由于风冷对骨料兼有降温和保温的作用,风冷骨料现已成了混凝上预冷工程中的一项不可缺少的冷却措施。然而风冷的冷量利用率比较低,折合标准工况时的冷效一般只有30％左右。很重要的一个因素是我们对降低冷耗的措施研究还不够充分,设计中也未能对风冷的各项参数进行优选。 Due to the effect of air cooling on aggregate cooling and heat preservation, air-cooled aggregates have become an indispensable cooling measure in the pre-cooling process of coagulation. However, the utilization rate of air-cooled cold capacity is relatively low, and the cold efficiency equivalent to standard operating conditions is generally only about 30%. A very important factor is that our research on measures to reduce cold consumption is still not enough, and design has not been able to optimize the parameters of air-cooling.
