Diagram 1: Ceramic Igniter

Ceramic igniters continue to top the charts among other igniters in heating systems. Engineers call them the new game changers in the production of pellet boilers. The question is, what gave rise to this popularity? Today’s article will explain why and help you make more informed decisions if you’re looking to make a purchase. Let’s dive in!


What Are Ceramic Igniters?

Ceramic igniters are special heating devices designed to generate heat and start fires in equipment like pellet boilers, kilns, etc. Engineers create them from advanced ceramic materials with heat-resistant surfaces, such as silicon carbide and alumina, among others. They mainly use electricity to generate and spread heat automatically in heating systems.

Many modern industries use ceramic igniters to produce biomass pellet boilers, heaters, commercial kitchen equipment, and gas wall-mounted boilers. Today, they are already being utilized in many household applications. You’ll see them in water heaters, bathroom heaters, pressing irons, ring boilers, etc. In fact, they’re the driving force of most gas-powered equipment, industrial kilns, and barbecue grills.

They have become so popular globally, especially in the production of pellet boilers, and this is because:

  • They heat up very quickly.

  • They can handle very high temperatures.

  • They last longer and do not wear out or rust easily.

  • They’re excellent electrical insulators; hence a safer option compared to metal igniters.

So, if you’re considering heating up anything, these ceramic igniters for pellet stoves are there to make it easy for you. Interestingly, they’re not so complex. This could be another reason engineers prefer to use them in producing pellet boilers.

Now, let’s see some other amazing properties of ceramic igniters for pellet stoves:

  • High temperature resistance (operating temperatures) of up to 1,200°C.

  • The ceramic igniters heat up so fast when electricity passes through them (within 10 seconds).

  • They have an impressive ignition efficiency (over 90%)

  • They can withstand heat for long without decomposing or losing efficiency.

  • They consume 150 - 400 watts of power during the ignition phase.

  • They have an electrical voltage range of about 110 - 230 V AC.

  • They have a great lifespan (30,000 - 100,000 ignition cycles under normal use, which is about 3 - 10 years’ lifespan in pellet boilers.

  • The ignition pellet boilers have high thermal shock resistance.

  • They have a dielectric strength of about 10 - 15 kV/mm.

  • They’re excellent electrical insulators.

  • They have a high flexural strength ranging from 300 - 400 MPa

  • They possess a density of about 3.8 - 3.9 g/cm³

  • Their coefficient of thermal expansion is 7 - 8 × 10⁻⁶ /K.

  • They have excellent thermal conductivity of about 20 - 30 W/m·K at room temperature.


How Does a Ceramic Igniter Work?

Ceramic igniters heat up quickly when powered with electricity. Once electricity passes through them, their surface temperatures could get to 1,200°C within 10 - 15 seconds. This intense heat of the ceramic ignitors is what sparks up fires in the pellet boilers where they’re placed.

Simply put, they work by actively converting electrical energy into heat. Then use the produced heat to directly ignite pellets and start fires in the pellet boilers.

Ceramic igniters are simply the best and most efficient at igniting biomass burners, pellets, coal, wood chips, coke, etc. They have very high stability and are able to achieve ignition in a steady temperature of 60 - 90s at 1000°C.

Benefits of Alumina Ceramic Igniter

Alumina ceramic igniters are currently one of the best and most used ceramic igniters for pellet stoves globally. They have caused an increase in global sales and popularity of pellet boilers. This is due to the many interesting benefits they offer users. Some of them are:

  • Cost saving - They are highly economical and can save you a whole lot of money. How? They have higher temperature resistance and, as a result, can start ignition faster (60 seconds) compared to metal igniters. This will help you spend less on energy sources.

  • Impressive speed - They can help you ignite pellets in a matter of seconds (60-90 seconds).

  • Ceramic igniters have an excellent long lifespan compared to other types of igniters.

  • They’re the best at conserving energy. How? - They only use a small fraction of the energy consumption compared to an element heater or a traditional wire heater.

  • High temperature resistance of up to 1,200°C. at a steady pace.

  • Emission decrease in the ignition pellet boiler - Due to the shorter ignition phase of ceramic ignitors, your appliances will produce lesser particle emissions.

  • They’re easy to install and very compatible with virtually any heating system.

  • Better security - They’re excellent electrical insulators and do not overheat or rust easily.

Ceramic Igniters Vs Quartz Igniters

Ceramic igniters use ceramic as their main material, metal igniters are mostly made of metals while quartz igniters are mostly made of glass. However, while there are other types of igniters, the major ones that stand out are ceramic igniters, metal and quartz igniters, with ceramic igniters being the most used among them for the following reasons.

  • They have shorter ignition times compared to metal and quartz igniters.

  • They’re less likely to undergo oxidation compared to a metal or quartz igniter.

  • They have high strength and long lifespan compared to these other igniters.

  • Their ignition pellet boilers are more heat-resistant compared to quartz and metal igniters.

  • They’re more reliable, efficient, and energy-saving.

  • They’re safer to use because of the ceramic insulating property in them.
