IGNITION ELECTRODE HT-EL-SF VOLCANO Marine Boiler Spark Assembly
The IGNITION ELECTRODE HT-EL-SF VOLCANO (Part / Model No: HT-EL-SF) is a heavy-duty, high-temperature ignition spark plug manufactured by Volcano Co., Ltd. for marine boilers and industrial burner systems. Designed to generate high-voltage electrical sparks for burner light-off, this component ensures fast, dependable ignition of light oil, heavy fuel oil (HFO), and gas burners under demanding operating conditions.
Constructed with high-grade alumina ceramic insulation and a heat-resistant stainless steel rod, the electrode withstands continuous exposure to severe furnace temperatures and thermal shock. Installed across Volcano marine auxiliary boilers, main steam plants, and shipboard incinerator units, the HT-EL-SF VOLCANO prevents delayed ignition hazards and guarantees clean, efficient combustion start-up.
Key Features of the Volcano HT-EL-SF Spark Plug
-
High-Dielectric Ceramic Insulator: Engineered from glazed high-purity ceramic to prevent electrical arc tracking and breakdown under high-voltage pulses.
-
Heat & Corrosion Resistant Alloy Rod: Features a high-temperature stainless steel core designed to withstand continuous burner flame exposure without bending or erosion.
-
Reliable High-Voltage Spark Generation: Delivers clean, consistent arc discharge when paired with standard 10kV / 12kV ignition transformers.
-
Secure Fastening Flange / Clamp Design: Designed for precise electrode tip alignment and gap maintenance inside burner blast tubes.
-
Vibration Resistant Assembly: Built to endure continuous engine room vibration and mechanical stress on marine vessels.
-
OEM Marine Boiler Compatibility: Direct-fit replacement for Volcano boiler assemblies, ensuring fast replacement during routine maintenance.
Primary Applications
