Steam-Water Circulation in Boilers,generated in a large vessel. The vessel was heated from outside, which would create a convective current within the large body of water. This process did not pose any threat to the safety of the boiler. So a detailed knowledge of steam—water circulation or flow pattern was not important. Modern wate

Corrosion and Fouling of Heat Transfer Surfaces,ave been ranked as the number one equipment problems in fossil fuel fired power generating plants in the USA. Equivalent unavailability factor owing to tube failure for plants larger than 200 MW capacities was 2.7%. (DOE. 1998). Leading causes of boiler tube failures in the USA arranged in order of

Erosion Prevention in Boilers,s common in many industrial devices, including boilers. The combustion products of coal contain fly ash particles, which impinge on boiler tubes or fan blades and erode them. Fly ash erosion is the second most important cause for boiler tube failure (DOE, 1998). Tube failures by erosion in some case

Pressure Drop in Gas and Air Ducts, early days, gas passages in boilers were large. As a result the pressure drop owing to the flow of fluids through these passages was small. So most boilers did not need any external means for moving the fluid through the system. As with an open fire, air was driven through the fuel grate and the bo

Mechanical Design of Pressure Parts,here as.Tubes, drum, and headers are examples of pressure parts. Other components likes burners, etc., are not subjected to such internal pressure. As such they are classified as nonpressure parts. Selection of materials for pressure parts of a boiler and their mechanical design and construction are

Different types of boilers have different requirements as to the characteristics (size and moisture content, etc.) of the fuel fed into the furnace. Thus there is a variety of coal preparation systems.
