Abstract
Modeling of heat exchanger with pseudo origemail attachment systems for the construction industry
Incoming article date: 20.03.2017The article is devoted to the problem of modeling heat exchangers with fluidized packing of disperse material whenшы used in aspiration schemes at construction industry enterprises. Innovative transformation of industry and construction industry is associated with the most complete and effective use of thermal, energy potentials including low-potential secondary resources. The use of waste gas heat from equipment during thermal processing of raw materials and products, and ejecting in aspiration schemes, allows to reduce the specific consumption of fuel burned per unit of output production by the construction industry enterprises. There is presented an approach to modeling and calculation of heat transfer in the apparatus of the proposed design with a nozzle in the form of a fluidized bed of granules of a dispersed material in this article. There is presented the result of the executed experimental research and modeling in the form of generalized regression dependence for the the Nusselt criteria relations to determine the heat transfer coefficient from the particles to the solid tube’ wall where water is circulated inside within the fluidized bed granules in this article. It was described generalized form of the regression relation for the calculation of heat transfer in a heat exchanger with a fluidized bed of packing dispersed materials in the form of granules in this article.
