As an clean renewable energy source wind energy is highly regarded by various countries in the world. Wind turbine blade is one of the most important components in wind turbine. It is the key component for receiving wind energy. As turbine size steps up and the size of modern turbine blade increases, condition monitoring and maintenance of blades become more important. Strain detection is one o...

Two power plant schemes that reduce CO2 emission and employ natural gas reforming were analyzed and discussed. The first one integrates natural gas reforming technology for efficiency improvement with an oxy-fuel combined power system (OXYF-REF), with water as the main work fluid. The reforming heat is obtained from the available turbine exhaust heat, and the produced syngas is used as fuel wit...

Power generation using waste-gas is an effective and green way to reduce the emission of the harmful blast furnace gas (BFG) in pig-iron producing industry. Condition monitoring of mechanical structures in the BFG power plant is of vital importance to guarantee their safety and efficient operations. In this paper, we describe the detection of crack growth of bladed machinery in the BFG power pl...

High cycle fatigue failure of turbine and compressor blades due to resonance in the operating frequency range is one of the main problems in the design of gas turbine engines. To suppress excessive vibrations in the blades and prevent high cycle fatigue, dry friction dampers are used by the engine manufacturers. However, due to the nonlinear nature of friction contact, analysis of such systems ...

ABSTRACT Blade failure is a common problem of a steam turbine and it’s failure in-service results in safety risks, repair cost and non operational revenue losses. Thus, the reliability of these blades is very important for the successful operation of a steam turbine. Dynamic analysis of a steam turbine blade in computational environment is carried out in the present work. In order to gain physi...

By making use of a suite of programs for designing profile geometry, cutter geometry and predicting the thermodynamic performance of a twin screw compressor, this paper investigates techniques of obtaining an optimised rotor cutter blade design. The techniques for using different geometric schemes for setting clearances are explained, and the techniques for optimising main manufacturing paramet...

The article presents the results of development proposals to increase safety margin blades and efficiency a single-stage axial flow turbine compressor small-sized turbo-shaft engine being modernized with use multidiscipline optimization methods. Analysis initial version showed that working is significantly lower than required by strength standards. To eliminate problem encountered task blade wa...

In order to achieve the fast load following and safe transient operation of Solid Oxide Fuel Cell-Gas Turbine hybrid system, a novel control approach by combining multi loops with coordinated protection is proposed in this work. The can adjust behavior parameters on-line avoid undesired faults, such as compressor surge, reformer carbon deposition, fuel cell thermal crack turbine blade overheat....
