【摘要】 实验证明,在低品位二次能源的利用中,利用过冷沸腾原理浓缩磷酸,可以使磷酸浓缩的蒸发负荷达到0.9kg/(m2·K·h),传热系数达引进专用浓缩装置的75%,而加热面的最高温度不超过70℃。这一现象将对湿法磷酸浓缩技术的工艺、设备、材质和操作运行管理产生重要影响。更多还原

【Abstract】 In the using of 2nd resources, the experiment of this paper proves that using the subcooled boiling theory in phosphoric condensation, it’s evaporate rate reaches 0.9kg/(m2·K·h), heat transfer coefficient occupies import special equipment’s 75%, and it’s heated wall temperature do not exceed 70℃.This technique will have a great influence on the humid-way phosphoric technology, equipment, material and the management of running.更多还原
