Features of Low-Grade Steam Application in Heat Supply Systems

The paper considers the possibility of the energy efficiency increase at the enterprises by implementing the low-grade steam compressing. The energy costs for the compression of low-grade steam process were analyzed. The scheme of the technological process of compression of low-grade steam is proposed. The graphs of the dependence of the productivity coefficient were built. The system was also compared with steam mechanical compression and a boiler room to ensure the thermal needs of the consumer. The results of comparing energy costs expressed in fuel equivalent for consumers of hot water from a boiler and from a steam compression system of an enterprise are presented. It was revealed that the introduction of this technology in industrial enterprises leads to the saving of primary fuel.
