APPARATUS AND METHOD FOR ECONOMIC USE OF EXCESS COMPRESSED AIR WHEN FIRING LOW CALORIC-VALUE GAS IN A COMBUSTION GAS TURBINE

摘要

A system and method are described for transferring excess air from the compressor of a combustion-gas turbine having a paired compressor and expander, to at least one separate combustor where it is mixed with fuel and burned to power at least one non-paired expander. In a preferred embodiment, the non-paired expander is an "off the shelf" unit which can be readily purchased and installed.
