Learn the difference between lean phase and dense phase conveying for ash handling in your industry and how to choose the right system. Read
Ash handling is crucial in industries like power generation and cement production, requiring efficient systems to manage large volumes while minimizing wear and energy consumption. Two primary pneumatic conveying methods—dense phase and lean phase—offer distinct advantages. Dense phase systems operate at low velocity and high pressure, moving ash in compact slugs, reducing wear, and enhancing energy efficiency. In contrast, lean phase systems use high velocity and low pressure, keeping ash suspended in the air stream but causing more equipment wear. While dense phase is ideal for abrasive or fragile materials, lean phase suits lighter, non-abrasive ones. Selecting the right system depends on material properties, energy efficiency, and infrastructure constraints.
