1. First-class brand
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, Oker, Riello, Paterson), Finnish series (Olin, etc.), domestic (Opel, Baxter), etc.
2. Fuel
Users must first determine what fuel to choose, and then choose the burner according to the type of fuel.
Common boiler fuels include: pulverized coal, oil products (heavy oil, light oil) and gas products (natural gas, liquefied gas, city gas, biogas),etc.
3. Equipment technical parameters
Calorific value
Power
Furnace temperature, pressure
Gas calorific value and pressure
4. 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.
5. Atomization method
If heavy oil is selected as the fuel, mechanical atomization burner and medium atomization burner can be selected according to the viscosity of the fuel oil.
6. Region and Environment
Different regions and environments have different requirements for burners.
7. Special requirements for burners
Users can choose special burners based on the equipment or application environment
When choosing a boiler burner, the most important thing is that there are many variables to consider. You need to determine the required capacity, flame, temperature requirements, burner rating, etc.
EPCB experts have collected five of the most valuable suggestions for choosing industrial burners.
Burner selection tip 1: Understand the burner rating
First, consider the burner rating. You need to look for a burner with a maximum input rating that is higher than the maximum firing rate of the equipment.
Burner selection tip 2: Determine the combustion load
The turndown ratio, which is the ratio of maximum capacity to minimum capacity, indicates 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 large turndown ratio.
Burner selection tip 3: Consider installation
When choosing a burner, consider its ease of installation, maintenance, and adjustment. The burner should be installed to allow the head to be removed and other important parts to be inspected. This way, you don’t have to completely disassemble the burner, remove 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 best to install a forced fan with a variable frequency drive (VFD). A VFD is a good idea for any burner system, especially one that will not be running at full capacity all the time.
Burner Selection Tip 5: Consult a Burner Expert
As the selection process becomes increasingly difficult, ask a boiler expert for advice.
