Marine gas turbine inlet air temperature adjusting system and adjusting method thereof

Abstract

The invention relates to a marine gas turbine inlet air temperature adjusting system. The marine gas turbine inlet air temperature adjusting system comprises an air inlet heat exchanger installed at an inlet of a gas turbine air inlet system, and a fresh water circulating cabinet, a fresh water inner circulating pump, a fresh water outer circulating pump, a seawater cooler and a refrigerant water cooler which are arranged in a cabin, a first water outlet of the fresh water circulation cabinet is connected with a fresh water inlet of the seawater cooler through the fresh water inner circulation pump; a fresh water outlet of the seawater cooler is connected with a first water inlet of the fresh water circulation cabinet; a second water outlet of the fresh water circulation cabinet is connected with a fresh water inlet of a refrigerant water cooler through a fresh water outer circulation pump, a fresh water outlet of the refrigerant water cooler is connected with a water inlet cavity of the air inlet heat exchanger, and a water outlet cavity of the air inlet heat exchanger is connected with a second water inlet of the fresh water circulation cabinet; a bypass pipeline is arranged between a fresh water inlet and a fresh water outlet of the refrigerant water cooler; the fresh water circulation cabinet is provided with an air inlet connected with a ship steam system. According to the marine gas turbine inlet air temperature adjusting system, the air inlet temperature of the gas turbine can be reduced in a high-temperature environment, and the air inlet temperature of the gas turbine can be increased in a low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of gas turbine intake system design in a ship power system, in particular to a marine gas turbine intake temperature adjustment system and an adjustment method thereof. Background technique [0002] Due to the gas turbine's small size, light weight, high degree of automation, and strong mobility, it has become more and more important in the ship power system. change. In addition to being used as a ship propulsion power device, the gas turbine can also be used as the prime mover of the generator set. The electric energy generated is not only used for the motor to propel the ship, but also supplies power for other electrical equipment on the ship, so as to realize the comprehensive and efficient utilization of electric energy. [0003] However, the output power and thermal efficiency of the gas turbine are affected by the intake air temperature. In different seasons or in the marine environment, the air tempe...

Problems solved by technology

However, before the start of the gas turbine and at low operating conditions, the intake system may still freeze due to the inability to obtain high-temperature compressed air, especially the intake louvers, and there is even a risk of blockage
