Abstract
An apparatus (1) is provided for compressing gas, the apparatus comprising a conduit (3) provided with a non-return inlet valve (10) arranged at the upstream inlet (5) end of the conduit (3), a localized ignition source (20) arranged in the conduit (3) downstream of the non-return inlet valve (10), and means (23) for intermittently supplying secondary fluid into the conduit (3) between the non-return inlet valve (10) and the localized ignition source (20).
Claims1
A method of compressing a combustible gas flowing through a conduit having an inlet end and an outlet end being provided with a non-return inlet valve at its inlet end, which method comprises the steps of:
- (a) supplying intermittently a combustible mixture in the conduit downstream of the non-return valve by intermittently supplying an oxidant into the conduit downstream of the non-return inlet valve;
- (b) allowing the combustible mixture to ignite, which ignition yields a high pressure wave front closing the non-return inlet valve and pushing gas out of the outlet end of the conduit and a low pressure wave front;
- and
- (c) allowing the non-return valve to open on arrival of the low pressure wave front to allow gas to enter into the conduit.
