Embodiment 1

[0030] The organic droplet nozzle adopts an array grid structure on the spraying device 5. Multiple nozzles 6 are placed on the spraying device 5. The diameter of the organic droplet is calculated according to the following formula, and the nozzle model is selected according to the calculated diameter of the organic droplet.

[0031] d = S V k π

[0032] Among them, d is the average droplet diameter of the atomized organic droplet, S is the axial length of the compressor 1, V is the flow velocity of the air at the inlet of the compressor 1, k is the evaporation coefficient of the organic droplet, and π is the pi constant .

[0033] When the turbine is working, the air is first sucked into the internal circulation system of the turbine by the compressor 1 through the intake chamber. At the inlet of the turbine and upstream of the compressor 1, an injectio...

Abstract

The present invention discloses a wet compression method for small and medium size turbines, belonging to the technical field of aircraft power machinery, power output machinery, and power generation machinery. According to the present invention, at the inlet of the turbine, and the upstream of a compressor, a jetting device is adopted for jetting atomized organic droplets in the moving air that enters the small and medium size turbine in a direction perpendicular to the air moving direction; the diameter of the organic droplets is calculated according to the following formula: wherein, d is the average droplet diameter of the atomized organic droplets, S is the axial length of the compressor 1, V 1 is the air flow rate at a compressor inlet, kappa is the evaporation coefficient of the organic droplets, and pi is the pi constant. The method of the present invention has a wide application range, improves the efficiency of the turbine thermal cycle, increases the output power of the turbine, broadens the application range of wet compression technology, and reduces requirements for jet technology, wherein the droplet particle diameter can be larger than a sprayed water droplet.

Description

technical field [0001] The invention belongs to the technical fields of aircraft power machinery, power output machinery and power generation machinery, and in particular relates to a wet compression method for small and medium-sized turbines. Background technique [0002] As we all know, spraying water into the working medium of a large gas turbine can increase the output power of the gas turbine. This method is applied in the field of gas turbine power generation, and is generally called wet compression technology. The reasons for increasing the output power are generally summarized as follows: first, the cooling effect reduces the power consumption of the compressor due to the increased water evaporation; . [0003] In industry, large gas turbines for power generation generally participate in the compression process in the form of water spray atomization and the formation of small droplets. Due to the long axial dimension of large gas turbines, the flow rate in the comp...
