Air Heaters
B&W can add, redesign or upgrade air heaters to solve boiler operating performance problems and improve unit efficiency. Solutions utilizing regenerative (rotary) or recuperative (tubular or plate) air heaters can be customized to address specific needs. We can also provide associated flue and duct, structural and controls modifications that accompany air heater upgrades.
For customers in the USA and Canada, B&W offers new air heater equipment, aftermarket replacement parts and upgrade services for most types of regenerative units, including Rothemühle designs and — through an agreement with GEECO Enercon Pvt. Limited, a recognized leader in air heater applications — Ljungström® and other OEMs’ designs.
Capabilities include:
- Field engineering support and comprehensive assessments to identify opportunities for optimizing performance,
- Integration of advanced heating elements (baskets) with a proprietary Leakage Reduction System (seals) to maximize thermal output, minimize leakage and reduce pressure drop,
- Validation of design and component upgrades with advanced simulation modeling analysis and performance testing,
- Replacement baskets and seals to maintain AH performance and improve boiler efficiency,
- Supply of spare parts, critical components and more to minimize downtime.
- Addition of air heater surface to improve unit performance
- Air heater surface cleaning equipment
- Complete computational modeling capabilities to solve air or flue gas plugging problems
- Fire suppression systems
