Calculating material balance and evaporating efficiency ofdouble decomposition reaction produce KNO_3;
生产硝酸钾的物料平衡及蒸发效率计算
The results showed that:1) the microwave drying process of wood was divided into three stages:accelerating,constant-speed and decelerating;2) during the microwave drying process,the average drying rate and specific moisture evaporation rate were higher when the wood moisture c.
结果表明:木材微波干燥过程可以分成加速段、恒速段和减速段3个阶段;在微波干燥过程中,木材含水率在纤维饱和点以上时,其平均干燥速率和水分蒸发效率比在纤维饱和点以下时的高;采用适当间歇辐射对木材输入微波能,微波能利用率较高。
Establishes an experimental system and studies the influence of recirculating air ratio on evaporative cooling efficiency in summer conditions.
搭建了相应的实验台,针对夏季实际工况条件,实验研究了再循环风量比例对蒸发冷却效率的影响,给出了合适的再循环风量范围。
