TL;DR: In this article, the authors proposed to shorten regeneration time by further heating low purity nitrogen for regenerating an adsorber heated by feed air on the outlet side of a feed air compressor of an air liquefying separator.
Abstract: PURPOSE: To shorten regeneration time by further heating low purity nitrogen for regenerating an adsorber heated by feed air on the outlet side of a feed air compressor of an air liquefying separator. CONSTITUTION: At first, feed air is compressed by an air compressor 1. Then, the compressed air exchanges its heat with low temp and, low purity gaseous nitrogen separated by liquefaction from an air liquefying separator 6 in a heat exchanger 2. The cooled air is sent through a water cooling column 3 to an adsorber 4 in which moisture and carbon dioxide in the air are eliminated and removed. Then, liquefying separation of the air is performed in the air liquefying separator 1. On the other hand, the low purity gaseous nitrogen subjected to heat exchange in the heat exchanger 2 is further heated in a regenerating gas heater 5 and sent to the adsorber 4, and after regeneration is performed there, it is discharged to the outside. In this way, when the adsorber is regenerated, the low purity nitrogen is used as a refrigerant for the heat exchanger. COPYRIGHT: (C)1995,JPO

TL;DR: In this paper, a failsafe control of a gas heater is described, where one sensor is mounted directly in the flue and the other behind the baffles, to monitor any flow out of the side vents.
Abstract: One sensor (14) is mounted directly in the flue and the other (17) behind baffles, to monitor any flow out of the side vents in the flue, e.g. to monitor if the flue is blocked. The output signals from the sensors are connected to a processor (16) which operates a shut-off valve in a failsafe control to switch off the burners if the flue is blocked. The sensors are non linear types, with a definite characteristic. They are linked into a potential divider circuit which is monitored by an operational amplifier. A simple logic system including time delay circuits controls the operation of the shut-off valve. ADVANTAGE - Failsafe control of gas heater.
