The water tube boilers are mainly used for generating steam with high temperature as well as pressure. The internal structure of this boiler includes a tiny steam drum, small width tubes. The components of this boiler generate high-volume vapor for high-capacity applications. These boilers are most frequently used boilers, which has replaced several boilers like fire tube due to some reasons like the weight of this tube is less, steam producing process is faster, custom design, high efficiency.

Difference Between Fire Tube Boiler and Water Tube Boiler [With PDF]

In the last session, we had discussed Lamont boiler , Benson boiler , Cochran boiler , Babcock and Wilcox boiler in a detailed way whereas, in today's session, we will discuss What is a Boiler?

Selection of a boiler, Essentials of Good boiler, Classification of a boiler, Diagram of the boiler, Boiler Mountings, and Boiler Accessories in a detailed way. The working principle of the boiler is very simple. For bathing, especially in winter, you need to heat water so you should not feel coolness around you. However, at home, you cannot collect the steam but in the industries, that steam is used to generate electricity.

The boiler is a closed vessel that stores the water in it. Apart from water, boiler mountings and boiler accessories are also present which increases the efficiency of the boiler which are explained below. The Fuel coal is generally used as a furnace to heat the water present in the boiler shell.

The hot gases from the furnace touch the surface of the boiler shell and thereby steam is generated inside the shell which on further operations can drive the turbine. The driving of the turbine leads to the generation of electricity which will be used for various purposes. The parts of a horizontal boiler can be inspected and repaired easily. But, it occupies more space and the vertical boiler occupies less floor area. The boilers which produce steam at pressures of 80 bar and above are called high-pressure boilers.

Portable or mobile boilers include the locomotive type and other small units for temporary usage at sites Just as in small coal-field pits. It is fitted on the boiler so that we can come to know, how much water level was present in the bolier such that suitable steam can be generated from it. The function of Blow off cock is to empty the boiler by removing water, mud and sediments which are collected at the bottom of the boiler shell.

The main function of Feed Check Valve is to regulate the supply of water which is pumped into the boiler by employing feed pump. They are generally used to avoid the exposion takes place inside the boiler shell due to the excess pressure. When the pressure crosses the critical pressure, then the safety valve opens which allows excess steam to escape into the atmosphere untill the pressure inside the shell reaches normal pressure.

The Pressure gauge used in the boiler is especially of Bourdan type which is used to measure the pressure inside the boiler shell. The fusible plug is placed at the top of the firebox whose duty is to avoid the explosion taking place due to the overheating of furnace when the water level in the boiler falls to an unsafe limit and it extinguish fire in the furnace.

A feed pump is one of the accessories of the boiler which is used to force the feed water into the boiler at high pressure. There are two types of Feed pumps,. This accessory of the boiler is used to separate the steam from the water in the boiler shell. If it is not taken, then an increase in furnace vaporizes the steam present in the boiler. It is used to heat the feed water coming out from the boiler before it leaves the chimney to the atmosphere so that, the heat from the flue gases can be used as a preheat to other elements.

It is placed or installed between the Economiser and Chimney and it has to supply preheated air into the furnace such that an increase in temperature takes place which accelerates the combustion of the fuel. The function of Superheater is to increase the temperature of the steam about the saturation temperature. It is also a device that is used to convert saturated steam into supersaturated steam.

This is the complete explanation of the Boiler. If you have any doubts feel free to ask in the comment section. The equipment used for producing steam is called Boiler or Steam Generator. Your email address will not be published. Notify me when new comments are added.

Apart from water, boiler mountings and boiler accessories are also present which increases the efficiency of the boiler which are explained below.

The main difference between fire tube and water tube boiler are, fire tube boiler are internally fired and water tube boiler are externally fired boiler. In short: If you understand these differences you can easily score maximum out of it either it may be an exam or Interview. A Boiler is a closed vessel in which steams are generated Water to steam with the help of coal-burning or other fuel substances. The fire-tube boiler is the boiler in which fire hot flue gases is inside the tube and water is surrounded by them. The Water-tube boiler is the boiler in which Water is inside the tube and fire hot flue gases is surrounded by them.

Water Tube Boiler – Working Principle, Types of Water Tube Boilers

Efficiency is stable as a result of a well-controlled excess air curve, due tothe geometry of the burner head and electronic cam modulation. The longitudinal stresses on the tube plates are therefore symmetrical. The expansion of the tubes is evenlydistributed over the whole diameter of the boiler.

Boiler tubes are expanded and flared in low pressure boilers; expanded and beaded in high pressure boilers. Turbulator baffles are not used in tubes. Separate second and third pass rear tube sheets allow safe expansion and contraction. Waterbacked rear turnaround promotes rapid internal circulation and reduces gas temperatures at entrance to.

One of the latest advances in steam production technology is the use of water tube boilers. This type of boiler is distinct from conventional boilers that use a fire tube system. Water tube boilers are more efficient than fire tube boilers, generating more steam but using less fuel.

Difference Between Water Tube Boiler And Fire Tube Boiler

fire tube boiler parts and functions pdf

Nice stuff..!! It was very nicely explained the difference between two boiler methods with the example of apple and orange i. Mostly it depends upon the people for which they mostly prefer. I didn't know that watertube and firetube boilers worked in such opposite ways to get the same result. It sounds like firetube systems are a little more complex in their design, but it's interesting to see the advantages of each system. If I need to rent a boiler with easy maintenance, I'll go with a firetube. But if I need something that is more durable, I'll go with watertube.

The main differences between the fire tube and the water tube boiler are the hot gases flow inside the tube and water surround them in the fire tube boiler whereas, In the water tube, water flows inside the tube and Hot gases surround them. Before moving to further detailed explanation lets have some overview of Fire tube and water tube boiler. Note: At the bottom of every article the PDF link is attached make sure if you want you can easily download. A boiler is a closed vessel in which fluid generally water is heated up to high-pressure steam. The boilers are used in power plants, for the generation of steam. They are mostly used in power plants where steam turbines are used for the generation of electricity.

Токуген Нуматака познакомился с Танкадо много лет. Молодой программист приходил когда-то в Нуматек, тогда он только что окончил колледж и искал работу, но Нуматака ему отказал. В том, что этот парень был блестящим программистом, сомнений не возникало, но другие обстоятельства тогда казались более важными. Хотя Япония переживала глубокие перемены, Нуматака оставался человеком старой закалки и жил в соответствии с кодексом менбоко - честь и репутация. Если он примет на работу калеку, его компания потеряет лицо.


Firetube boilers contain the combustion gases in straight tubes and the combustion chamber while the water and steam circulate outside these tubes. All of this is.

Там она и стала тем, кого японцы именуют хибакуся - человеком, подвергшимся облучению. Через девятнадцать лет, в возрасте тридцати шести лет, она лежала в родильном отделении больницы, страдая от внутреннего кровотечения, и знала, что умирает. Она не знала лишь того, что смерть избавит ее от еще большего ужаса: ее единственный ребенок родится калекой. Отец Энсея так ни разу и не взглянул на сына. Ошеломленный потерей жены и появлением на свет неполноценного, по словам медсестер, ребенка, которому скорее всего не удастся пережить ночь, он исчез из больницы и больше не вернулся. Энсея Танкадо отдали в приемную семью. Каждую ночь юный Танкадо смотрел на свои скрюченные пальцы, вцепившиеся в куклу Дарума note 1и клялся, что отомстит - отомстит стране, которая лишила его матери, а отца заставила бросить его на произвол судьбы.
