The World

The profits that can be gained by use of inlet air cooling on gas turbines has been recognised for quite some time now and the systems installed throughout the world have shown the users in the gas turbine field that cooling indeed can be used to boost power at times when the ambient temperature reaches or exceeds the ISO rating temperature of the gas turbine. Drawback however being that the initial investment asked of the gas turbine user is rather large thus only justifying a cooling system in regions where the outdoor temperatures exceed the ISO rating time and again due to the climate in that region. Lately gas turbine users in colder climates have become interested in power augmentation during their short summer, however there is no justification for an investment like necessary when installing one of the presently available systems on the market. As the question reached us from more and more of our clients it stimulated us to go out and search for a low-investment solution to this problem. This resulted in the world’s first low pressure gas turbine inlet cooling system.

Two-stage Gas turbine unite (GTU) inlet air cooling by absorption lithium-bromide chiller (ACh) to the temperature 15 °C and by refrigerant ejector chiller (ECh) to 10 °C through utilizing the turbine exhaust gas heat for changeable ambient air temperatures and corresponding heat loads on the air coolers for the south Ukraine climatic conditions is analysed. An excessive refrigeration capacity of combined absorption-ejector chiller (AECh) exceeding the current heat loads and generated at decreased heat loads on the air coolers at the inlet of GTU can be used for covering increased heat loads to reduce the refrigeration capacity of AECh. The GTU inlet air cooling system with an ambient air precooling booster stage and a base two-stage cooling air to the temperature 10 °C by AECh is proposed. The AECh excessive cooling capacity generated during decreased heat loads on the GTU inlet air coolers is conserved in the thermal accumulator and used for GTU inlet air precooling in a booster stage of air cooler during increased heat loads. There is AECh cooling capacity reduction by 50% due to the use of a booster stage for precooling GTU inlet ambient air at the expense of an excessive cooling capacity accumulated in the thermal storage.

The operation of gas turbine unites significantly depends on the ambient air temperature at the inlet, and the higher it is, the greater the specific fuel consumption is spent for the production of a unit capacity (mechanical/electrical energy), and, accordingly, the more harmful substances are removed to the atmosphere with exhaust gases. To reduce the negative impact of unproductive fuel consumption during the operation of gas turbine units at elevated ambient temperatures, the inlet air cooling is applied. The paper studies the ecological efficiency of gas turbine unite inlet air cooling, taking into account the variable climatic operation conditions for regions with different climatic conditions over a period of five years (2014-2018): temperate climate of Ukraine (on the example of cities Sumy and Ternopol) and the subtropical climate of the PRC (cities Beijing and Nanjing). The annual reduction in emissions of carbon dioxide CO2 and nitric oxide NOX was chosen as indicators for assessing the environmental effect of air cooling. It has been shown that deeper cooling gas turbine unite inlet air to 7...10 °C provides almost a half to two times greater reduction in specific fuel consumption, respectively, and harmful emissions compared with traditional cooling to 15 °C by the most widespread absorption lithium-bromide chillers, and for the temperate climate of Ukraine the relative effect is much greater than for the subtropical climatic conditions of the PRC. Reducing carbon dioxide CO2 over five years for the PRC climate when cooling air to 10 °C is approximately more than 500 t, and for Ukraine – more than 240 t, and NOX nitric oxide – about 3.5 t for China and 1.6 t for Ukraine, while with traditional cooling to 15 °C: more than 300 t for China, and for Ukraine about 120 t, and nitric oxide NOX – about 2 t for China and 0.7 t for Ukraine. Based on the results of a rough assessment of the environmental effect of cooling the ambient air at the inlet of gas turbine units, in the temperate climate of Ukraine, deep cooling of the air is especially advisable, which provides almost twice the effect compared with traditional cooling to 15 °C.

The processes of the gas turbine inlet air cooling by exhaust heat conversion chillers, which utilizing the gas turbine exhaust gas heat, converting it into cold were analyzed. The use of two-stage air cooling has been investigated: to a temperature of 15°C – in an absorption lithium-bromide chiller and below to a temperature of 10°C – in an ejector chiller as stages of a two-stage absorption-ejector chiller. To simulate air cooling processes, the program "Guentner Product Calculator", one of the leading manufacturers of heat exchangers "Guentner", was used. The possibility of using the accumulated excess refrigeration capacity of a combined absorption-ejector chiller, which is formed at reduced current heat loads on air coolers at the gas turbine inlet, to cover the refrigeration capacity deficit arising at increased heat loads due to high ambient air temperatures has been investigated. The refrigeration capacity required to the gas turbine inlet air cooling was compared to an excess refrigeration capacity which excess of the current heat load. The considered air cooling system provides pre-cooling of air at the gas turbine inlet by using the excess refrigeration capacity of the absorption-ejector chiller, accumulated in the cold accumulator, to provide the required refrigeration capacity of the air pre-cooling booster stage. The simulation results proved the expediency of the gas turbine inlet air cooling using the accumulated excess refrigeration capacity of the combined absorption-ejector chiller. The proposed solution reduces by about 50% the design refrigeration capacity and, accordingly, the cost of the installed absorption lithium-bromide chiller, which acts as a high-temperature stage for cooling the ambient air at the gas turbine inlet.
