Фізичний аспект термічної обробки Шламів ТЕС У технології утилізації у будівельній галузі
The author has considered the physics modeling of the sewage sludge drying treatment at a thermal power plant in conditions of low-temperature mode operation, and with much attention paid to the mass transfer. The heat transfer equation was not considered for the observable diffusion coefficient and constant temperature as a convection component of heat transfer while sewage sludge drying is much lower than the conductive one. Theoretical study of physics of sewage sludge drying has shown that substance drying time does not depend on the geometrical configuration of the object treated but on its peculiar features (material layer thickness, radius) and physical parameters (the moisture diffusion coefficient, the moisture concentration in the material and in the drying agent). The analytical expressions obtained through the physics modeling of thermal dewatering of sewage sludge at a thermal power plant can be used in practice of engineering assessment of substance drying time with no technical parameters of the dryers factored in.
