Reformed gas waste heat boiler with variable tube sheet
In industrial processes where high thermal efficiency and effective waste heat recovery are paramount, managing gas inlet temperatures and steam pressures is crucial. Challenges often include tube sheet deformation and maintenance complications due to high-pressure loads and temperature variations.
Enhance thermal efficiency and reliability
The reformed gas waste heat boiler by BORSIG, featuring a thin stiffened tube sheet design, is engineered for optimizing waste heat recovery in demanding applications. Designed for gas inlet temperatures up to 1,200°C and steam pressures up to 160 bar, this system’s unique stiffened tube sheet effectively transfers pressure loads into the shell, maintaining flatness and minimizing deformation. This optimized engineering results in efficient cooling and low metal temperatures, extending the boiler’s lifespan and reliability. The full penetration welds on the water side of the tube sheets prevent crevice corrosion. Additionally, an internal gas-side bypass allows precise control of gas outlet temperature through a single valve, effectively managing mass flow through both the bundle and bypass tubes. Available for both horizontal and vertical installations, this system boasts no lifetime limitations due to fatigue cycles.
Benefits
- High thermal efficiency with low metal temperature
