METHOD FOR OPERATING GAS GENERATORS IN TANDEM

摘要

A gas generating system (S) has a plurality of product gas generating modules ( 18 ) each of which comprises a plurality of molecular sieve beds (bed 1 , bed 2 ) generating a product gas acting in a repetitive cycle with each cycle having a period of the cycle with peak product gas flow ( 106 ). A manifold ( 52 ) combines the product gas from the plurality of modules ( 18 ). The processor ( 58 ) generates a control signal that is communicated to the gas generating modules ( 18 ) such that the peak product gas flow period ( 106 ) of the repetitive cycle of the modules ( 18 ) is adjusted in response to the control signal. The processor ( 58 ) causes the peak period ( 106 ) for the modules ( 18 ) to be timed across the repetitive cycles in a controlled distribution.
