Abstract
Abstract An oxygen enriched gas supply arrangement for combustion purpose'which is so arranged that, by supplying air to a selective air permeating membrane cell, flow rate and/or oxygen concentration of the oxygen enriched gas passed through the selective gas permeating membrane cell are controlled to predetermined conditions required for the combustion. The arrangement further includes devices for maintaining humidity in the oxygen enriched gas thus obtained at a constant level and for removing pulsation in it, thus being particularly suitable as an air supply source for various combustion equipment and apparatuses.

Claim 2
Dependent Claim
58 words
An oxygen enriched gas supply arrangement which comprises a housing, a selective gas permeating membrane cell provided in said housing, means for supplying air to said selective gas permeating membrane cell for obtaining oxygen enriched gas therethrough, and means for controlling flow rate and/or oxygen concentration of oxygen enriched gas obtained through said selective gas permeating membrane cell..
Claim 3
Dependent Claim
36 words
An oxygen enriched gas supply arrangement as claimed in Claim 1, further comprising means for controlling humidity of said oxygen enriched gas to a predetermined value, and means for removing pulsation in said oxygen enriched gas.
Claim 4
Dependent Claim
93 words
. An oxygen enriched gas supply arrangement as claimed in Claim 2, wherein said means for controlling the humidity of the oxygen enriched gas to the predetermined value is of a humidity eliminating device including a structure formed by a material absorbing and penetrating water and another material having favorable heat conductivity which are caused to closely adhere to each other, said structure being arranged to contact, at its one edge, the oxygen enriched gas or condensate in said oxygen enriched gas, and at its other edge, atmospheric air or nitrogen enriched gas.
Claim 5
Dependent Claim
34 words
An oxygen enriched gas supply arrangement as claimed in Claim 2, wherein said means for removing the pulsation in the oxygen enriched gas is of a tank for storing therein the oxygen enriched gas.
Claim 6
Dependent Claim
69 words
An oxygen enriched gas supply arrangement as claimed in Claim 1, wherein said selective gas permeating membrane cell further includes a main membrane cell and. an auxiliary membrane cell, said flow rate and/or oxygen concentration of the oxygen enriched gas to be obtained through said selective gas permeating membrane cell being arranged to be controlled by controlling flow rate of the oxygen enriched gas through said auxiliary membrane cell.
Claim 7
Dependent Claim
23 words
An oxygen enriched gas supply arrangement as claimed in Claim 5, wherein said auxiliary membrane cell further includes a plurality of membrane cells.
Claim 8
Dependent Claim
49 words
