The water boiler is the perfect answer to your energy needs. Whether you require it for commercial or industrial use, it will not disappoint you. The boilers can work at high and low pressure according to your need. Following is all the information you might need to know before buying an industrial hot water boiler.

What Is The Definition Of An Industrial Hot Water Boiler?

An industrial hot water boiler is a heating device that converts mechanical energy into thermal energy. Boilers generate hot steam and deliver thermal energy to the whole plant or factory. Industries use these boilers to meet their heating requirements and several other purposes. It generates quality steam economically used by enterprises and power plants worldwide.

The industrial hot water boiler is a big metal container with two basic functions. They are; heating water and transforming it into high-temperature steam. Various heating applications use boilers for generating steam in order to function. You can think of it as a pressure cooker concept applied on a bigger scale.

Boilers have to withstand high temperatures and high pressures. Therefore, they are mostly welded from thick metal plates. Due to their durability needs, they usually weigh more than 150 tons.

Moreover, the industrial hot water boilers have a reversing chamber. It redirects the flue gases back into the secondary and third smoke tubes. As a result, it allows for a maximum heat transfer rate.

What Are The Main Components Of An Industrial hot water boiler?

An industrial hot water boiler has the following components:


The burner is the part of the boiler that mixes air and fuel for efficient combustion. It is also responsible for starting the combustion process. The burner receives an electronic signal from the thermostat and ignites the fuel. It has a forced draft along with fuel atomization. On the other hand, gas burners use either forced or natural draft.

Boiler Furnace

A boiler furnace, also called a combustion chamber, is where the actual combustion of fuel happens. The furnace is usually made up of cast iron to cope with high temperatures and pressures. The combustion process can occur using various fuels such as gas, oil, biomass, or wood.

Combustion needs three things to happen: fuel, oxygen, and heat. By controlling them, you can control the industrial hot water boiler operation efficiently. Oxygen is an essential ingredient needed for combustion. Less air (oxygen) can stop the fuel burning. It can cause pollution by producing carbon monoxide and waste fuel. Moreover, the rate of fuel fed to the furnace also counts. It changes according to the boiler temperature.

Heat Exchanger

The combustion process creates hot gases that give off heat. The heat produced goes to the feed water through the heat exchanger’s internal piping. As a result, the liquid warms up, and the gases cool down. The heat exchanger carries the heat to the water without any direct contact using convection and radiation.

In a water tube boiler, the gases move through the metallic tube walls of the exchanger. In comparison, the gases in a fire tube boiler move inside the tube, heating the water in the drum.


This component is responsible for starting and shutting down the process. According to the fluid temperature, the aquastat signals the burner to either start or end the operation.

Expansion tanks

The expansion tank protects the industrial hot water boiler from high pressures. It makes sure that the boiler is safe during the operation. When the water heats, it rises and increases the pressure. If the pressure rises too much, it can be harmful. The air in the expansion tank absorbs it to counteract the high pressure. Due to this, the pressure remains stable.

Supply and Return Lines

Supply lines in an industrial hot water boiler distribute the heated steam to different parts of the boiler, such as radiators. When the water or steam at the parts cools down, they go back through return lines. They are then reheated and go again by supply lines.


How Does An Industrial hot water boiler Work?

The working principle of an industrial hot water boiler is quite simple. It occurs in the following steps:

Fuel Feeding

A hot water steam boiler requires fuel to run. The boiler can use different types of fuels such as coal, oil, and gas. Firstly, the fuel moves into the furnace. You can feed the fuel either yourself or using an automatic fuel feeding machine.


The combustion relies on the aquastat’s signal. After it signals, the burner ignites the fuel, and the combustion starts. The temperature inside the chamber gradually rises. Fuel burns at high temperatures and gives off hot flue gases. Eventually, the hot flue gases rise due to their low density.

Steam Generation

The hot flue gases generated in the combustion chamber move towards the water tubes. There, heat transfer takes place. The water is in either tubes or a large drum. It absorbs the heat from the gases and heats up. Eventually, water transforms into steam. The steam is then ready to use.

