Energy analysis of heat recovery plants

Abstract This article discusses one of the most typical heat-using processes - the drying process. The selection and assessment of drying units is carried out according to various parameters, however, the clearest idea of the suitability of the dryer for drying material with known properties and its energy characteristics is given by the analysis of the dryer operation, based on the heat technology principles of the design of the technological process under which a characteristic set is taken thermal, hydrodynamic, constructive and other conditions for organizing the technological process of drying materials. Comparison of the energy efficiency of a number of dryers, carried out according to the described technique, taking into account the costs of creating and maintaining the required hydrodynamic conditions in the working chamber of the drying apparatus, referred to the unit volume of the chamber, taking into account the separation of the dried material and cleaning the spent heat carrier.
