GAS TURBINE INTAKE AIR COOLING METHOD AND GAS TURBINE INTAKE AIR COOLING SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve cooling efficiency while suppressing inflow of mist to a downstream side.;SOLUTION: A gas turbine intake air cooling method includes: analyzing the quantity of mist in a downstream part of a simulation part in an air duct shape modelling a gas turbine intake air cooling device of an actual machine; adjusting a water spray amount of a nozzle part for simulation in such a manner that the quantity of mist in the downstream part of the simulation part becomes equal to or less than a predetermined value; varying a temperature and a humidity of air at a position at an upstream side of the nozzle part for simulation, thereby acquiring a relationship of the temperature of air at the position at the upstream side of the nozzle part for simulation, the humidity of air at the position at the upstream side of the nozzle part for simulation and the water spray amount of the nozzle part for simulation which makes the quantity of mist in the downstream part of the simulation part equal to or less than the predetermined value; and setting the water spray amount of a nozzle part for actual machine based on a temperature and a humidity of air at an upstream side of the nozzle part for actual machine in the gas turbine intake air cooling device and the relationship.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
