clean the feedwater to avoid blowdown causing both heat and water loss making it slightly alkaline to minimize metal loss due to a chemical reaction.

Boiler circulating water system: In some plants, a boiler circulating water pump BCWP is deployed for better circulation of feedwater in the boiler with its suction connected to a steam drum and a discharge connected to a boiler water wall header. Furnace height may be reduced by having BCWP. The steam system includes evaporation of water up to superheating, reheating of cold steam for a hot reheat system , collection and transfer of the steam through a piping system to the turbine.

The turbine accepts steam from the boiler at a high temperature and pressure, and converts the heat energy into mechanical energy for driving the generator. The following are the associated subsystems:. This subsystem is one of the most important items; it supplies the lube oil to all the bearings, hydraulic control oil, jacking oil, and actuator power oil through individual oil coolers, strainers, redundant pumps, etc.

These subsystems are supplied to protect the boiler reheater from a burnout when no steam is passing through the turbine with the boiler generating steam during start up or running or tripped condition. These valves are provided for both high- and intermediate-pressure turbines. Both are hydraulically operated and are special valves with high controllability and isolating capability, respectively. Turbine glands are a part of the turbine so that steam cannot escape from the higher pressure parts of it and air cannot enter the lower parts of the turbine.

However, many parts of the turbine operate at such a high pressure that it cannot prevent leakage to the full extent.

On the other hand, the lower pressure parts operate at a subatmospheric region so air ingress cannot be totally eliminated. This subsystem is provided to seal the glands in such a way that leakage of steam from the high side is controlled at a certain pressure and extra steam from the control valve outlet is diverted to the low-pressure LP side glands to arrest air ingress by maintaining a certain pressure.

The function of condenser is to condense the steam coming from the turbine exhaust. High vacuum is maintained to extract steam and Erscheint lt. Verlag Wie bewerten Sie den Artikel?

Но, приближаясь к рубильнику, Стратмор понял, что ему необходимо преодолеть еще одно препятствие - тело Чатрукьяна на ребрах охлаждения генератора. Вырубить электропитание и снова его включить значило лишь вызвать повторное замыкание. Труп надо передвинуть. Стратмор медленно приближался к застывшему в гротескной лозе телу, не сводя с него глаз. Он схватил убитого за запястье; кожа была похожа на обгоревший пенопласт, тело полностью обезвожено.

Даже не взглянув на верхушку башни, Халохот бросился к лестнице. ГЛАВА 99 Фонтейн время от времени стучал кулаком по ладони другой руки, мерил шагами комнату для заседаний, то и дело посматривая на вращающиеся огни шифровалки. - Отключить. Черт побери, немедленно отключить. Мидж появилась в дверях со свежей распечаткой в руке. - Директор, Стратмору не удается отключить ТРАНСТЕКСТ. - Что?! - хором вскричали Бринкерхофф и Фонтейн.

 - Я только что говорила с Джаббой. Он сказал, что в прошлом году сам установил переключатель. Личный помощник директора отказывался верить ее словам. - Никогда не слышал об. - Никто не слышал. Это было сделано тайно. - Мидж, - сказал Бринкерхофф, - Джабба просто помешан на безопасности ТРАНСТЕКСТА.

Что, разумеется, было не. Каждое послание состояло из числа букв, равного полному квадрату, - шестнадцати, двадцати пяти, ста - в зависимости оттого, какой объем информации нужно было передать.

Фонтейн почти во всем полагался на Стратмора и верил в его план, в том числе и в достойную сожаления, но неизбежную необходимость устранять Энсея Танкадо и в переделку Цифровой крепости, - все это было правильно. Но одно не давало Фонтейну покоя - то, что Стратмор решил прибегнуть к услугам Халохота. Тот, конечно, был мастером своего дела, но наемник остается наемником.

Сьюзан глубоко вздохнула. - Да поможет нам Бог, - прошептала.  - Мы можем принять участие в аукционе.

Сьюзан решительно шагнула во тьму. ГЛАВА 87 Веспа выехала в тихий переулок Каретерра-де-Хуелва. Еще только начинало светать, но движение уже было довольно оживленным: молодые жители Севильи возвращались после ночных пляжных развлечений. Резко просигналив, пронесся мимо мини-автобус, до отказа забитый подростками. Мотоцикл Беккера показался рядом с ним детской игрушкой, выехавшей на автостраду.

Слава Богу, разрешено хоть. Стратмор требовал запретить всяческий доступ, но Фонтейн настоял на. - В шифровалке нет камер слежения? - удивился Бринкерхофф.
