Abstract

Background The efficiency of the air coolers largely determines the level of energy supply and production capacity. Heat exchangers in the refining industry mostly is the part air coolers. Great influence on the performance of air coolers have a compounds parameters of the tube bundle section, which is devoted to research this article. Aims and Objectives: - development of energy-efficient layout of the tube bundle in heat transfer section of air cooler; - quantitative estimation of efficiency of various configurations of pipe and heat transfer section of the air cooler beam; - building of the computational model of energy-efficient heat exchanger tube bundle sections. Methods The solution of these tasks could be performed using the methods of these full heat transfer with the boundary conditions of the second kind (T = const), using the similarity of processes of heat transfer and experiment. Results 1. Energy-efficient layout of the tube bundle heat exchanger-term section of the air coolers was developed. 2. Quantify energy efficiency of the tube bundles of different layouts and proven energy-efficiency heat transfer section of the proposed layout of the air cooler was estimated. 3. As a result, the experimental data were obtained by the model to calculate the air cooler with energy-efficient layout of pipe sections. Conclusion On the basis of experimental studies components substitution of the tube bundle in the heat transfer sections, which can increase energy efficiency of newly designed air cooler, was designed.
