ESP discharge electrodes

Pipe & Spike Type Discharge Electrodes are high-efficiency corona-generating components used in Electrostatic Precipitators (ESPs) for industrial air pollution control. These electrodes are specifically designed to deliver consistent and uniform corona discharge across the gas stream, ensuring effective ionization of particulate matter.

Key Features:

• Design: Consists of a central rigid pipe with multiple strategically welded sharp spikes (or barbs) along its length to ensure a strong and stable corona field.

• Material: Typically manufactured from high-tensile galvanized steel, stainless steel, or corrosion-resistant alloys to withstand high-voltage environments and chemical exposure.

• Corrosion Resistance: Surface treatment or coating options available for extended service life, especially in chemically aggressive or high-temperature flue gas conditions.

• Mechanical Strength: Engineered for excellent structural rigidity to prevent bending, sagging, or vibration under operating stresses.

• Corona Stability: Spike arrangement ensures low corona onset voltage and stable corona current for maximum ionization efficiency.

Applications:

• Used in Dry ESPs and Wet ESPs across a wide range of industries including:

  • Thermal Power Plants

  • Cement Plants

  • Steel Plants

  • Chemical & Fertilizer Units

  • Pulp & Paper Industries

Advantages:

• Easy installation and compatibility with various ESP frame structures.

• Minimal maintenance due to rugged and self-cleaning design.

• Enhanced dust charging efficiency even in high-resistivity or sticky dust environments.
