Structure Of Steam Boilers

Apr 29, 2016· Here working and construction details of water tube boiler is explained. Different parts of boiler such as economizer, super heater, re heater, water wall and steam drum are illustrated here.

Boilers can be classified into the following configurations: Pot boiler or Haycock boiler/Haystack boiler: A primitive "kettle" where a fire heats a partially filled water container from below. 18th century Haycock boilers generally produced and stored large volumes of very low-pressure steam, often hardly above that of the atmosphere.These could burn wood or most often, coal.

Jul 17, 2017· Although designs vary, a boiler has four main parts: the burner, the combustion chamber, the heat exchanger and the pluming apparatus. A boiler is a self-contained combustion system that heats water. The hot water or steam produced by a boiler is then used in heating systems.

The new-type structure steam boiler adopts single drum vertical type arrangement, and two sides of the furnace are arranged with water cooled wall. lexie@zozen.com > Get A Quote > Commercial Steam Boilers: A Primer …

Steam Production From steam tables we can see that the total heat of steam does not vary a great deal as the boiler pressure increase The boiling point (b.p.) increases as the pressure increases Thus the sensible heat increases as the pressure increases, and the latent heat decreases Boiler pressures are expressed in psia, psig, bar, kg/cm2

File Size: 258KB Dec 11, 2017· Fire tube boilers are useful for small demands of steam and water tube boilers are useful for industrial level usage. To cut short the main purpose of boiler is to boil a liquid mostly the water in order to generate the steam for serving the purpose of heating a building or running an equipment through pressurized steam or pressurized water.

Economizers and water wall sections are usually constructed with a mild or medium. carbon steel, whereas. low alloy ferritic steels are used for most super heater and re heater sections, with austenitic stainless steels specified for the highest -temperature circuits or corrosion. performance.

Oct 06, 2016· 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. Types of Steam Boilers. Fire Tube Boilers: Relatively small steam …

Aug 27, 2015· The support structure includes a support platform structure, comprising a part of the primary load bearing boiler cold structure for the boiler envelope, and adapted to engage with and thereby carry at least a major part of the static load of the boiler envelope.

The steam-generating facility, located in the boiler room, consists of boilers, feedwater systems, heat exchangers (e.g., economizers), boiler and system controls, fuel and gas handling equipment (e.g., fuel trains, stacks), and steam/water treatment equipment and piping (Figure 2).

The Basics and Origins of Steam Power Steam is water vapor, or more generally, the gaseous form of the molecule. Water consists of hydrogen and oxygen atoms and has a molecular formula of H 2 O.
