Introduction
Waste incineration plants have evolved to minimize environmental impact while recovering energy from waste. The Keppel Seghers Boiler Prism is a key component in this process, enhancing energy recovery and reducing corrosion risks.

Principle
The Boiler Prism addresses high-temperature corrosion, a major issue in waste-to-energy plants, by acting as a dynamic mixer with secondary air injection. It is water-cooled, refractory-lined, and integrated with the boiler's natural circulation system.

Application
The Boiler Prism is suitable for medium to large waste-to-energy plants and can be installed in new or existing facilities. It divides flue gas flow for optimal secondary air injection, improving turbulence and process control.

Process Description
Positioned at the combustion chamber exit, the prism-shaped component ensures efficient post-combustion of flue gas. It features internal collectors with nozzles for secondary air, enhancing flue gas mixing and reducing penetration depth. This design allows for quicker heating and optimal oxygen distribution, resulting in efficient combustion.

Features
- Optimized secondary air injection for uniform flue gas distribution
- Customizable design using computational fluid dynamics
- Proven technology against high-temperature corrosion
- Increases plant throughput and availability
- Reduces manual cleaning frequency and reagent consumption
- Available for retrofit installations

Conclusion
The Keppel Seghers Boiler Prism enhances waste-to-energy plant efficiency by improving combustion processes and reducing corrosion, leading to longer operation times and lower maintenance requirements.
