In the coming carbon-neutral era, industrial gas turbines (GT) will continue to play an important role as energy conversion equipment with high thermal efficiency and stabilizers of electric power grid. Because transition a clean fuel, such hydrogen or ammonia, main modifications lie combustor. It can be expected that small medium-sized burn fewer inferior fuels, scope cogeneration activities t...

Turbine inlet temperature has continuously increased to improve gas turbine performance during the past few decades. Although internal convection cooling and traditional film have contributed significantly current achievement, advanced schemes are needed minimize coolant consumption maximize efficiency for future turbines. This paper conducts a comprehensive review of effusive blades. First, ba...

An experimental study of hydrodynamics of film cooling is performed by using a single longitudinal slot on a cylindrical model simulated to the leading edge of the gas turbine blade. The model is set up into the test section of an open-circuit induced flow wind tunnel which provides the main flow. The injected air, as a secondary film flow, produced from a high pressure compressor is considered...

Characteristics of high-efficiency gas turbine cogeneration systems using low Btu gas (LBG) are first analysed. Raising the turbine inlet temperature and incorporating a regenerator are both investigated as methouds to improve the efficiency of the cogeneration system (CGS). Taking a gas obtained by pyrolyzing municipal refuse as an example of an LBG, various thermodynamic characteristics of th...

Three combined power and refrigeration system are introduced to compare and analyze for a defined demand and same fuel consumption based on thermodynamic parameters in a 24 hours period. Gas turbine and/or steam turbine are used for power generation and also ejector refrigeration cycle is used to produce cooling. These three systems are named as GER, SER and GSER. The results of three systems a...

Increasing concerns about energy and emissions from fuel consumption in gas turbines has attracted many researchers to protect the environment and reduce pollutants in the world. The main objective of this paper is to investigate the increasing efficiency of three-stroke gas turbine operation based on the technical analysis of the operation of three-axis gas turbine cycles with non-design condi...
