(B)OILER

 

A boiler is a closed vessel  in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, Including water heating, central heating, boiler-based power generation, cooking, and sanitation.

 

      Industrial boilers are closed vessels requiring a fuel source or electricity in order to heat water or producing steam regarding industrial heating and humidification applications.

Industrial boiler imparts heat and power for a variety of systems and applications in several industries. Listed below some common industries & applications of steam boilers.

§  Turbines

§  Cement Production

§  Kilns

§  Sugar industries

§  Paper industries

§  Pulp industries

§   Diaries

§  Agriculture Soil Steaming

§  Ceramic material testing

§  Food processing industry

§  Rubber Industry

The motto of industrial boilers using in industries is doing a variety of things such as paper

and pulp, metalworking, refining, electrical, and refining and food and beverage.

Types of Steam Boilers

Talking about the basic concept of a boiler, it needs a heat source and a heat exchanger/heat    transfer medium allowing water to be heated more than its boiling point

Moreover, the type of heat source and the method of heat exchange are considered different

types of steam boilers.

Industrial boilers come of different types. Moreover, you can choose on the basis of different

aspects such as function, technology, heat, and source

 Boiler Types Based on Design

You may not find it a bit bizarre but true that boilers can also be distinguished based on boiler

design and construction.

v Vertical return tubular(VRT) are used in order to add hot gases from the heating source through

tubes attached inside a water-filled drum so that heat could be transformed into the

water.

v  Horizontal return tubular (HRT)boilers are generally held horizontal shape having self contained  fire-tubes along with a separate combustion chamber.

Apart from it, there are Scotch, Scotch marine and Firebox boilers on the list having all sorts of

features.

      Types of Boiler Based on Function

v  Hot water boilers are used to heat water for hydronic, which are needed for domestic,

and commercial both uses. It could be needed for various purposes such as

o   Freeze Protection,

o   Commercial Dishwashers,

o   Radiant Floor Heating,

o   Hot Water Needs,

o   Comfort Heating,

o   Car Washes,

v  Steam boilers heat hot water is required for producing steam to accomplish various job

applications such as

o   Turbines For Power Generation,

o   Various Industrial Heating Applications

o   Agricultural soil steaming.

      Steam Boilers types based on Combustion Technology

These combustion technology-oriented boilers have been designed going with the

technology emphasizing on the way of using burn or heat a specific fuel source They are designed in the way to maximize the entire performance. They are many types

available going with combustion technology such as

o    Fluidized Bed

o   Stoker

o   Spreader

o   Travelling-grate or chain-grate

o   Thermic fluid heaters

 Types Of Boilers Based on Heat Source

Talking about other sources, there are some other key aspects that differentiates boilers is the

heat source used. There are different types of heat sources used to have incredible job

application such

o   Gas Boilers

o   Oil Boilers

o   Husk Fired Boilers

o   Water Tube Boilers

o   Electric Boilers

o   High-Efficiency Boilers

o   Waste Heat Boilers

o   Biomass Boilers.

v  Coal – This kind of boiler is used for different types of job applications related to

industry and that is why it is called industrial boilers. Generally, pulverized coal which is

coal ground to a fine powder is used for it. The best thing is that that this coal type is

used more than larger clumps of coal.

v  Biomass– Next one on the list is fuel categorized to all sorts of burnable organic

material such as

o   Rice Husk,

o   Wood Chips,

o   And Other Agricultural Waste Products.

v  Gas- This one category is actually belonging to operating on the basis of using either

natural gas or propane.

v  Oil-These boilers do work on the basis of oil fuel sources such as gasoline or other

petroleum-based fluids.

v  Hydronic– These boilers are used going with steam considering as the heat source. In

these boilers, heat is transferred from the steam

v  Wood – Itis a fuel source used that goes with traditional boiler designs. It is used for

various purposes.
