SPIRAL-TYPE TUBULAR HEAT EXCHANGER FOR HIGH-EFFICIENCY POWER GENERATION UNIT
Abstract
This paper examines the methodology for calculating a tubular heat exchanger designed to operate with energy carriers at high temperatures. Such heat exchangers are widely used in various industries, including energy, petrochemicals, metallurgy, and the food industry. Their efficiency directly impacts energy savings and the overall productivity of technological processes.
The study presents the main principles of thermal and hydraulic calculations of the heat exchanger, including the determination of heat flows, heat transfer coefficients, temperature gradients, and pressure losses in the system. Methods for optimizing the heat exchange process are considered, aimed at improving equipment efficiency by selecting appropriate materials, geometric parameters, and operating modes.
Special attention is given to the selection of structural parameters of the heat exchanger that ensure an optimal balance between heat transfer efficiency, energy consumption, and equipment durability. Factors affecting corrosion resistance and mechanical reliability of the structure are analyzed, along with methods to prevent contamination and fouling of the heat exchange surface.
The results obtained can be used for the development of new heat exchangers or the modernization of existing ones to enhance their performance and reduce energy costs.
