Dual Recovery Water Tube Boiler Corner Tube Structure Compact Layout

Unlike traditional boilers, the corner tube boiler features a four-corner pressure-bearing circulation structure and achieves efficient energy conversion through an integrated membrane heat exchange interface. The system includes a built-in fuel compatibility platform for seamless switching between oil and gas fuel types, combined with intelligent temperature control strategies to precisely match wide adjustment requirements for steam/hot water production capacity. This design is particularly suitable for regional deployment with changing energy policies.

The corner tube boiler encloses the furnace and flue with a fully enclosed membrane water-cooled wall, combined with a flag-type heating surface structure, achieving thermal efficiency of ≥92% (exhaust temperature ≤120℃). The system can be equipped with optional spiral fin tube economizers or ORC waste heat power generation modules, increasing overall energy efficiency to 97%.

• Deep recovery of exhaust gas waste heat increases thermal efficiency by 3% or achieves comprehensive energy efficiency of 97% with waste heat power generation
• Nickel-based alloy coated water-cooled wall withstands high temperatures up to 1200℃, with sulfur corrosion resistance increased by 2 times and service life of ≥15 years
• Low exhaust temperature of 120℃ and below provides strong environmental compatibility
