FIELD: heat power engineering. SUBSTANCE: invention relates to heat systems of heat power stations. Electric station considered as prototype uses network heating plants only during heating sea sons. However, during summer period, at no heat demand, network heating plants are cut out with resulting downtime of equipment. Proposed invention makes it possible to prevent downtime of equipment owing to the fact two pipelines with shutoff and control devices connecting lines of main condensate and heating system water located before and after heaters supplied with steam of one steam extractions are included additionally into electric station system. EFFECT: increased economy of heat power station owing to use of idling heaters. 1 dwg |
