Micro gas turbines fit perfectly with the energy roadmap to 2050: on-site, small scale power generation, combined heat recovery from exhaust gas, offers an opportunity deploy primary saving and pollutant emission reduction. Moreover, their flexibility enables fuel switching natural (NG) carbon-free fuels such as hydrogen ammonia. This study aims explore potential of direct combustion ammonia in...

Performance of a gas turbine mainly depends on the inlet air temperature. The power output of a gas turbine depends on the flow of mass through it. This is precisely the reason why on hot days, when air is less dense, power output falls. The objective here is to assess the advanced systems applied in reducing the gas turbine intake air temperature and examine the merits from integration of the ...

application of cogeneration systems based gas turbine for heat and power production is increasing. because of finite natural energy resources and increasing energy demand the cost effective design of energy systems is essential. cgam problem as a cogeneration system is considered here for analyzing. two new approaches are considered, first in thermodynamic model of gas turbine and cogeneration ...

heat recuperation is often used to improve the overall cycle efficiency of gas turbines. however, generally in small- scale gas turbines, it has a negative effect on turbine inlet temperature, pressure ratio and pressure drops, and thus decreases the overall cycle efficiency. in this paper, a thermodynamic model is performed to evaluate recovered heat as a function of heat exchanger effectivene...

determination of the starter torque-speed diagram is a major task in the design or selection of a proper gas turbine starter. in this paper, the maximum power of the mgt-40 gas turbine starter was calculated based on the dynamics of the rotor, start-up logic, and compressor map. in a recent research, the pressure ratio was assumed as a linear function of the rotor speed and the required starter...

The exhaust gases of gas turbine power plant carry a significant amount of thermal energy that is usually expelled to the atmosphere this causes a reduction in net work and efficiency of gas turbine. On the other hand, the generated power and efficiency of gas turbine plants depend largely on the temperature of the inlet air, So that they both increase as the inlet air temperature decreases. Th...

Biomass is identified as one of the major renewable energy sources for electrical power generation. Heavy duty gas turbine engines are preferred for clean and efficient power generation. An extensive literature survey reveals that the governor droop setting of the heavy duty gas turbines varies from 2 percentage to 10 percentage. But it needs to be optimized for analyzing the dynamic response o...
