Turbine system for natural gas and steam operating in a semi-open cycle.

摘要

The system, which comprises at least one combustion chamber (1), an expansion turbine) 2), an air compressor (3) Dragged by turboexpander (2) and means for coupling the expansion turbine (2 ) to at least one external receiver (4) mECHANICAL POWER, further comprising means for injecting water constituting a ballast TERMICO in the combustion chamber, STAYING THE AMOUNT OF COMPRESSED AIR USED NEAR THE AIR SHOULD cOMBUSTION FOR cOMBUSTION stoichiometric. These means ADDITIONAL injection comprise: A) a heat exchanger MASS AND HEAT (7) between the combustion products straight out of a RECUPERADOR condensate (6) PLACED IN THE COURSE OF THE EXHAUST TURBINE EXPANSION (2) ATMOSPHERIC AIR ENTERING TO PERMIT PRIOR air humidification before its entry into the compressor (3). B) devices (13, 14; 15, 16) for injecting water and liquid water between the outlet of air compressor (3) YLA burner inlet (19) or the combustion chamber (1) AFTER AREA FIRE AND BEFORE THE FIRST Shovels turboexpander (2), pRODUCED THE WATER VAPOR iNJECTED BY A COLLECTOR HEATER STEAM (5) ARRANGED ON EXHAUST IMMEDIATELY LEAVING THE turboexpander (2) , and liquid water obtained from recycled CONDENSED WATER PRODUCED IN THE RECOVERY OF CONDENSATION (6).
