Ceramic Ignition Needle, High Temperature Resistance ≥ 800º C, Fast Ignition

Product Description

Scope of application

• • Civil field: Domestic gas stoves, gas water heaters, wall-hung boilers, etc., provide stable ignition and flameout protection for daily cooking or heating equipment.
  • Industrial field: Large-scale equipment such as industrial kilns, gas-fired boilers, and burners, which are suitable for high-load combustion scenarios, ensuring ignition efficiency and operational safety.

 

 

How it works

 

The Ion rod ignition needle is a precision component integrating ion sensing and ignition functions. It is widely used in gas stoves, water heaters, industrial burners and other equipment. It ignites gas through high-voltage discharge, synchronously monitors the flame status, and realizes the dual functions of "ignition + flame detection".

 

Ignition function:

The metal needle body of the ion rod ignition needle can release high-voltage electric sparks (usually with a voltage of 5,000-10,000V) by connecting to a high-voltage generator, instantly breaking down the gas-air mixture to complete the ignition action and ensure stable ignition of the gas.

 

 

 

Flame detection function:

It utilizes the "flame ionization" principle - there are a large number of ions in the flame, and when the flame comes into contact with the ion rod, a weak current will be formed. By detecting this current signal, the equipment can determine whether the flame is burning normally. If an accidental flameout occurs, it can quickly trigger protection mechanisms such as gas cutoff, thereby improving safety in use.

 

Technical features

 

• Core components: Composed of an ion sensing rod (responsible for flame detection), an ignition needle (responsible for discharge ignition), and an insulating shell (usually made of high-temperature resistant ceramic material). Some models integrate the two into the same rod body, featuring a compact structure.

• Material advantages:

• The ignition needle and ion sensing rod are mostly made of high-temperature resistant alloys (such as stainless steel), which can withstand long-term baking by high-temperature flames, and have anti-oxidation and corrosion resistance properties.

 

 

 

 

• Installation: The position must be fixed in accordance with the equipment manual to ensure that the contact point between the ignition needle and the flame is accurate (usually 3-5mm away from the burner fire hole). The ion sensing rod should be directly opposite the core area of the flame to ensure sensitive signal detection.

• Maintenance: Regularly clean the surface oil stains and carbon deposits (can be gently wiped with fine sandpaper) to prevent impurities from affecting ignition efficiency or signal detection; check whether the insulating shell is damaged, and if there are cracks, it must be replaced in time to prevent the risk of electric leakage.

 

 

• Integration of dual functions: It realizes both ignition and flame detection, simplifies the equipment structure, and reduces the probability of failure.

• Rapid response: The ignition spark is strong, and the ignition speed is fast; after the flame is extinguished, the ion sensing signal can trigger protection within 0.1-0.3 seconds, ensuring high safety.

• Strong durability: The combination of high-temperature resistant materials and precision craftsmanship results in a long service life, and it is compatible with various gas types (natural gas, liquefied gas, artificial gas, etc.).
