We can provide you gas turbine generator sets in the form of combined cycle gas turbine power plant, in which the exhausted gas from the gas turbine can be transferred to power through the added equipments of recovery boiler and steam turbine. Co-generation gas turbine power plant is composed of a recovery boiler to utilize the high temperature exhausted gas from the gas turbine into steam. The common capacity of the gas turbine power plants from us range from 2MW, 10MW, 20MW, 38MW, 50MW, 135MW and their combination of your required capacity. The applied technologies is of compatible of Siemens and GE and even Chinese innovated ones from aero-space industries. Here we just provide 2mw, and 10mw unit capacity as example for introduction due to their not so articled in our catalogue.
