HEGWEIN Gas Fired Igniters

Product catalog summary

Product Overview
The document provides a detailed overview of gas-fired igniters by DURAG GROUP, highlighting various models designed for industrial furnaces and boilers with heat release capacities from 2 kW to 1000 kW.

Specifications
Igniters are categorized by thermal performance, flame length, and outer tube diameter. They come with or without electrical components, integrated spark transformers, and ionization flame monitors, suitable for intermittent and continuous operations.

Common Features

Compact design with integrated components.
Built-in flame rod for efficient operation.
No high-voltage cabling required on-site.
Electromagnetic compatibility for most models.
Rugged, low-maintenance design, available in sizes from 2 kW to 10 MW.
Customizable outer tube lengths in 10-mm increments.
Compatible with various fuel types.
Available with flexible outer tubes for tilting burners.

Operational Details
Includes selection tables for heat release, flame length, outer tube diameter, and operation mode, tailored for EN or TRD standards. Provides data on gas and air port specifications, operating pressures, and ambient temperature ranges.

Models and Variants

Models without electrical components (e.g., ZGF, ZGU, ZGP).
Models with integrated spark transformers (e.g., ZTF, ZTU, ZTP).
Models with integrated spark transformers and ionization flame monitors (e.g., ZAF, ZDAF, ZAU, ZDAU).
Explosion-proof models for hazardous zones (e.g., ZAVEX, ZXAF).

Applications
Suitable for igniting gas burners up to 500 kW, medium-sized gas and oil burners, and large burners in boilers, designed for limited space and varying gas pressures.

Additional Information
A questionnaire/checklist is available for customization and inquiries. Further explosion-proof versions are available upon request.
