Micro gas turbine designed to limit heat losses therefrom

A micro gas turbine comprising:

• a compressor configured to take in and pressurize gas;
• a combustor configured to:
• take in pressurized gas from the compressor;
• and
• generate hot gas on the basis of fuel combustion;
• a turbine configured to take in and expand hot gas generated by the combustor;
• a generator mechanically coupled to the turbine and configured to generate electric power on the basis of mechanical power;
• a controller configured to control operation of the micro gas turbine;
• a valve mechanism which is associated with an inlet path to the compressor, the valve mechanism comprising a valve and a connection piece having three connection areas;
• a cabinet accommodating at least the compressor, the combustor and the turbine, the cabinet is connected to a respective one of the connection areas of the connection piece;
• and
• a purging mechanism configured to purge an interior of the cabinet by supplying air to the interior of the cabinet;
• wherein the valve mechanism is controllable by the controller to open the inlet path of the compressor:
• to the interior of the cabinet for enabling the compressor to take in air from the interior of the cabinet;
• and
• to an exhaust connected to another respective one of the connection areas of the connection piece and associated with the turbine for enabling the compressor to take in exhaust gas from the turbine;
• and
• wherein the compressor is connected to another respective one of the connection areas of the connection piece through the valve.
