BTPC
The Burner Tilt Power Cylinder (BTPC) is a heavy-duty, trunnion-mounted pneumatic actuator designed for precise tilting of burner nozzle tips in corner-fired boilers. Built for continuous modulating duty, it ensures accurate positioning under harsh ambient conditions up to 120°C, with high humidity and dust/corrosion resistance.
FEATURES
- Rugged design for outdoor installation
- Field-adjustable speed and control characteristics
- Compatible with pneumatic or electro-pneumatic control
Application
- Boiler Flame Adjustment – Controls burner tilt angle for optimal combustion efficiency
- NOx Reduction – Helps lower emissions by adjusting flame position
- Load Balancing – Maintains uniform heat distribution across boiler sections
- Coal-Fired Power Plants – Essential for burner management in coal-based systems
Benefits
- Cylinder barrel from extruded profile aluminium with micro honed for extremely low friction.
- •Cushioning adjustable at both ends.
- Safe & easy maintenance
- Suitable for various services
- Rugged design
- •Wide thrust range.
- Permanent magnet is standard
