Abstract A new system developed here conducts the thermal management of the flue gas from the cement industry and employs this heat for the drying of raw materials before reaching to the preheating section. As of now, an additional amount of heat is used to provide the drying section with hot air while this proposed configuration recovers the heat from the same plant and employs it for drying purpose. This approach also results in cost saving as this configuration decreases the cost of heating the ambient air to provide the drying section with hot air. The entire system is simulated using the Aspen Plus industrial software. A comprehensive thermodynamic analysis is conducted for each component of the proposed system keeping more focus on the drying section. Numerous parametric and sensitivity studies are conducted to investigate the system performance, pressure drop and raw materials drying. The energy and exergy efficiencies of the drying process are found to be 55.6% and 24.17%. On the basis of the present results achieved, one can say that this novel configuration can be proved as a benchmark for the cement industry and has the capability to reduce the cost as well.

一种新型节能单级闪蒸干燥系统，集成了工业热回收应用

摘要 这里开发的一种新系统对来自水泥工业的烟气进行热管理，并在到达预热段之前利用这种热量对原材料进行干燥。到目前为止，额外的热量用于为干燥部分提供热空气，而这种建议的配置从同一设备中回收热量并将其用于干燥目的。这种方法还节省了成本，因为这种配置降低了加热环境空气以向干燥部分提供热空气的成本。整个系统使用 Aspen Plus 工业软件进行仿真。对拟议系统的每个组件进行了全面的热力学分析，重点放在干燥部分。进行了大量参数和灵敏度研究以研究系统性能、压降和原材料干燥。发现干燥过程的能量和火用效率分别为 55.6% 和 24.17%。根据目前取得的成果，可以说这种新颖的配置可以证明是水泥行业的标杆，并且具有降低成本的能力。
