Finding the best boiler manufacturer that suits your business is a daunting task. You can come across thousands of manufacturers, including legit and fraudulent ones. The worst part is that you might not be able to catch them in time, wasting your time and hard-earned money. Furthermore, you need a boiler that best fits your industry requirements. Therefore, it is crucial to have a detailed product description and know the company’s background.
So, fasten your seatbelt as we guide you through the basics of boilers and discuss the most popular industrial boiler manufacturers worldwide. Let’s get started.
Fundamentals of Boilers: Working Principle and Classification
Let’s start with the working principle of a boiler, as it is the most important factor in knowing whether a boiler is right for you or not.
Working Principles of a Boiler
To put it simply, a boiler is a sealed container of water. This vessel is heated through the combustion of flue gases to produce hot water or steam.
The heat transfer between the water and the steam occurs in the water vessel. This water vessel is made to come into contact with these hot gases.
Hence, we can say the boiler’s main function is to use thermal energy to change water into steam.
The boilers come in a variety of designs and serve different functions. Hence, understanding the type of boiler your facility requires is important before deciding on a boiler manufacturer.
Classification of a boiler
A boiler can be classified into the following categories:
1. Relative Passage of Water and Hot Gases
- Water-tube boiler
- Fire-tube boiler
A boiler in which water runs through tubes that are encircled by hot combustion gases. Similarly, a boiler with a fire tube that has water surrounding the hot combustion gases.
2. Position of Boilers
3. Water Circulation Arrangement
- Natural Circulation
- Forced Circulation
Natural circulation occurs as a result of density differences. In comparison, forced circulation in a boiler occurs through a pump, creating circulation.
4. Pressure Generated by Steam
- Low-Pressure Boiler
- Medium-Pressure Boiler
- High-Pressure Boiler
A low-pressure boiler is a heating source with a maximum pressure of 15–20 bar. In a similar manner, a medium-pressure boiler produces heated steam or water with a maximum pressure of 20 to 80 bars. A high-pressure boiler produces more than 80 bars of maximum pressure.
- Sub-critical Boiler
- Supercritical Boiler
The sub-critical boiler produces steam at a pressure lower than the critical pressure. Similarly, a supercritical boiler creates steam at pressures higher than the critical pressure.
5. Charge in the Furnace
- Supercharged fuel
- Pulverized fuel
Now, let’s discuss the best industrial boiler manufacturers in the world and see what types of boilers they offer.

Key Boiler Components: Common Issues and Preventative Measures
Below are an industrial boiler’s components, issues, and possible solutions.
This is where the magic of heat generation occurs. The industrial burner is where fuel and air mix to produce the energy needed to heat water.
- Inefficient combustion can result in fuel waste.
- Blocked burners can lead to fuel leaks, which can cause explosions.
- Conduct regular inspections of the burner. This covers both electrical and mechanical connections.
- Ensure there are no fuel leaks.
- Routinely check for corrosion on the surface, fuel pipes, and other boiler fittings.
- Regularly inspect for any debris on the fuel source or the fresh air supply needed for combustion.
The combustion chamber is an enclosed space where combustion happens, producing energy and heat.
- The accumulation of soot and debris in the combustion chamber can reduce the boiler’s efficiency and cause fire hazards.
- Periodically clean the combustion chamber.
- Ensure that the air intake is appropriate.
- Inspect for cracks or corrosion on the materials lining the combustion chamber.
It’s where the heat generated through combustion is transferred to the water. In most boiler designs, it consists of tubes that carry fluids.
- The heat exchanger’s surface comes into contact with fluids of different temperatures. Hence, it can receive damages.
- Check for cracks or other changes in materials.
- Use methods like ultrasound and eddy current testing. This won’t harm the tubes.
Controls include switches, knobs, sensors, and other components. These components are responsible for regulating boiler operations.
- Electrical or advanced control components can experience problems, including electrical issues or outdated software.
- Inspect the electrical connections on control elements.
- Ensure that control systems use up-to-date software.
- Replace hardware components based on the schedule provided by the original equipment manufacturers (OEMs).
Transport lines, including pipes and tubes, convey boiler water, hot water, and steam within an industrial boiler system
- Cracks or leaks may develop in transport lines over time, reducing efficiency.
- Regularly examine transport lines for corrosion and cracks.
- Verify that there is no pressure loss within the pipes and tubes.
- Ensure there are no obstructions impeding fluid flow.
