gas turbine requires lot of cooling water
gas turbine is capable of rapid start up and loading
gas turbines have flat efficiency at part loads
gas turbines have high standby losses and require lot of maintenance
reduction of speed of incoming air and conversion of part of it into pressure energy
compression of inlet air
increasing speed of incoming air
lost work
closed cycle
open cycle
both of the above
closed/open depending on other con-siderations
h.p. compressor L connected to h.p. turbine and l.p. compressor ot l.p. tur-bine
h.p. compressor is connected to l.p. turbine and l.p. compressor is con-nected to h.p. turbine
both the arrangements can be employed
all are connected in series
