Steam Boilers: What to Choose and Why?

Steam boilers: what to choose and why?

Steam boilers are mechanical devices used to generate energy in the form of steam. The whole process is quite explainable.

Steam boilers are pressure vessels that transfer heat to water to create steam. How do steam boilers work? What is its application and what types of steam boilers are there?

This article is all about providing logical answers to the above question.

How do steam boilers work?

The steam boiler works by transferring heat to water to produce steam. The water is heated to a suitable temperature under high pressure.

First, the fuel is brought to a high temperature in a furnace. Fuel can be natural gas, low pressure propane or coal, etc. The stove does its job by carrying out the combustion process.

The gases produced during the combustion process then flow towards the water and gradually increase the water temperature.

When the water is boiled to the optimal temperature, water is converted into high temperature and high pressure steam.

The steam is then consumed for various activities, from the industrial level to your HVAC system at home.

This whole process is carried out in a metal chamber of the boiler. To get a clean nack off the boilers Check product details.

The process mentioned above is the primary process used to create steam in a boiler. However, the way boilers work can differ from type to type.

For example, flame tube boilers work differently than water tube boilers. In flame tube boilers, the metal tubes contain the combustion gases and these tubes are surrounded by a vessel with water. Steam is generated when the temperature of the pipe increases.

In contrast, water-tube boilers contain multiple tubes in which water is present. Steam is generated here when the combustion gases outside the pipes become hot.

Let’s shed a little more light on these two most common steam boilers.

Flame tube boiler

As the name suggests, fire tube boilers work by bubbling hot gases through metal pipes. The container with water around the pipes gets hot to the boiling point and generates steam.

Burning tube boilers are owned by the first locomotive. These boilers are best used in small power plants because the steam generation rate is lower than with water tube boilers. Fire tube boilers do not require a high level of knowledge to work efficiently and economically.

Fire tube boilers are also superior to water tube boilers when it comes to the explosion.

They are less explosive than water pipes because the pressure is low compared to water pipe boilers. The operating pressure of flame tube boilers is approx. 25 bar.

A fire tube boiler is well known for generating steam. However, their enormous size and some inherent inefficiencies require a much more advanced boiler to handle complex steam generating tasks on an industrial scale. And modern water tube boilers were introduced.

Water tube boiler

Water tube boilers differ from flame tube boilers. These closed vessels function through the water flowing in the pipes, and the fuel gases surround the pipes. The gases are heated at high temperature and pressure, eventually boiling the water to create steam.

Water tube boilers are better able to generate steam at high speeds than flame tube boilers.

This makes them the main component of large industries and large power plants. Water tube boilers are more advanced than fire tube boilers and require much more attention to produce economical and efficient results.

Water tube boilers can generate steam with an unbelievable pressure of over 125 bar !!. That is five times the boiler. However, there is also a risk of explosion if not handled carefully.

Use of steam boilers

  • Steam is used for agriculture. The agricultural implements are disinfected with the help of steam. In addition to this, it is also valuable for soil sanitizing to get rid of the unwanted organisms in the soil.
  • Steam is also used to make cement in large-scale industries. In addition, steam boilers are required in oil refineries and other large power plants to perform complex tasks.
  • Steam also plays a vital role in your HVAC systems to serve water heating, cooking purposes, and more.


Steam boilers have gone through different stages. They have become the emblem for the start of locomotive train engines.

The dairy products like groceries, breweries, cement and much more are made with steam.

Steam boiler manufacturers should focus on building high quality steam generators with safety precautions.

And it is the responsibility of the industry owner to always put quality before quantity when buying steam boilers, as a risk of explosion for lack of knowledge constantly haunts them. For more information, see Yongxing China boiler manufacturer
