Yarrow boilers are an important class of high-pressure water-tube boilers. They were developed by Yarrow & Co. (London), Shipbuilders and Engineers and were widely used on ships, particularly warships.

The bent tube or Stirling boiler allows for a large surface heat transfer area, as well as promoting natural water circulation. Advantages of water-tube boilers: They have a small water content, and therefore respond rapidly to load change and heat input.

cross-tube boiler : usually a vertical flued boiler with a small number of large water-carrying cross-tubes within the firebox. The term is also applied to vertical boilers with other arrangements of tubes, such as those with horizontal fire-tubes.

  • Overview05-06-2018· In Water-tube boilers water passes through tubes and hot flue gasses surround them. 2: These are operated at low pressures up to 20 bar. The working pressure is high enough, up to 250 bar in super critical boilers. 3: The rate of steam generation and quality of steam are very low, therefore, not suitable for power generation. The rate of steam generation and quality of steam are better and …

Mud or water drum the lower drum is directly attached to upper steam drum with large no of straight tubes bundles called boiler bank tubes. Solids and mud can settle in this mud drum for removal through periodic blowdown. Some times desuperheater coil also installed in this drum to recover heat from superheated steam.

· PDF fileTubes and drums of water-tube boilers are smaller than that of fire-tube boilers and due to smaller size of drum higher pressure can be used easily. Water-tube boilers require lesser floor space.

When discussing steam boilers, there are two distinct types of large water content boilers, water tube and firetube. Water tube boilers are designed with water inside the tubes of the boiler and hot gases surrounding the tubes.

04-03-2020· There are many advantages of water tube boiler due to which these types of boiler are essentially used in large thermal power station. Larger heating surface can be achieved by using more numbers of water tubes.
