OPEN CLOSED-CIRCUIT STEAM-HEATING SYSTEM AND METHOD FOR CYCLIC OPERATION OF SYSTEM Russian patent published in 1995 - IPC

FIELD: steam-heating system. SUBSTANCE: steam-heating system has steam boiler and condensate uptake, which are made in the form of sections of vessel positioned in horizontal plane. Vessel is divided by vertical wall. Pipeline for communicating steam boiler and condensate uptake is extending through lower part of dividing wall. Dehumidifier for dehumidifying of air exiting from the system is mounted in upper section of condensate uptake. Overflow opening is positioned in sidewall of section above opening, through which pipeline is extending for limiting water level in vessel. Heat-emitting part of system is made in the form of loop having feeding and return pipelines, which are inclined respectively towards boiler and condensate uptake, with heating devices being positioned above one of pipelines. Temperature and humidity detectors are secured at the end of return pipeline. Heater of boiler has heat power exceeding that emitted by heating system. EFFECT: increased efficiency and enhanced reliability in operation. 4 cl, 3 dwg
