According to the application field, it can be divided into industrial burners, civil burners and special burners.

Oil burners are divided into light oil (such as diesel) and heavy oil burners (such as waste oil).

Gas burners are divided into natural gas burners, liquefied gas burners, city gas burners, biogas burners, etc.

And what we usually call the burner is the boiler burner.

How to choose a boiler burner?

The selection of a burner is a relatively complex technical issue. Generally, the following factors need to be considered:

7 Factors to Choosing Boiler Burner

Ⅰbrand

Users can choose the burner brand according to their own funds and equipment requirements.

Common boiler burner brands are divided into three series: German series (Weiser, Zach, Ouke, Riello, Paterson), Finland series (Olin, etc.), China (Opel, Baxter), etc.

Ⅱ Fuel

The user must first determine what kind of fuel to choose, and then choose the burner according to the type of fuel.

Common boiler fuels include: pulverized coal, oil (heavy oil, light oil) and gas (natural gas, liquefied gas, city gas, biogas), etc.

Ⅲ Technical parameters of equipment

1. Calorific value

2. Power

3. Furnace temperature and pressure

4. Gas heating value and pressure

Ⅳ Adjustment method

According to the requirements of the temperature accuracy of the equipment used, one-stage fire control, two-stage fire control, progressive and proportional adjustment burners can be selected.

Ⅴ Atomization Way

If you choose heavy oil as the fuel, you can choose mechanical atomizing burners and medium atomizing burners according to the viscosity of the fuel oil.

Ⅵ Region and environment

Different regions and different environments have different requirements for burners.

Ⅶ Special requirements for burner

Users can choose special burners according to equipment or application environment

When choosing a boiler burner, the most important point is that many variables need to be considered. You need to determine the required capacity, flame, temperature requirements, burner ratings, etc.

EPCB experts collected their five most valuable tips for selecting industrial burner.

5 Tips for Choosing a Burner

Burner selection tip 1: Know the burner rating

First, consider the burner rating. You need to look for a burner with a maximum input rating higher than the maximum burning rate of the equipment.

Burner selection tip 2: Determine the combustion load

The turn-down ratio, the ratio of the maximum capacity to the minimum capacity, shows the flexibility of the burner. If you are looking for a burner that can handle a variety of different load curves, look for a burner with a larger turndown ratio.

Burner selection tip 3: Consider installing

When choosing a burner, consider the ease of installation, access, and adjustment. The burner installation should allow the head to be removed and access to other important parts. This way you don't have to completely disassemble the burner, remove the wiring or move other equipment. Some burners require the installation of bulky refractory materials that are difficult to install and maintain.

Burner selection tip 4: Install a variable frequency drive

When installing a new burner, it is the ideal time to install a forced fan with a variable frequency drive (VFD). VFD is a good idea for any burner system, especially those that will not run at full capacity all the time.

Burner selection tip 5: Consult a burner expert

As the selection process becomes more difficult, talk to a boiler expert for advice.

Burner pit avoidance guide   

There are many imitations of well-known brand burners on the market, and it is difficult to distinguish the true from the false. Many unscrupulous merchants will use fakes to replace the real ones, thereby obtaining high profits. So how to distinguish these burners?

1. Riello burners, each burner has a QR code on the body, and there is only one, which is equivalent to everyone’s ID number, verify this anti-counterfeiting code to know the burner you bought Is it genuine?

2. Counterfeiters can only imitate some well-known brand old models of burners, and some of the latest models of burners cannot be imitated because they involve the latest technology. Therefore, buying the latest burners can avoid buying counterfeit and shoddy products.

Concluding

Purchasing a burner is a prudent choice. The quality of the burner is directly related to the thermal efficiency of the boiler. Sometimes, the price of a good burner is equivalent to the price of a boiler or even higher, so you must find a professional boiler system expert to buy a boiler supporting burner. If you encounter any problems when buying or using the boiler, please contact EPCB, and we will provide you with free consulting services.

What Are Industrial Burners?

If you’re not already familiar with industrial process equipment, industrial burners might seem otherworldly. You might picture a steam-filled boiler room from an old Hollywood film. Boilers and burners are often used interchangeably in conversation, but there are critical differences between the two pieces of industrial equipment. Let’s take a closer look at industrial burners’ functions and applications so you’re better prepared when you need to upgrade your burner system.

How Do Industrial Burners Work?

From the exterior, burners might just look like a hunk of metal to an untrained eye. However, inside the burner, there is an array of processes taking place. The device is used to mix oxygen with fuel to achieve controlled combustion. Fuel is injected into the system using a burner tip, which is essential to the heating process. The burner produces a specific flame and heat-release pattern that can be controlled within the combustion chamber, making it ideal for heating, melting, manufacturing, and steam production, among other things.

What Are the Industry Applications of Industrial Burners?

Industrial burners allow different types of facilities to control an open flame for a wide range of applications. Burners are most commonly used in industrial settings for heating purposes, as a means to generate steam or supply thermal energy, or applied in manufacturing processes. Additionally, they are used for other applications, such as:

What Are the Different Types of Industrial Burners?

Most people are familiar with typical cold air burners, which are found most often on residential properties. However, there is a multitude of burner types; the ones most commonly used in residential and commercial applications are:

• Cold air burners: Typically found on residential devices like gas ranges and furnaces.
• Hot air burners: These types of burners preheat incoming air using a central heat-exchanger device.
• Regenerative burners: Regenerative burners use a pair of burners to alternate between firing and exhausting, preheating a regenerative heat exchanger box to create hotter preheated air.
• Oxy-fuel burners: These burners use pure oxygen to burn with fuel instead of combustion air.

There are other factors of burners that vary from application to application. For example, varying velocity flames produce unique results. High-velocity burners have shorter, more intense flames, while lower velocity burners produce “lazy,” lame flames. For melting applications, medium velocity flames are preferred to drive heat to metal while still producing a uniform flame.
