2005 Turk Solex AFA The BULKFLOW COOLER for Cooling Fertilizer Under Critical Ambient Conditions

About 15 years ago the Bulkflow Heat Exchanger was introduced into the fertilizer industry as an alternative method of cooling fertilizer granules and prills before storage. A heat exchanger for bulk solids was a new concept combining the engineering sciences of heat transfer and mass flow of bulk solids With approximately 70 fertilizer installations worldwide in phosphate, NPK and nitrogen fertilizer plants, this paper describes the Bulkflow Heat technology and the advantages it brings – very low energy consumption, low air emissions; compact design for plant retrofits and ease of maintenance.
Particular reference is made to the importance of lowering storage temperature to improve product quality; preventing condensation – an important topic in hot humid climates; and cost comparison with alternative technologies.
