Abstract: The article presents the results of research on organizational and technological methods for insulating the walls of cylindrical water storage tanks. Based on the analysis of regulatory requirements for the calculation and design of thermal insulation of tanks, existing engineering methods, the main factors influencing the choice of thermal insulation structure were determined. A classification of factors influencing the choice of heat-insulating material has been developed. Based on the studies of the characteristics and range of modern heat-insulating materials for tank insulation, a comparative analysis of the cost of materials per 1 m2 was made with the same heat saving indicators. The calculation of labor costs for the process of thermal insulation using technologies that have become most widespread in the practice of thermal insulation of tanks has been carried out, which made it possible to quantify the labor intensity per 100 m2 of insulated area. Characteristic differences in the structure of processes are revealed, which are largely determined by the requirements for the insulated surface, the temperature of the work, and the arrangement of the cover layer for thermal insulation. A comparative analysis of the labor intensity of the complex process of tank insulation, carried out for the most common technologies, helped to identify the most effective methods. The technical and economic indicators of the adopted organizational and technological solutions were obtained when insulating a cylindrical tank D = 24 m, H = 4.8 m by spraying with polyurethane foam, with a total thickness of the heat-insulating layer of 50 mm.
Keywords: thermal insulation structure, cover layer, cylindrical tank, energy consumption, labor intensity, cost, technical and economic indicators.
