Indirect cooling drums for process heat recovery
When cooling hot solids from rotary kilns or calcining drums, efficient heat recovery and reduced process costs are critical. Ensuring effective cooling while minimizing primary energy expenditure is essential for improving operational efficiency and sustainability.
Enhance cooling efficiency with indirect heat recovery
The Indirect Cooling Drums from Allgaier Process Technology are designed for cooling hot and very hot solids, such as those from calcining drums and rotary kilns. These drums utilize indirect cooling to enable effective thermal energy recovery, moving the hot solid along one side of a separating apparatus wall while air cools from the other side. This separation ensures no direct contact between bulk material and cooling air, resulting in high thermal transfer efficiency. Particularly suited for materials like titanium dioxide and calcined gypsum, this method not only cools effectively but also reduces primary energy and fuel costs by using preheated, dust-free, and dry cooler exhaust air. The robust design ensures durability, complemented by environmental benefits from sustainable heat recovery.
