Condensate draining system for temperature regulated steam operated heat exchangers

Patent ·
OSTI ID:5718599
A condensate draining system is described for a temperature regulated, steam operated heat exchanger having a steam compartment, a steam inlet and a steam condensate outlet. The draining system consists of: a buffer tank; a first condensate drainage pipe extending from the heat exchanger to the buffer tank; a condensate outlet positioned in the condensate drainage pipe; air venting means connected to the condensate outlet of the heat exchanger, the air venting means including a gas control pipe extending from an upper part of the buffer tank to the heat exchanger steam condensate outlet to permit introducing directly into the steam compartment of the heat exchanger a non-condensing gas having a higher specific gravity than that of steam within the heat exchanger and a higher pressure than atmospheric pressure, and a non-return valve positioned in the gas control pipe; a condensate collection pipe positioned above the buffer tank; and a second condensate drain pipe extending from the condensate collection pipe to a lower part of the buffer tank.
