Custom110 V 220V Silicon Nitride Ceramic Igniter 280W 600W Si3N4 Ceramic Heater

Brief

The silicon nitride ceramic igniter is a novel ignition component manufactured by embedding tungsten wire into silicon nitride powder, followed by hot pressing sintering and grinding processing.

Details

Silicon nitride igniter is an industrial ignition device made of high-performance ceramic materials, which has the characteristics of rapid heating in 8 seconds and high temperature resistance at 1450 ℃. It is widely used in industrial fields such as biomass boilers and gas equipment.

Characteristics of the Si3N4 ceramic igniter：

• Small size, light weight
• Excellent electrical insulation performance
• Ultra fast ignition: can reach 1000 ℃ within 8 seconds, with a maximum surface temperature of 1450 ℃. ‌‌
• Resistant to extreme environments: resistant to high temperature oxidation at 1400 ℃ and corrosion caused by combustion of particulate fuel. ‌‌
• Stable structure: Silicon nitride ceramic encapsulated resistor element, avoiding thermal expansion and contraction fracture

Key Application Areas

It is widely used in various high-temperature ignition devices, such as high-speed diesel engines, high-temperature ignition systems, petroleum media ignition, gas ignition, burner ignition, preheater ignition, mold heaters, packaging machinery, tobacco equipment, industrial equipment heating, combustion appliance ignition systems, mold heaters, and the petrochemical industry.

Usage tips:

• 1. Do not place any part of the ignition pad in the combustion chamber;
• 2. Keep a distance of 3-5cm from the particles, and use a fan to blow out hot air to ignite the particles;
• 3. During use, do not touch the ignition pad with metal or liquid;
• 4. When using the ignition pad, the temperature of the igniter should be monitored, and the surface temperature of the ignition pad should not exceed 1200 ℃ throughout the entire working process;
• 5. The packaging end of the ignition pad (i.e. the white ceramic part) should have good heat dissipation and the temperature should not exceed 400 ℃. After successful ignition, the ignition pad should be turned off in a timely manner;
• 6. Equipment with a larger hot zone area or the use of multiple ignition blades in combination can provide faster ignition speed.
