Water Cooled Waste heat flue gas Evaporator Economizer Integrated Optimal Performance

Water Cooled Wall Membrane Wall Boiler Evaporator Economizer Integrated Optimal Performance

Overview:
The membrane wall boiler adopts a vertical modular layout (water-cooled wall-evaporator-economizer integrated into one unit), and through compact structural design and matching with thermal shock-resistant materials, it ensures the stability of the system under extreme temperature fluctuations. Its gradient composite heat exchange technology is based on a graded heat recovery path (high-temperature flue gas radiation heat exchange → phase change heat absorption → countercurrent heat recovery), which realizes the step-by-step deep utilization of flue gas heat, significantly reduces the exhaust temperature and improves thermal efficiency. The surface of the water-cooled wall is integrated with high-temperature resistant and corrosion-resistant strengthening materials (such as silicon carbide ceramic coating), which can withstand ultra-high temperature flue gas erosion and high-dust, highly corrosive industrial environments, and is suitable for harsh waste heat recovery scenarios such as metallurgy and chemical industry.

Product Introduction:

The membrane wall boiler is based on a vertical integrated thermal shock resistant structure (water-cooled wall-evaporator-economizer integrated modular layout), adopts gradient composite heat exchange technology (1340℃ flue gas → water-cooled wall radiation heat exchange → evaporator phase change heat absorption → economizer countercurrent heat recovery), achieves 215℃ exhaust gas temperature control, and thermal efficiency exceeds 85.6% (8% higher than similar equipment). The water-cooled wall integrates silicon carbide ceramic coating, which can withstand direct scouring of 1340℃ high-temperature flue gas (instantaneous peak 1500℃), and is suitable for extreme industrial waste heat scenarios with dust content ≤50g/Nm³, such as metallurgical furnaces and glass kilns.

Advantages:

‌(1)Extreme high temperature resistance‌

Water-cooled wall ceramic coating + vertical package structure, the ability to resist thermal stress deformation is increased by 40%.

(‌2)High efficiency waste heat gradient recovery‌

The three-stage heat exchange unit operates in coordination, and the flue gas sensible heat recovery rate is increased by 12% year-on-year.

‌(3)Ultra-low maintenance cost‌

The packaged ash hopper design reduces the cleaning frequency by 60%, and the annual operation and maintenance cost is reduced by 35%.
