Cooler upgrade paves way for future production boost
Improvement in thermal efficiency and power consumption at Capitol
Case story: Capitol Aggregates
Capital Aggregates was looking to gain an extra 10% production from the existing calciner system. FLSmidth reviewed the plant layout from a mechanical, operational and construction standpoint - and it was decided to reuse the back portion of the old cooler casing for the new Cross-Bar cooler. In the FLSmidth Cross-Bar cooler, all bars are movable and reciprocate, so as to optimise transport effiency and enable horizontal installation. With the new FLSmidth Cross-Bar cooler in place, Capitol has experienced significant improvement in both thermal efficiency and power consumption: an increase in tertiary air temperature to over 900°C, and reduction in fan power by 20%.
