Inspection of the Thermal State of the Insulating Material on the Surface of a Steam-Water Heat Exchanger under Operating Conditions

Abstract:

The study assesses the efficiency of the heat-insulating coating on the surface of the PSV-250 steam-water heater, valves, and pipelines. The efficiency was evaluated using a non-contact method as part of a comprehensive study of heat losses through thermal imaging. During the inspection of the heater’s thermal condition, elements with surface temperatures ranging from +60 °C to +224.5 °C were identified, which poses a hazard from an occupational safety perspective. To prevent burns to maintenance personnel and reduce heat losses that lower the efficiency of thermal equipment, these surfaces must be insulated. To address the identified issues, it is recommended to install special removable insulation or apply a thermal insulation coating based on a liquid ceramic composite material.
