Heat exchangers.The Bulkflow heat exchanger heat exchanger Any of several devices that transfer heat from a hot to a cold fluid. In many engineering applications, one fluid needs to be heated and another cooled, a requirement economically accomplished by a heat exchanger. uses mass flow and a bank of evenly spaced vertical hollow plates connected to a cooling water system to effectively cool bulk powder. Besides a wide variety of powder, other materials that can be heated or cooled include pellets, granules Granules Small packets of reactive chemicals stored within cells. Mentioned in: Allergic Rhinitis, Allergies and other bulk solids. The Bulkflow heat exchanger combines two technologies, including heat transfer through moving beds of solids and the mass flow of bulk solids. The equipment consists of a number of vertical, closely spaced, hollow stainless steel stainless steel: see steel. stainless steel Any of a family of alloy steels usually containing 10–30% chromium. The presence of chromium, together with low carbon content, gives remarkable resistance to corrosion and heat. plates. Bulk solids or powders pass slowly downward between the plates as heat transfer fluid flows through the interior of the plates to heat or cool the material by conduction. For cooling, water or glycol glycol (glī`kōl), dihydric alcohol in which the two hydroxyl groups are bonded to different carbon atoms; the general formula for a glycol is (CH2)n(OH)2. is circulated through the plates, and for heating, steam is most commonly used, but hot water or thermal oil can also be used effectively.
