Apr 17, 2014 · Steam Drum – The steam drum is the upper drum of a water-tube boiler where the steam separates from the liquid water. The lower drum is referred to as the mud drum and it contains the liquid water. Boiler Tubes – The boiler tubes are the tubes through which the steam passes as it makes its way through the boiler. High strength carbon steel is often used in the fabrication of boiler tubes to make it more durable and to resist problems associated with corrosion or mineral deposits.
The major components of a high-pressure water tube power boiler are the furnace, which is the area of the boiler where combustion of the fuel takes place. The steam drum is the upper header to which the tubes are connected. Water enters through this drum, and steam generated in the boiler is collected there.
generation plants is the boiler pressure components. Boiler pressure component failures have historically contributed to the highest percentage of lost availability. Failures have been related to poor original design, fabrication practices, fuel changes, operation, maintenance, and cycle chemistry.

Water-tube boilers are boilers in which the water is contained in generating tubes and hot combustion gases flow around the tubes to heat them. Propulsion boilers are of this type. Fire-tube boilers channel combustion gases through tubes which are surrounded by water. Some auxiliary boilers are of this type.
A boiler is an enclosed vessel in which water is heated and circulated, either as hot water or steam, to produce a source for either heat or power. A central heating plant may have one or more boilers that use gas, oil, or coal as fuel. The steam generated is used to heat buildings, provide hot water, and provide steam for cleaning, sterilizing,
The trays are placed in each drum of a water tube boiler, or on the top flues of a fire-tube unit. All manholes, handholes, vents, and connections are blanked and tightly closed. The boiler should be opened every month for inspection of the desiccant. If necessary, the desiccant should be renewed. Wet Storage
Major Components of Boilers | Power Plant Technology. Major components of boilers include an economizer, superheaters, reheaters, and spray attemperators. Economizer. The economizer is the section of the boiler tubes where feedwater is first introduced into the boiler and where fl ue gas is used to raise the temperature of the water. Get a quote
Marine boilers are of two types namely the water tube boiler and the fire tube boiler. The water tube type boiler is used for high-pressure, high-temperature, high-capacity applications. The Main boiler design depends on its application, ie. for motor ships, a small fire tube boiler would be satisfactory.
Oct 26, 2017 · A water tube boiler is typically used in commercial and industrial applications, and not seen often in residential. As the name implies, the tubes contain the water being heated, and are surrounded by the hot combustion gases.
The main components of the boiler system include the feedwater heaters, deaerators, feed pumps, economizers, superheaters, condenser and condensate pumps. In addition, there are sets of controls to monitor water and steam flow, fuel flow, and chemical composition of the air and steam.
In water wall tubes, water flows and takes away the heat surrounding it. Thus the heat inside the boiler does not get transmitted to the outside of the boiler. These are of three designs namely: water cooled with refractory covered studded tubes; Close pitched exposed tubes and membrane Wall.
Tube failures are classified as in-service failures in boilers. These failures can be grouped under six major causes: Stress rupture; Fatigue; Water side corrosion; Erosion; Fire side corrosion (Called also as High temperature Corrosion) Lack of quality control. These lead to twenty-two primary causes that can cause a tube failure in a high pressure boiler:

Water tube boiler parts and their functions Steam drum. Mud or Water Drum. Water walls. Super heater. Economizer. Air Heater. Boiler Fans.
Water-tube boiler. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam .
Mar 16, 2016 · Babcock and Wilcox is a stationary water tube boiler. It has inclined tubes which are inclined at 10 to 15 degree, which are inclined to maintain natural circulation of water from drum to tubes and steam from tubes to drum. The main parts of this boiler are as follow.
For water tube boilers gas air heaters are only considered where the temperature at inlet to economiser is greater than 200 o C. Due to greater heat transfer efficiency between gas/water economisers are preferred to gas/air exchangers. Types of air heaters. Lungstrom gas/air heater (regenerative)
Knowing the water/steam flow through the boiler is critical to understanding the interrelationships of the boiler components. A summary follows: The flow begins when feedwater enters the economizer inlet header and flows through the economizer tubes to the outlet header picking up approximately 100-200 F of sensible heat to about 350 F.

And in this article we will discuss what are the boiler system's major components and their functions. water tube gas fired boiler. Feedwater Heaters. Feedwater heaters are energy recovery devices generally found only in large steam generating plants where all of the steam generated is not reduced to condensate by the steam user. This "waste steam" is reduced to condensate for return to the boiler in the feedwater heater.
The fire-tube boiler developed as the third of the four major historical types of boilers: low-pressure tank or "haystack" boilers, flued boilers with one or two large flues, fire-tube boilers with many small tubes, and high-pressure water-tube boilers. Their advantage over flued boilers with a single large flue is that the many small tubes offer far greater heating surface area for the same overall boiler volume.

Fire-tube boilers rely on hot gases circulating through the boiler inside tubes that are submerged in water (Figure 9.2.1). These gases usually make several passes through these tubes, thereby transferring
Dec 21, 2017 · Boilers can be basically classified into water tube boilers, fire tube boilers, packaged boilers, fluidized bed combustion boiler (FBC), Pulverized fuel boiler and waste heat boilers. In water tube boilers, the water to be heated flows in the tubes and the combustion gases flows around the tubes, thus converting the water into steam.
Natural water circulation, also referred to as “thermo-siphoning” is the major working principle for almost all water-tube boilers. This principle is illustrated via the diagram  shown below.
