What Are Immersion Tube Burners?

What Are Immersion Tube Burners?

Immersion tube burners are industrial burners that are used in process heating applications, such as boilers and heat exchangers. They are named "immersion" burners because the combustion chamber of the burner is located inside a metal tube, which is immersed into the fluid being heated.

In these burners, a fuel source, such as natural gas or propane, is mixed with air and ignited inside the tube. The heat from the combustion process transfers to the fluid, which is being heated, through the metal tube walls. The heat transfer rate can be controlled by adjusting the flow rate of the fuel and air mixture into the tube.

Immersion tube burners are used in a variety of industrial processes, such as heating water for steam generation, heating liquids for chemical processes, and heating gases for drying or other industrial processes. They are preferred in many applications because of their high thermal efficiency, ease of installation and maintenance, and precise temperature control.

Overall, immersion tube burners are a cost-effective and reliable solution for many industrial process heating applications, providing precise temperature control and efficient heat transfer.

Combustion Technology, LLC partners with Selas, the TFR Packaged Immersion Tube Burner manufacturer. The TFR is a pre-packaged burner system for liquid tanks with small bore (2.5" to 8" diameter) immersion tubes. TFR packages, when used with natural gas or propane, are intended to create high-fire thermal inputs up to 3.5 MM Btu/hr. A powerful, high-velocity flame wipes the tube's surface, encouraging up to 80% system efficiency. Firing rates can be increased with bigger capacity, external combustion air blowers, and induced draft exhaust fans.

Combustion Efficiency in Large Scale Hemp Drying Applications

Combustion Efficiency in Large Scale Hemp Drying Applications

Efficient fuel combustion plays a critical role in large-scale hemp drying applications as it allows for the safe and efficient drying of the hemp plant material. The hemp material is often quite moist after it has been harvested, and it must be dried before it can be processed for various industrial and consumer applications.

One way to dry the hemp material is by using a large-scale dryer, which typically burns a fuel, such as natural gas, propane, or oil, to generate heat. The heat is then used to dry the hemp material. In order for the drying process to be efficient, the fuel must be burned in a controlled and consistent manner. This is where efficient fuel combustion comes into play.

Efficient fuel combustion ensures that the fuel is being burned in the most optimal way possible. This means that the fuel is being burned at the correct temperature, with the correct amount of oxygen, and in the correct mixture with other fuels (if applicable). This allows for the maximum amount of heat to be generated from a given amount of fuel, and thus allows for the hemp to be dried in the most efficient manner possible.

To achieve efficient fuel combustion in large scale hemp drying applications, several factors must be considered and controlled. These include:
  • Fuel type and quality: The type and quality of fuel used can have a significant impact on the efficiency of combustion. Using a higher quality fuel can lead to better combustion efficiency, and thus, less fuel consumption.
  • Air/Oxygen supply: Adequate air supply is essential for efficient fuel combustion. Insufficient air supply can lead to incomplete combustion, which can lead to decreased efficiency, increased emissions, and even fire hazards.
  • Combustion chamber design: The design of the combustion chamber can also play a role in combustion efficiency. A well-designed chamber can help to ensure that the fuel is being burned in the most optimal way possible.
  • Temperature control: Proper temperature control can also help to ensure efficient fuel combustion. Burning the fuel at too low a temperature can lead to incomplete combustion, while burning it at too high a temperature can lead to increased emissions.
Overall, efficient fuel combustion is critical in large-scale hemp drying applications as it allows for the safe, efficient, and cost-effective drying of the hemp plant material. Ensuring that all the factors involved in combustion are optimized and well-controlled is key to the efficient combustion process.
