What are Boiler Accessories?
Devices and facilities that are installed with boilers to enhance their performance and overall efficiency are known as boiler accessories. These devices can either be positioned directly on the boiler or near the boiler and its surroundings.
These components are not essential to the boiler. So if they are not installed, the boiler can still function, albeit inefficiently.

Types of Boiler Accessories
The different types of boiler accessories include:
Steam Separator
Wet steam cannot be used in turbines; as a result, a steam separator, often referred to as a moisture separator, is employed. The steam separator's job is to take water vapor out of the steam. It is attached to the boiler's main steampipe. Water droplets in the steam limit thermal efficiency, so it is crucial to extract the steam from the water.
Water buildup inside the cylinder might result in a hydrostatic lock, which harms the engine. The turbine blades in thermal power plants are harmed by water droplets of high-speed steam from the nozzle. They are categorized as impact (or baffle)-type, reverse current-type, and centrifugal-type based on operating principles.

Air Preheater
Heat from the exhaust flue gasses is recovered using the air preheater. Between the chimney and the economizer, heat is established. Air used for combustion travels through the preheater. With the assistance of exhaust flue gasses, this raises the temperature of the combustion air.
Flue gas exits the heating tubes through their exterior while air exits through their interior. As a result, heat is transported from the flue gasses to the combustion-related air. 2.3 to 2.6 percent of fuel can be saved if the combustion air's temperature is raised to 1000 ℉ with the use of an air preheater. It is also possible to save 5 to 10 percent on fuel in specific circumstances.
Feed Pump
High-pressure water is fed into boilers using feed pumps. Because of the high steam pressure inside the boiler, it is necessary to raise the feed water pressure before it reaches the boiler in order to ensure smooth operation. The pressure in the feed water is typically 20% higher than the pressure in the boiler. The kind of feed pump can either be centrifugal or reciprocating.

Injector
Injectors serve the same purpose as feed pumps; they are utilized in situations when there is not enough room to install a feed pump. A converging-diverging nozzle's feed water is subjected to a rise in pressure and velocity thanks to the kinetic energy of steam in an injector.
Soot Blower
The furnace's inner tubes become covered in soot during burning, and the gas passes are blocked in. In the end, soot buildup inside the furnace lowers the boiler's effectiveness. To avoid the gas pass becoming clogged, soot is removed from the tubes using a soot blower.
Pressure-Reducing Valve
A pressure-reducing valve's job is to keep the pressure on the boiler's distribution side constant, independent of the pressure inside the boiler itself.
Superheater
Without increasing its pressure, the superheater boosts the temperature of saturated steam. It is made up of a compact collection of tubes. It is positioned in the furnace's hot flue gas route. Hot flue gasses exit the heater tubes while saturated steam is forced through them.
Thus, heat is transferred from hot flue gasses to saturated steam, raising its temperature without increasing steam pressure. Convection and radiation superheaters are employed for this purpose. The position of the superheater, the temperature of the hot flue gasses, the design of the superheater, and the steam flow all affect how hot the steam becomes.
Economizer
A heat exchange device called an economizer recovers some of the heat from exhaust (flue) gas and uses it to warm feed water. Economizer units are typically positioned between the boiler and the chimney.
Applications of Boiler Accessories
A number of industries use boilers as their main source of heat. They purify water, heat huge buildings or entire greenhouses, and produce electricity in power plants. The operation of an industrial boiler involves numerous accessories and parts. Some of these extras can be installed after installation, while others are incorporated into the unit itself.
