Electric glow plug saves energy + CO2

A constant hot topic at our customers is the increase in energy efficiency at their heat treatment plants while maintaining a high level of productivity and production safety. AICHELIN has developed a solution that can be integrated easily and perfectly into existing heat treatment systems.


The challenge

  • For safe furnace operation, excess process gases must be flared in a controlled manner.

  • The energy consumption for this is high because the pilot burners required for safe operation are supplied with natural gas.

  • Each pilot burner produces about 6 – 8 tons of CO2/year, and often 2 of them are installed per system.

  • The infrastructure around the ignition source (valves, electric control) is also maintenance-intensive and thus cost-intensive.

The solution and its added value: Our new electric glow plug – an innovation ‘made by AICHELIN’.

This enables multiple savings:

  • Electrically ignited flaring saves energy and, especially when using green electricity, more than 75% CO2. 

  • The electric glow plug causes significantly less maintenance effort and costs. 

  • Plant safety and availability remain high.

  • The production interruption caused by the retrofit is low – the plants can be handed over warm for the retrofit.
