EXPOSED CLOSED-CIRCUIT STEAM HEATING SYSTEM Russian patent published in 1999 - IPC

FIELD: heating of rooms. SUBSTANCE: system includes steam boiler with heater and condensation riser with hose at the top; they are made in form of separate reservoir partially filled with water and interconnected in area of partitions dividing these reservoirs, dehumidifier for air escaping from system, heat release part at return of condensate by gravity and dry condensate line made in form of loop and temperature or moisture sensor located in lower portion of return pipe line. Reservoir are interconnected by means of pipe line whose length is comparable with thickness of partitions fitted between them and inclined downward from boiler reservoir. Provision is made for high level limit in reservoirs when heater is inoperative. Low portion of hole communicating the air space of reservoir with atmosphere is made at height of maximum level of water in this reservoir when heater is in operation. provision is made for transfer of heat from supply pipe line to return pipe line. Heater of reservoir - steam boiler - has power exceeding thermal power of heating system. EFFECT: enhanced reliability. 2 dwg
