Rotary knocking gas turbine

Abstract

The invention discloses a rotary knocking gas turbine. The rotary knocking gas turbine comprises a gas inlet passage, a diffusion section and a gas storage chamber which are connected in sequence from left to right, wherein a gas compressor is arranged at the downstream of the gas inlet passage; a rotary knocking combustion chamber is positioned at the right end of the gas storage chamber, the right end of the rotary knocking combustion chamber is connected with a mixing chamber, a turbine and an exhaust pipe in sequence, a plurality of nozzles are annularly arranged on the left end face of the rotary knocking combustion chamber at equal intervals, and six ignition plugs are uniformly arranged on the circumference of the rotary knocking combustion chamber; an air passage and a combustion passage are arranged on each nozzle, the gas storage chamber is communicated with the rotary knocking combustion chamber through a gas supply passage and the air passages of the nozzles, and the mixing chamber is communicated with the gas storage chamber through a gas escape bypass; a rotor is arranged between the gas compressor and the turbine, the gas compressor of a rotating component of the gas turbine and the turbine are connected with a casing of a static bearing component of the gas turbine through two bearings, and one end of the rotor is led out from the gas exhaust pipe. When the rotary knocking gas turbine is used, the leading-out end of the rotor is connected with a generator assembly through a speed changer.

Description

【Technical field】 [0001] The invention relates to a gas turbine, in particular to a rotating detonation gas turbine for ships and industries. 【Background technique】 [0002] Combustion is an indispensable key link in the release of fuel energy in gas turbines. There are many forms of combustion. According to the characteristics and methods of flame self-propagation, it can be divided into two types: slow combustion and detonation combustion. Slow-flame combustion is the acceleration of the reaction caused by the temperature rise of the unburned mixture through heat conduction (or the transfer of free atoms and free radicals to the unburned mixture due to thermal diffusion and thermal radiation to produce a chain reaction), thereby making the flame The leading edge continues to advance into the unburned mixture, and the flame surface of the slow-burning combustion is usually called a slow-burning wave. Due to the limitation of the temperature transfer mode of the slow-burning...
