An Experimental Study on Latent Heat Recovery of Exhaust Wet Flue Gas

The experiment was conducted to investigate the heat transfer performance of wet flue gas in a vertical tube. The factors influencing the convective condensation of wet flue gas were experimentally investigated. The measured results indicate that the convective heat transfer of bulk flow and condensation heat transfer of vapor have significant contribution to the total heat transfer and the dominant transport mechanism is dependent upon the vapor fraction in mixture.

低阻力降为核心的低温吹风气潜热集中回收系统设计总结

固定层间歇式煤气发生炉排放的低温吹风气具有较高的潜热。通过采用非预混、蓄热型、不用合成弛放气、不用排烟引风机的微正压型低阻力降系统设计技术,并配套采用专用的微正压吹风气蒸汽锅炉机组,实现了吹风气潜热的高效集中回收及热力发电,取得了可观的经济效益。
