Usage & Maintenance Guidelines of Quartz Glass Burner
Proper handling, installation, and maintenance of quartz glass burners ensures optimal performance and maximum service life. Follow these guidelines to maintain your quartz burner components.
Installation Guidelines
- Ensure all connections are gas-tight using appropriate fittings. Avoid overtightening which can damage the quartz material.
- Use the recommended gas pressures and flow rates specified for your particular burner model to maintain optimal flame characteristics.
- Allow gradual warm-up and cool-down periods of at least 5-10 minutes to minimize thermal shock and extend component life.
Cleaning and Maintenance
- Clean quartz burner nozzles using ultrapure deionized water or laboratory-grade solvents. For stubborn deposits, use dilute (5%) hydrofluoric acid solution with proper safety protocols.
- Inspect regularly for devitrification (whitening of the quartz), which indicates the need for replacement. Typical operating lifespan ranges from 300-500 hours depending on application.
- Store in clean, dry conditions in protective packaging to prevent dust accumulation or physical damage when not in use.
2. Use gas filters upstream of the burner to prevent particulate contamination that can block the fine core channels.
3. For applications requiring precise flame characteristics, consider using digital flow controllers to maintain consistent gas delivery parameters.

FAQ
Q: What is a quartz torch used for?
A: Quartz torches are used in laboratory equipment, glass processing, material analysis, and industrial heating applications where a clean, high-temperature flame is required. They provide precise flame control, chemical resistance, and contamination-free operation for applications including spectroscopy, glass joining, and specialized material processing.
Q: Can quartz torches withstand high temperatures?
A: Yes, quartz torches are specifically engineered for high-temperature applications. Our quartz glass burners maintain structural integrity and performance at continuous operating temperatures up to 1200°C. The material’s low coefficient of thermal expansion (5.5 × 10⁻⁷/°C) provides excellent thermal shock resistance, allowing for rapid temperature changes without cracking or deformation.
Q: What core configuration is best for glass processing?
A: For glass processing applications, 7-15 core configurations typically provide the optimal balance of heat distribution and precision. Smaller work (e.g., laboratory glassware) generally benefits from 7-9 cores, while larger industrial glass processing may require 15-21 cores for sufficient heat output. The specific arrangement of cores also affects flame characteristics—concentric patterns provide even heating while asymmetric designs can create directional heating profiles.
Q: How do you clean a quartz torch nozzle?
A: For routine cleaning, rinse quartz torch nozzles with ultrapure deionized water followed by a laboratory-grade solvent like acetone or methanol. For stubborn deposits, a dilute (5%) hydrofluoric acid solution can be used with proper safety protocols. Alternatively, a hydrogen peroxide/ammonia solution (1:1:5 ratio of 30% H₂O₂, NH₄OH, H₂O) effectively removes organic contaminants. Always rinse thoroughly with deionized water and dry with filtered compressed air or nitrogen.
Q: Can quartz glass burners be customized?
A: Yes, TOQUARTZ specializes in custom quartz glass burner solutions. We can customize core configurations (3-36+ cores), dimensions, interface connections, and special geometries according to your technical drawings or requirements. Our engineering team provides design support to optimize performance for specific applications, with prototype development typically completed within 2-3 weeks.
