The paper reveals that Solar hybrid power plants have a significant potential for cost reduction when the solar energy is introduced into a gas turbine system. A new secondary concentrator with improved efficiency was designed and built. Based on an inexpensive manufacturing technology, the secondary concentrator geometry was optimized to...
The paper concerns the problem of the influence of non condensing gases air on the condenser performance and on the overall efficiency of the power unit. An efficient method for the air in leakage measurement is proposed. It allows the accurate measurement and monitoring of air in leakage rate in...
This paper deals with analyzing different solutions to accomplish the cooling of the turbine inlet air. Incorporating the latest technological design features, a tailored solution, utilizing an optimal design, shall be achieved. These systems have been designed to be compatible with new construction and existing systems installed today. Due to...
This paper presents the outcomes of computational mechanics applied in the root-cause investigation on blade failures of an auxiliary steam turbine in a domestic power plant, in which cracks were detected at the tenon region on the blades during scheduled outages. This involves the calculated data of the finite-element models...
Life extension for aging power plant steam turbines usually includes reconstructive measures intended not only to prolong their service time and raise their reliability but also to improve their efficiency. An effective way to solve this problem and simultaneously cover the needs in steam for heating and/or industrial purposes is...
A steam power plant partial loading optimal operation is discussed. It is reasonable in the case of all turbosets different from base load operation mode ones. It requires an appropriate algorithm automatically performed of steam turbine control valve sequence. An algorithm aiming to analyze the steam turbine efficiency as a...
Deregulation and increasing demand are creating rapid changes in the global energy market, placing a new premium on efficiency and creating the opportunity to structure new products for the evolving needs. To meet these needs through highly-efficient steam turbines, a new design methodology has been developed that is suitable for...
From the view points of environmental load and thermal efficiency, a gas turbine cogeneration system using the technologies of steam injection and two-stage combustion has been proposed. In this system, all steam which is generated in a waste heat recovery boiler is injected into the first stage combustor, and then...
As a promising way to contribute to solving the problems of environment including global warming and the exhaust of energy resources, a gas turbine combined cycle which enables us to obtain the high thermal efficiencies has attracted a great deal of attention. The paper deals with a new gas turbine...
The efficiency of conventional boiler/steam turbine fossil power plants is a strong function of the steam temperature and pressure. The main enabling technology is the development of stronger high temperature materials, capable of operating under high stresses at ever increasing temperatures. Recently EPRI performed a state-of-the-art review of materials technology...
A hybrid power generating and refrigerating cycle with ammonia-water mixture is proposed in the paper. An AWM turbine cycle and a single-effect ammonia-absorption refrigeration cycle are connected to expand the availability of ammonia-absorption refrigerating cycle. To reduce the heat of rectification ammonia-rich liquid is fed from the AWM turbine cycle....

face=+Bold; The ability to detect contaminated feedwater or steam before it can corrode the internals of a turbine or HRSG and cause a forced outage is worth millions. One knock against cation conductivity monitoring--still the most common technique for the early detection of contamination--is the difficulty of interpreting conductivity...
