What is the function of a steam boiler? - Quora. Function of Steam Boiler. A boiler is defined as "a closed vessel in which water or other liquid is heated, steam or vapor is generated, steam is super heated, or any combination thereof, under pressure or vacuum, for use external to itself, by the direct application of energy from the combustion of fuels.
The larger the heating surface a boiler has, the more efficient it becomes. The boiler system is made up of: 1. Feed water system. 2. Steam system. 3. Fuel system. The feed water system provides water to the boiler and regulates it automatically to meet the steam demand. The water supplied to boiler that is converted to steam is called feed water.
The following boiler auxiliaries are required by the British Boiler Regulations: (1) safety valves, (2) water gauges, (3) boiler feed check valve, (4) blow-down valve, (5) low-water-level safety device, and (6) main stop valve. In a boiler, two safety valves must be provided, each capable of discharging the peak evaporation of the boiler.
Function: The function of a safety valve is to prevent excessive pressure from building up in a steam boiler. If the steam pressure in the boiler drum exceeds the working pressure, it permits the steam in the boiler to escape to the atmosphere until the safe working pressure in the boiler is reached again.
Basic Function of a Boiler. As the name states the function of a steam boiler is very simple i.e. generating, storing and distributing the steam. The fluid is contained in the boiler drum called shell and the thermal energy released during combustion of fuel is transferred to water and this converts water into steam at the desired temperature and pressure.
The function of the injector is same as the feed pump; it is used where space is not available for feed pump installation. In an injector, the Kinetic energy of steam is used to increase the pressure and velocity of feed water in a convergent-divergent nozzle.
The steam generated by the boiler can also be use for cleaning, and heating of the seawater in the freshwater generator thus evaporating it to make it potable water. There are two types of boiler mainly use in the Marine Industry, The water-tube boilers and the fire-tube boilers. The most common of which is the water-tube.
This article discusses about the different parts or components that are present in a boiler. In this article we will get to know about each every component that is fitted inside the boiler. For example, super heater is the part of boiler that is used to generate superheated steam. Let's discuss these parts in detail.
In a water tube boiler a separate superheater section can be built into the same 'box' as the boiler section. Steam Drum The steam drum serves two primary functions: 1) Separate the steam from the steam/water mixtures that return from the boiler. 2) Provide a holdup capacity of water to feed the boilers.
Steam boilers provide efficient heat for homes and industrial settings. In most cases, raw water is fed into the boiler from a pipe system. That water is then purified to clean it of any debris. Next, the water is fed into a de-aerator that removes air, then is fed into the boiler tank and heated.
