Title: Method for operation of heating boiler house
Inventor: SHARAPOV V I
IPC: F24D3/02
Filed: 1997-04-10
Granted: 1999-09-20
Abstract: FIELD: heat power engineering. SUBSTANCE: according to method, heating water coming from consumers is directed via return pipeline of heating system back to consumers. Temperature of heating water before hot-water boiler is maintained constant by undertaking recirculation of part of water from supply pipeline to return pipeline of heating system. Leakage of heating water is compensated by make-up water which via make-up pipeline is directed to return pipeline of heating system. Make-up water is treated in vacuum deaerator. For this purpose deaerator is supplied with primary water and heating agent through pipelines of primary water and heating agent, and water recirculation is performed through heating agent pipeline, vacuum deaerator and make-up pipeline. Constant temperature of heating water before hot-water boilers is maintained by regulation of water flow rate in pipeline of heating agent of vacuum deaerator. Combined process of heating water recirculation and treatment of make-up water allows for simplification of boiler house arrangement. EFFECT: higher efficiency. 1 dwg
