thermal power plants - Opis:
- The studies of the ultimate thermal flows have been carried out in metallic and poorly heat-conducting porous structures, which operate when gravitational and capillary forces act jointly and cool various devices of thermal power plants in order to create a scientific methodology. The mechanism of destruction of metal vaporizing surfaces and poorly heat-conducting coatings of low porosity made of natural mineral media (granite) has been described on the basis of the problem of thermoelasticity and experimental data. Thermal flow dependences on time of their action and depth of penetration of temperature perturbations were identified based on analogy. Capillary-porous systems have high intensity, heat transport ability, reliability, compactness. The results of calculations and experiment showed that the maximum thickness of the particles that detach under the influence of compression forces for granite coatings is (0.25÷0.3).10-2 m. Sections of compression curves that determine the detachment of particles with dimensions of more than 0.3×10-2 m for large thermal flows and short feed times, are screened by the melting curve, and in the case of small thermal flows and time intervals – the expansion curve.
