Vertical combustion gas turbine

Abstract

The invention provides a vertical combustion gas turbine. The vertical combustion gas turbine comprises a combustion gas turbine shell, and a gas compressor, a combustion chamber, a gas turbine, a rotary shaft and non-liquid oil lubricating bearings which are located inside the combustion gas turbine shell, wherein the rotary shaft is arranged in a manner of being vertical to the ground; the pressure machine and the gas turbine are respectively mounted at the two ends of the rotary shaft through the non-liquid oil lubricating bearings; the combustion chamber is located between the gas compressor and the gas turbine; air inlets and air outlets of the gas compressor and the gas turbine are radial air inlets and radial air outlets. According to the vertical combustion gas turbine disclosed by the invention, the vertical installation of an impeller mechanical rotor is realized; the rotor dynamic performance of an impeller machine is improved, the service life of the impeller machine is prolonged, and the reliability of the impeller machine is improved; a flowing medium flows through all parts in a manner of radial air feeding and radial air discharging, so as to reduce the gas flowing swerving loss, realize a high pressure ratio and improve the pneumatic efficiency; an axial pneumatic load is not generated and the axial friction loss is relieved; the mechanical efficiency is improved; the non-liquid oil lubricating bearings are adopted so that the structure is simplified and the axial length of the impeller machine is shortened.

Description

technical field [0001] The invention relates to an impeller machine, in particular to a vertical gas turbine with a rotating shaft arranged upright. Background technique [0002] Turbomachinery is a kind of machine that takes continuous rotating blades as the main body to convert energy between fluid working medium and shaft power. It can be a prime mover or a working machine. The working process of the turbomachinery is a process in which the energy of the fluid or process material (such as powder, particles) and the mechanical energy are converted into each other or the energy transfer between the fluids of different energy. Because in almost all fields of technology and life, it is necessary to perform energy conversion by means of fluids or process materials or to transport fluid media or process materials, so the turbomachinery is a kind of mechanical equipment with a wide range of applications. With the continuous emergence of new technologies, new processes and new m...
