Boiler Classifications We Take into Consideration
Boilers are classified using a number of factors; therefore, our range of boiler design services will vary depending on the type of boiler you want for your project. They can be classified using the following:
- Number of Tubes
Depending on the total number of tubes, a boiler can be classified as either single tube or multitubular.
A single tube contains a single fire or water tube, thus the name. Boilers that fall under this classification include the Cornish boiler and the simple vertical boiler. On the other hand, a multitubular boiler has either two or more tubes. Such examples are the Locomotive, Lancashire, Cochran, Wilcox, and Babcock boilers.
- Axis of the Shell
Under this classification, a boiler can either be horizontal or vertical. A horizontal boiler is when the shell’s axis in the boiler is in a horizontal position. The same applies for a vertical boiler except that it’s in a vertical position.
Examples of horizontal boilers are Babcock and Lancashire while the Cochran boiler falls under the vertical boiler classification.
- Contents
A boiler can have either fire or water as its contents.
In a fire-tube boiler, hot gases pass through inside the tubes, with water surrounding the tubes outside. Compared to a water-tube boiler design, a fire-tube boiler has a simple construction and requires a less rigid water treatment. However, it requires a longer time to raise the steam pressure due to the large volume of water it needs. It also generates a lot of steam.
Some examples of fire-tube boilers include the Lancashire, Locomotive, Cochran, and Velcon boilers.
A water-tube design, on the other hand, has water flowing through the tubes with combustion gases passing outside. The main advantage of a water-tube boiler is that it requires less time to raise steam pressure. Basically, it’s the exact opposite of the fire-tube design.
A few examples are the Loeffler, Benson, Yarrow, La-Mont, and Wilcox boilers.
- The Furnace’s Position
Boilers can be classified as either externally fired or internally fired based on their furnace’s position. Externally fired boilers have the furnace outside of the boiler shell. Those that are classified as water-tube boilers will always have their furnace placed outside.
Meanwhile, internally fired boilers have the furnace inside the boiler shell. Most boilers with a fire-tube design are classified as internally fired, with a few exceptions.
- Usage
In terms of usage, a boiler can either be mobile or stationary. Stationary boilers are often used in power plants and industrial settings. Once installed, they can no longer be moved to another location. Meanwhile, mobile boilers can be easily transported due to their structure and design. Marine and locomotive boilers are just some examples.
- Steam and Water Circulation
Lastly, boilers can be classified based on how steam and water circulates. They’re classified into two: natural and forced circulation.
A natural circulation boiler relies on the convection currents which appear once water is heated. Some examples include Cochran and Lancashire boilers. On the other hand, a forced circulation boiler relies on a centrifugal pump which is driven using external power. Benson and La-Mont boilers fall under this classification.

Boilers are divided into three different types based on their application: commercial, condensing, and electric.
A commercial boiler includes a small water tube, fire tube, and electric resistance. It’s mostly used in various facilities such as schools, universities, office buildings, and hospitals. Of the various boiler types, commercial boilers can be considered the most diverse.
They can be fueled by either natural gas, propane, or even light oil. Depending on the quality of the boiler and its application, a commercial boiler can reach a thermal efficiency of up to 99%.
On the other hand, a condensing boiler uses either gas or oil and has the ability to reach up to 98% thermal efficiency which is possible by condensing water vapor in the exhaust gases. Due to its condensing design, it’s capable of recovering a portion of heat from the vapors which could otherwise get wasted.
Lastly, electric boilers produce the least amount of noise, not to mention they’re quite compact and easy to install. Moreover, they don’t have any extra combustion components which result in their overall minimal complexity. They’re the most preferred option for those in areas with affordable electricity costs such as Chicago and Oklahoma.
Our Boiler Designing Process
To make sure we can come up with a detailed and comprehensive design for your boiler installation project, we’ll have to work with you hand in hand so we can fully understand your specifications.
Ideally, your preliminary specifications should contain the following:
- Steam pressure
- Fuel
- Load range
- Steam temperature
- Steam penetration
A basic boiler design will often start using just these parameters. However, it will be subject to change as minor and major details regarding the operation and site-specific requirements are added along the way.
To further achieve an optimum design for your boiler, we recommend that you check the following steps in our boiler design process, so you can have an idea of how our design process goes.
- Next is to choose a steam drum. Its size can be determined through the following factors:
- Once we’re able to calculate the EPRS, we’ll then calculate the depth of the furnace and configure it using the dimensions of the front wall, EPRS value, and flame clearance requirement.
- After that, we’ll then calculate the required furnace volume using the guidelines for Volumetric Heat Release Rate. We also calculate the Furnace Exit Gas Temperature (FEGT) required and the Effective Projected Radiant Surface (EPRS) which can be calculated from the FEGT value. The EPRS refers to the surface of the tubes which are exposed to radiation. By calculating its value, we’ll be able to determine how many tubes are necessary for the furnace section.
- The next step is to fix the furnace geometry which is achieved by choosing the right burner based on the calculated fuel firing rate. This process also requires checking for both flame clearance requirement and burner size. From there, we proceed to configure the geometry of the front wall.
- After calculating the boiler’s heat duty, we’ll then proceed to calculate the burner’s heat duty as well as the fuel firing rate. The burner’s heat duty can actually be calculated using the rated steam enthalpy at the boiler’s Maximum Continuous Rating over the boiler’s efficiency.
- We start by calculating the heat duty of both the boiler and burner. Heat duty refers to how much heat is required to transfer from hot to cold over a unit of time. This is often done using a certain equation to compute the enthalpy of steam which is to be generated.
- Circulation ratio
- Boiler steaming capacity at MCR
- Expected load fluctuations
- Steam-water separation equipment
- Number of bank tubes that enter the steam drum
- Afterwards, we then calculate the surface for the economizer using the inlet flue gas temperature and your desired stack temperature. The point of computing the flue gas temperature is to make sure dew point corrosion is prevented. Basically, the higher the sulfur content is in the fuel, the higher the required flue gas temperature will be.
- The calculation of stack height comes next. This can be calculated using a number of factors including the natural draft and regulations which govern the disposal of pollutants. We’ll then decide on how many safety relief valves to include and where to place them.
- As soon as all the necessary mountings and fittings are determined, we’ll then proceed with the designing process. After the design is rendered, stress analysis calculations are then implemented. These calculations will help bring out the stress pattern for each part.This part is mandatory to be prepared underrated temperature and pressure. Additionally, it is mandatory to obtain approval from a regulating body before you even start the manufacturing or assembly of your boiler.
- Finally, we’ll then develop a control system and safety protection system for the boiler following NFPA-85 guidelines for burner management systems. After everything’s done, we’ll then hand you the completed design.
Since we will be working with you throughout the process, we’ll make sure to address any of your concerns and update the design based on any minor adjustments you had in mind. This way, we can assure that the final design we’ll be giving you is a complete work with all issues already solved in advance.
To put it simply, in order for us to create a detailed boiler design, we need to know the following:
- The economic feasibility of the boiler’s installation
- Ability to start quickly
- Conformity to safety standards and regulations
- Monetary cost
- Safety considerations
- Raw water quality (this is important to help determine the material for the boiler)
- Heat source
- The material’s tensile strength
- Required steam output (measured in tons per hour)
- Mechanical constraints