Heat Economizer

After the transformation of steam, flue gases have a little heat remaining. These gases move into a heat economizer. The heat economizer heats the feedwater by the used flues gases. In this way, the water is already a little heated up before entering the boiler. Therefore, it takes comparable less energy to turn into steam. Thus, there is no heat loss, and efficiency is high.

Waste Removal

The combustion process always ends in the formation of ash. Fly ash is the ash that rises with the gases. It goes into the fly ash hopper by using the process of electrostatics. Another type of ash in the bottom ash that settles down on the chamber’s surface. It falls into the bottom ash hopper, where it is ready for recycling.

What Are The Different Types Of Industrial Hot Water Boilers?

There are two types of industrial hot water boilers according to their design. They are:

Fire Tube Boiler

In a fire tube boiler, the flue gases move through tubes. The tubes and the water are in the same big container. They have a very simple design and require less maintenance. These boilers have low costs and low efficiency of about 80%. Load fluctuation is also tricky for them. Plus, the fire tube boilers are not appropriate for low pressures. Therefore, they are used in small industries.

Fire-tube boilers have two, three, or four combustion gas passes. The gas first passes through a tube of large diameter. Then they take two, three, or four 180-degree turns and pass through smaller tubes than the previous pass. If the industrial hot water boiler has an even number of passes, it has a flue connection at the front of the boiler. If there are an odd number of passes, then the flue connection is at the back end.

Water Tube Boiler

A water tube boiler has such a design that the water is in the tubes. This type of industrial hot water boiler generates steam at high and low pressures. The water tube boiler has several water tubes in the vessel. The flue gases circulate in the same vessel.

The water tube boilers are more efficient than fire tube boilers as they have a high heat transfer rate. There is a conventional flow of water and steam in the boiler. Moreover, they are very safe and easy to operate. Mostly, they are used in large industries due to their higher efficiency.

The industrial hot water boilers are also classified according to the type of fuel they use:

Coal Fired Industrial Hot Water Boilers

A coal industrial hot water boiler uses coal to generate flue gases. Coal has cheap rates and is readily available. That’s why they are widely used for energy purposes. The burning of solid fuels such as coal forms coal powder and toxic gases. The coal boilers are simple and reliable. However, the carbon emissions are high, which means they are very harmful to the environment.

Oil Fired Industrial Hot Water Boilers

This type of boiler burns oil to get thermal energy. The oil industrial hot water boiler is an efficient alternative to natural gas if you live in an isolated place. Also, oil is easy to get than other types of fuels. These boilers also recycle the gases produced. However, they are big and require a large space. They are a little expensive and are externally installed.

Gas Fired Industrial Hot Water Boilers

Gas industrial hot water boilers burn gas to generate steam. They can use either natural gas or propane. However, propane boilers are more efficient. The gas boilers replace other boilers due to their safe and economical operation. They are small in size because they do not need any tank to store the fuel as the gas comes directly from gas lines. Moreover, they are not very harmful to the environment.

What Are The Various Devices Installed On The Boiler For Their Safety?

The industrial hot water boiler has mounting devices that ensure its secure operation. These devices prevent boiler malfunction and alarms if anything goes wrong. Following are the various boiler safety devices:

  1. Safety valve: It relieves the internal pressure in case system failure occurs
  2. Water level alarm: It alarms if the water level is too high or too low
  3. Pressure gauge: It tells the pressure of the boiler. If the needle is at 1 or 2, then it is safe. Otherwise, the pressure is too high or too low.
  4. Flame failure alarm: It alarms about ignition failure
  5. Smoke density alarm: It tells if the smoke is black and harmful by measuring its density
  6. Vent Valve: It avoids imploding of the boiler with high pressure by releasing the air out of the system
  7. Feed check valve: It controls the water flow into the boiler from the feed pump
  8. Water level indicators: It shows the water level in the tank at any point
