EPCB Boiler is the leading industrial boiler manufacturer and supplier who offers complete line of boiler system for various industrial applications. In this blog, let’s delve into different types of industrial boilers and there applications. You will need to know how to classify boiler and their use, and it will help you for right boiler selection.

1.What Is A Industrial Boiler?

An industrial boiler is a specialized device that plays a crucial role in various industries by generating high-pressure or low-pressure steam and hot water. It serves two primary purposes: providing heat for space heating and supplying energy for various industrial manufacturing processes.
Industrial boilers are designed with different types to cater to specific applications and operational needs, ensuring optimal performance and efficiency. They can be fueled by various sources, including natural gas, oil, coal, biomass, or electricity, depending on the availability and suitability of the energy source.
Each type of industrial boiler operates with different minimum water levels and varying levels of energy efficiency, allowing for flexibility and customization based on specific requirements. These boilers are vital components in industrial settings, delivering reliable and controlled heat and energy to support a wide range of manufacturing processes and space heating needs.

2. How To Classify Types Industrial Boilers?

2.1 Industrial Boiler Types According to tubing methods

Industrial boilers can be classified according to the flow of water and hot gases, There are two major types of boilers Fire tube boilers and water tube boilers.

Fire tube boilers are those boilers in which fire or flue gases are inside of the tubes and water is on the shell side. Fire Tube Boilers are low capacity low-pressure boilers usually used for heating, and processors to produce hot water.

The arrangement of the water tube boiler is that the water is contained inside the tubes while the hot combustion gas flows on the other side of the tubes. water tube boilers produce high-pressure steam which is used for power generation purposes. water tube boilers are more efficient and less dangerous than fire tube boilers. Mostly Fire tube boilers are Package type boilers that produce less amount and less pressure of steam than water tube boilers.

2.2 Boiler Types According to the type of Fuel Used or Fuel-Burning Methods

Boiler types can be categorized based on the type of fuel used or the fuel-burning methods employed. These include:

(a) Coal-fired boilers: These boilers utilize coal as the primary fuel source for combustion.

(b) Oil-fired boilers: These boilers burn oil, such as diesel or heavy fuel oil, to generate heat.

(c) Gas-fired boilers: These boilers use natural gas or liquefied petroleum gas (LPG) as the fuel source.

(d) Biomass boilers: Biomass boilers burn organic materials like wood pellets, agricultural waste, or dedicated energy crops to produce heat.

(e) Electric boilers: Electric boilers rely on electricity as the energy source to generate heat.

(f) Circulating Fluidized Bed Boiler (FBC Boiler): FBC boilers utilize a bed of suspended particles to combust fuels such as coal or biomass, providing efficient combustion and pollutant control.

(g) Pulverized Coal Boiler (PC Boiler): PC boilers grind coal into fine particles before combustion, achieving high combustion efficiency.

(h) Waste Heat Recovery Boilers: These boilers recover and utilize waste heat from industrial processes to generate steam or hot water.

(I) Nuclear Steam Generators: Nuclear steam generators utilize nuclear energy to produce steam for various applications.

These different types of boilers offer diverse options for industries to choose from, allowing them to select the most suitable and efficient boiler for their specific needs.

2.3 Boiler Types According To Steam Pressure

(a) Low-pressure Boilers

(b) Medium Pressure Boilers

(c) High-Pressure boilers.

According to ASME there every boiler have a pressure above 15 PSI is called a high-pressure boiler. but generally, Low-pressure boilers have pressure below 300 psi  (Bulk Boiling). Medium pressure Boilers have a pressure range between 300 psi to 800 psi (mixed Nucleate or bulk Boiling). Boilers having Pressure above 800 psi (film Boiling) are called High-pressure Boilers.

2.4 According to The Use of Steam

Process boilers, Utility boilers, and Marine boilers are examples of these types of boilers.

If the steam is used for process the is called a process boiler. Utility boilers are used to generate electricity in power plants they are usually water tube type boilers.

2.5 According to The Boiler Application

(a) Stationary

(b) Mobile, (Marine, Locomotive).

Stationary and portable boilers, there are some boilers that are not stationary like Locomotive Boilers and Marine boilers.

2.6 According to The Furnace Position

Externally fired boilers and internally fired boilers. Some boilers have their furnace outside the boiler are called externally fired boilers. In internally fired boilers the grate combustion chamber is enclosed within the boiler shell whereas in the case of extremely fired boilers and furnace and grate are separated from the boiler shell.

External Furnace

(a) Horizontal return tubular

(b) Short firebox

(c) Compact

Internal Furnace

Horizontal Tubular

(a) Short firebox

(b) Locomotive

(c) Compact

(d) Scotch.

Vertical Tubular

(a) Straight vertical shell, vertical tube

(b) Cochran (vertical shell) horizontal tube.

2.7 According to The Position of The Principal Axis 

(a) Vertical

(b) Horizontal

(c) Inclined.

Vertical and horizontal boilers. An example of a vertical boiler is the simple vertical boiler, Cochran boiler. Horizontal boilers are Cornish boiler, Lancashire boiler, and Locomotive Boiler

2.7 According To The Mumber of Tubes in Boilers

Single tube and multi-tube boilers. Single tube boilers like Cornish boiler and simple vertical boiler. These boilers have very low efficiency.

2.9 According to The Circulation of Water And Steam in Boilers

(a) Natural circulation

(b) Forced circulation.

Boilers are also classified as Natural circulation boilers and forced circulation boilers. The natural circulation limit is 140 Kg/cm2 above this pressure forced circulation is adopted.

2.10 According to the name of Boiler Manufacturer or Supplier

Some companies make boilers like Babcock and Wilcox boilers and Cochran boilers. These boilers are famous for their brand names.

Water-tube boilers are usually classified as follows :

Horizontal Straight Tube Boilers

(a) Longitudinal drum

(b) Cross-drum.

Bent Tube Boilers

(a) Two drum

(b) Three drum

(c) Low head three drum

(d) Four drums.

Cyclone Fired Boilers

Cyclone furnace technology to burn coal grades that are not well-suited for pulverized coal combustion. The ash from these coals has a very low melting temperature. This molten ash would normally be deposited on all downstream heat transfer surfaces, causing severe slagging and fouling. Cyclone-fired boilers are known for their high efficiency and ability to burn a wide range of fuels, including coal, biomass, and waste materials. They are commonly used in power plants and industrial facilities.
