Abstract

The work is aimed at improving the energy efficiency of technologies for the production of precast concrete products through the rational organization of the heat and moisture treatment process in periodic installations. A study of the heat transfer mechanism based on criteria equations describing the heating patterns of the bases of molding tracks using registers on smooth pipes has been carried out. An analysis of the main patterns of the heat balance of the tracks made it possible to calculate the required amount of saturated steam to ensure the required performance of the heat treatment process of products with the given parameters of the heating registers and the use of a standard plate heat exchanger of the “steam-water” type for the preparation of the secondary coolant. The results of the work confirmed the high energy efficiency of the process of making reinforced concrete products on molding tracks with heating registers on smooth pipes.
