The flue pulse igniter is a type of gas burner igniter that is used to ignite gas burners quickly and safely. It also known as a gas burner lighter, is commonly used in applications such as kitchen hobs, ovens, and grills. Flue pulse igniters work by creating a spark that ignites the gas when it is released from the burner. This happens through a pulse system that sends a spark to ignite the gas. Flue pulse igniters are preferred over manual ignition methods, such as matches or lighters, because they are safer and easier to use.Flue pulse igniters come in different types, which include;
Piezzo Flue Pulse Igniter
Piezo flue pulse igniters usually produce an electric spark by pressing a button or turning a knob. The spark then ignites the gas. This type of flue pulse is generally known for its reliability and safety. It does not depend on the draws of airflow through the flue to work. Additionally, piezo electric pulse igniters are commonly used in outdoor grills and camping stoves. This is because they can be used in wet conditions and are not affected by moisture.
Electronic Flue Pulse Igniter
The electronic flue pulse igniter is powered by a battery or a mains power supply. It usually creates a series of sparks or a continuous spark that ignites the gas. Electronic flue pulse igniters are more consistent and easier to operate compared to piezo flue pulse igniters. This is because they do not depend on manual operation to create a spark. However, electronic flue pulse igniters are more complex and have higher maintenance costs.
Hot Surface Flue Pulse Igniter
The hot surface flue pulse igniter uses a glowing element that ignites the gas once it reaches a high temperature. Commonly found in gas furnaces and boilers, this kind of flue pulse igniter is simple and reliable. Hot surface flue pulse igniters, however, require a high power supply and take longer to ignite the gas.
A flue pulse igniter is carefully designed to fulfill consistent ignition needs in flue gas applications. This specialized equipment boasts a range of features that ensure high reliability, safety, and effective performance.
Stainless Steel Construction
With careful attention to the construction materials, the igniter features a robust stainless steel construction. This allows it to withstand harsh environmental conditions. It is durable and resistant to corrosion, which ensures long-term service and reliability, even in extremely high temperatures.
IP55/66 Protection Level
Flue pulse igniters are critical components in ignition systems. They are usually installed in locations that need absolute safety against potential hazards. With an IP55/66 protection level, the devices are dust-tight and water-resistant to ensure safe and reliable operation with minimal risk of failure. This protection ensures stable operation by shielding the delicate internal components from damage due to water ingress or dust contamination.
High-Temperature Resistance
To perform well in flue gas ignition applications safely, the pulse igniter should have good temperature resistance. Igniters with silicon nitride and stainless steel igniter heads resist up to 1300 °C, while igniter heads made from chrome-alumina can resist up to 1800 °C. This provides fast, reliable, and safe ignition of flue gases.
Explosion-Proof Design
In explosive applications environments, ensuring safety is critical. Flue pulse igniters come with an explosion-proof design that guarantees safe and reliable operation. They comply with regulatory standards for hazardous locations and have an explosion-proof housing. This housing encloses all the components and withstands explosions without causing harm to people or property.
UV and Flame Detection
For applications where flame presence is critical for safe operation, the igniter incorporates UV detection to improve safety and reliability. This allows the detection of flame via the ultraviolet radiation emitted by the flame. If there is a flame failure, the ignitor triggers an alarm or shuts down the system to prevent accidents.
Boosted Ignition Energy
In ignition applications with high ignition energy required or difficult to ignite fuels, the pulse igniter provides boosted ignition energy for fast and reliable ignition. This is achieved via an electric spark or high-energy pulse to ignite the fuel, ensuring successful ignition under challenging conditions.
Flue pulse igniters are versatile ignition systems applicable in several industries, including petroleum, metalworking, and power generation.
Brass and copper manufacturing:
Flue pulse igniters are useful in igniting burners in brass and copper manufacturing. The burners are in furnaces that smelt metal. The igniters safely ignite burners, leading to furnace temperature stability, which is important in metal heating and pouring operations.
Pulp and paper production:
In the pulp and paper production industry, flue pulse igniters are responsible for burner ignition in recovery boilers. Recovery boilers are important in the chemical recovery processes and energy generation. The flue pulse igniter ensures efficient combustion in the recovery boilers. This is important for safety and reliability in the pulp and paper production processes.

Before buying flame igniters for sale, buyers should know that not all flame igniters are the same. They come with unique specifications for various uses. For instance, some flue igniters may have longer probes to reach deeper into the fuel bed. On the other hand, some might be shorter for shallower applications. Regardless, here are some key specifications to consider when buying.
Length
The lengths of flue pulse igniters can vary. However, most flue igniters are approximately 700mm long but can be customized to suit specific requirements. Buyers are advised to take accurate measurements of the areas that need ignition before placing an order. This will ensure they choose an ideal size that will fit perfectly in the designated space.
Power Supply Voltage
Flue pulse igniters are designed to operate using different power supply voltages. These can range between 12V and 60V. Ideally, the voltage capacity to choose will depend on the specific application requirements. Buyers should consult an expert to help them understand more about power supply voltages for igniters before placing any orders.
