D-VE 500
Retraction unit
Pneumatic retraction unit for safe retraction and extension of the ignition lance before and after successful ignition. Used to prevent excessive temperatures and wear at the ignition tip, helping to reduce costs for spare parts.
Functionality: Pneumatic retraction unit with piston rod cylinder
Features
- Automatic retraction and extension of ignition lances
- Hollow piston rod cylinder to hold the ignition lance
- Flexible traverse length to adapt to the application
- Also available in explosion proof version
Benefits
- Reduced wear of the ignition tip through retraction from the hot area after ignition
- Safe and reliable ignition due to optimum positioning of the ignition tip
Applications
- Coal-fired power plants with oil pilot burners
- Marine: Ignition of auxiliary and special boilers on ships using gas and/or oil as fuel
- Refineries: Use in potentially explosive atmospheres for ignition of gas, oil or other liquid fuels
