Industrial Burners for Energy Efficiency & Low NOx Emissions | Stiefel

Stiefel’s ignition transformers are designed for extreme burner environments. Their silicon carbide cores preserve insulation integrity at 800 °C while traditional ferrite cores fume at temperatures above 800 °C. In the reheating furnace of a steel mill, our transformers reduced ignition failures from weekly to annual occurrence and thermal cycling from daily 200 °C and 1200 °C prolonged set point variations. The compact size (<120 mm) allows installation in tight burner compartments and precision spark delivery by voltage regulated input of +/-15% ensures steady spark force while the range exceeding 15% input fluctuation preserves uninterrupted spark delivery. Each transformer undergoes durability tests exceeding 10,000 cycle load tests.
