Despite the harmfulness of absorbent fouling, its fundamental understanding is limited. The fouling behaviors in fluidized beds charged by CO₂ absorbent particles were therefore examined under various physical conditions to identify key parameters that can assist in the direct detection of absorbent fouling. The results demonstrate that the absorbent fouling conditions cooperatively rely on multiple parameters: the cooling water temperature, the riser temperature, and the air velocity, with a minimal impact of the particle type. The physical parameters were found to be vitally correlated with another crucial factor: the relative humidity, implying that modulation of the relative humidity would be essential to prevent absorbent fouling in fluidized beds.

基于温差的气固流化床换热器结垢检测

尽管吸收剂结垢是有害的，但对它的基本理解是有限的。_{因此，在各种物理条件下检查了由 CO 2}吸收剂颗粒充电的流化床中的结垢行为，以确定有助于直接检测吸收剂结垢的关键参数。结果表明，吸收剂结垢条件协同依赖多个参数：冷却水温度、提升管温度和空气速度，而颗粒类型的影响最小。发现物理参数与另一个关键因素密切相关：相对湿度，这意味着调节相对湿度对于防止流化床中的吸收剂结垢至关重要。
