Combined circulating system of micro gas turbine, transportation means and charging system

A combined circulating system of a micro gas turbine, comprising the micro gas turbine, a heat exchange unit, a circulating water tank, a piston engine, and a power generating apparatus,

• wherein the micro gas turbine is provided with a regenerator;
• an exhaust port of the regenerator is connected with an air inlet of the heat exchange unit to provide a heat source to the heat exchange unit;
• an exhaust port of the heat exchange unit is led to an atmosphere, a water inlet of the heat exchange unit is connected with a water outlet of the circulating water tank, and a steam outlet of the heat exchange unit is connected with the piston engine to enable a working steam to enter the piston engine to push the piston engine to produce work;
• the piston engine is connected with the power generating apparatus to drive the power generating apparatus to generate electricity;
• the circulating water tank is connected with the piston engine to recover water or a water-vapor mixture converted after the working steam produces the work.
