Abstract
In a steam-heating apparatus in which a heating section (2) formed in a heat exchanger (1) is connected to a steam supply pipe (3) for receiving supply of heating steam and connected also to a condensate recovering unit (6) for discharging condensate produced as a result of heating, the apparatus includes a steam ejector (5) including a suction chamber (13) connected to the heating section (2) and an inlet for receiving supply of the steam. When the temperature of the heating section (2) or between the heating section (2) and the condensate recovering unit (6) is dropped by a predetermined value, steam is supplied from the steam supply pipe (3) to the inlet of the steam ejector (5) and gas in the heating section (2) is sucked into the suction chamber (13) of the steam ejector (5).
Claims5
A steam-heating apparatus in which a heating section formed in a heat exchanger is connected to a steam supply pipe for receiving supply of heating steam and connected also to a condensate recovering unit for discharging condensate produced as a result of heating, the apparatus comprising:
- a steam ejector including a suction chamber connected to the heating section and an inlet for receiving supply of the steam;
- wherein the steam ejector is actuated in response to a drop in the temperature of the heating section by a predetermined value to cause gas in the heating section to be sucked into the suction chamber of the steam ejector.
