A well-proven design for heavy industrial use and easy maintenance

John Cockerill’s Denarad Boiler is a single-drum boiler with natural circulation and a vertical flue gas flow. This well-proven design was developed for heavy industrial use and easy maintenance.

• Self-supporting boiler with water cooled furnace walls
• Meets steam equipment design, fabrication and safety regulations for international codes and standards
• All tubes connected to the steam drum and to the headers are welded
• Convection parts (super-heaters, evaporators and economizers) are pre-assembled in the workshop
• Hydro-testing of convection parts performed prior to assembly on-site
• Outer drum designed to enable fast start-up & load changes
• Available cleaning systems – soot blowers, water guns, wall blowers and/ or gravitational bullet cleaning systems
• Capable of meeting stringent low NOx emission requirements, (low NOx burners, flue gas recirculation, SNCR or SCR systems)

Main Strengths

• Operational flexibility from 10 to 100% MCR (Maximum Continuous Rate)
• High thermal efficiency up to 97.5% (LHV)
• High availability up to 99.5%
• Low-corrosion design features
• Guaranteed low NOx
• Optional Bundle cleaning systems
• Designed for easy maintenance
