Powder Cooling.For industries processing very high temperature bulk solids, the company offers a high temperature bulk powder cooling system cooling system: see air conditioning; internal-combustion engine; refrigeration. cooling system Apparatus used to keep the temperature of a structure or device from exceeding limits imposed by needs of safety and efficiency. with an innovative tube exchanger that minimizes thermal stresses and accommodates thermal expansion thermal expansion Increase in volume of a material as its temperature is increased, usually expressed as a fractional change in dimensions per unit temperature change. . The high temperature model cools bulk solids with temperatures up to 1,832[degrees]F (1,000[degrees]C). For these very high temperatures, the company developed a system using horizontal water-cooled tubes as the heat exchange surface. Bulk powder flows via gravity over the cooling tubes while indirectly cooled. The geometry of the tube is perfectly uniform with even temperatures throughout the tube wall to avoid hot spots hot spots acute moist dermatitis. and high local stresses. Several industries process very high temperature bulk solids. This equipment features tubes that are arranged in a serpentine serpentine (sûr`pəntēn, –tīn), hydrous silicate of magnesium. It occurs in crystalline form only as a pseudomorph having the form of some other mineral and is generally found in the form of chrysotile (silky fibers) and design connected to manifolds at the top and bottom of each section. The tubes penetrate the front and back wall of the exchanger, with all welded connections outside of the product flow. The tubes are not welded to the front and back wall to allow full movement. A product seal where the tube penetrates the front and back wall prevents product leakage. The front and back walls are typically refractory refractory Material that is not deformed or damaged by high temperatures, used to make crucibles, incinerators, insulation, and furnaces, particularly metallurgical furnaces. lines on the inside (product side) to keep the temperature of the walls low, minimizing thermal expansion. The technology combines zero emissions, lower energy consumption and lower capital costs with exceptional results, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company. Benefits are said to include a gentle, improved product flow to prevent product attrition, prevention of potential caking in storage and slower degradation and speed time to packaging. Safe and compact, the system easily integrates on line to existing equipment, according to the manufacturer. For large capacities, the 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. can be of modular construction with multiple banks mounted directly in series to achieve the full thermal duty. A combination unit with plate design is also optional. Bulkflow Technologies www.bulkflow.com [ILLUSTRATION OMITTED] |
