Title: Thermal feed water deaeration - controls makeup water admission by feed water level with delay relative to steam admission
Inventor: WALTER HERBERT JOSEF
IPC: C02F1/20
Filed: 1975-04-07
Abstract: In a system for thermal deaeration of feed water for boilers, the make-up water or condensate is fed intermittently into a deaerator on top of the feed water tank where it is heated by steam, deaerated and charged into the feed water tank. The cycle which is controlled by the liquid level in the feed water tank admits steam into the aerator only shortly before make-up water is admitted a and cuts off the steam shortly after the water admission has ended. This system has a high thermal efficiency because the steam consumption is kept to a minimum. The full deaeration effect is attained immediately the supply of make-up water begin and is continued throughout the make-up water admission, including water contained in the deaerator when the water valve has shut.

Title: Drying of gases esp. compressed air - using heat exchanger delivering stream at constant pressure lower than that of supply pressure for instrument system
Inventor: HORST JOHN VANDER
IPC: B01D53/26
Filed: 1975-07-15
Abstract: A heat exchanger with dual gas leads receives wet gas from a high pressure source and conveys it in heat exchanging relationship to a cold, partial stream of the same gas which has already been dried and which emerges from a turbulence pipe. The resulting condensate is separated in a settling chamber, placed downstream of the heat exchanger, before the cooled and dried arriving gas is conveyed to the turbulence pipe input. The hot gas partial stream is lead through a stream contacting section situated downstream of the turbulence pipe, before it is recombined with the cold partial stream arriving from the heat exchanger. The remixed stream is then conveyed through an excess pressure valve which controls the pressure to hold it constant to a predetermined value. This stipulated value is lower than that of the supply pressure for the instrument system. Any gas in excess of the downstream requirements is released into the atmosphere.
