- **Caution**: 

### Q: What materials are best for high-temperature swirl vane assemblies?
**A**: For extreme heat applications, we recommend heat-resistant stainless steels like 310S or 253MA, or high-temperature nickel alloys such as Inconel for superior durability and corrosion resistance.

### Q: How does a swirl vane assembly improve combustion efficiency?
**A**: The angled vanes create rotational motion in fluid flow, which stabilizes flame patterns, promotes better fuel-air mixing, reduces emissions, and enhances overall combustion system performance.

### Q: What maintenance is required for swirl vane assemblies?
**A**: Regular inspection for thermal fatigue, corrosion, and buildup is recommended. Components like retaining rings and shrouds should be checked for secure fit, with replacement needed if deformation or excessive wear occurs.
