Steam Boiler | Working principle and Types of Boiler

Boiler or more specifically steam boiler is an essential part of thermal power plant. Definition of BoilerSteam boiler or simply a boiler is basically a closed vessel into which water is heated until the water is converted into steam at required pressure.

The Boiler Circulatory System: Beyond

The steam drum is 6.5 ft in diameter and collects and distributes the water/steam as it continuously circulates throughout the boiler. Once the water/steam enters the drum from the economizer outlet header via the economizer connecting pipe, it is forced by gravity down pipes called downcomers.

Boiler Drum Level Control

The boiler drum level control is the way in which a boiler water and steam levels are monitored and controlled.

Steam/water circulation design

water/steam mixture. The riser tubes forms the evaporator unit in the boiler. After risers, the water/steam mixture goes back to the steam drum. In the steam drum water and steam are separated: the saturated water will return to the downcomer tubes and the saturated steam will continue to the superheater tubes.

Boiler Inspections

Bi-drum and Single Drum Boilers

Bi-drum boilers find its use in industrial steam generators very widely as they are capable of handling lot of load fluctuations. This is mainly due to the reason that the water reserve available is very high when compared to single drum.

Chapter 14 Boilers

Boilers 293 Drums The drums that comprise a water tube boiler resemble a large water distribution header connected by a complex network of tubes. The mud drum is the lower drum in a boiler. The steam drum is the upper drum of a boiler where all of the generated steam is collected.

Dynamic Shrink/Swell and Boiler Level Control

The result is that the level in the steam drum above the combustion chamber rises. However, this rise in level is actually an inverse response to the load change. Since, the net steam draw rate has gone up, the net flow of water to the boiler needs to increase, because the total mass of water in the boiler is falling.

Package Boilers

Our elevated-drum design is used for drum retention times of 5 minutes or more from normal water level to low water fuel cutout. Additionally, this design is utilized where shipping limitations exist as it allows for a more symmetrical load with the upper steam drum shipped separately from the boiler and installed onsite.

Three-drum boiler

Development of the three-drum boiler began in the late 19th century, with the demand from naval ships that required high power and a compact boiler. The move to water-tube boilers had already begun, with designs such as the Babcock & Wilcox or the Belleville. The three-drum arrangement was lighter and more compact for the same power.

Water Tube Boilers

The following layouts work on the same principles as other water-tube boilers, and are available with capacities from 5 000 kg/h to 180 000 kg/h. Longitudinal drum boiler. The longitudinal drum boiler was the original type of water-tube boiler that operated on the thermo-siphon principle (see Figure 3.3.5).
