Steam turbines employed in the sugar industry require high thermodynamic efficiency and absolute reliability. The AEG-KANIS Steam Turbine Company, situated in Nuremberg, West Germany, and for many years a supplier to the South African industry, developed such turbines based on 30 years of experience with turbines for all industrial purposes. A special feature of these typical turbines used for ...

In cooperation with Rolls-Royce and Lund University, a combined cycle power plant was modelled, simulated and optimised in the new software framework, the GTPOM tool, developed through the recent EC FP5 programme. The goal was not only to calibrate its component models but also to show how this new tool can be used. This paper presents the gas turbine and combined cycle whole plant modelling an...

For the participation of the steam power plants in regulating the network frequency, boilers and turbines should be co-ordinately controlled in addition to the base load productions. Lack of coordinated control over boiler-turbine may lead to instability; oscillation in producing power and boiler parameters; reduction in the reliability of the unit; and inflicting thermodynamic tension on devic...

With the increase in thermal power capacity, ultra supercritical units have become the mainstream of power industry. At the same time, with the improvement of the steam parameters and the lengthening of shafting, the production of steam flow excited vibration is frequent in the ultra supercritical units, which may seriously affect the reliability of the unit. This paper has taken steam flow exc...

In a molten-salt solar power tower, liquid salt at 290oC (554oF) is pumped from a ‘cold’ storage tank through the receiver where it is heated to 565oC (1,049oF) and then on to a ‘hot’ tank for storage. When power is needed from the plant, hot salt is pumped to a steam generating system that produces superheated steam for a conventional Rankinecycle turbine/generator system. From the steam gener...

In this paper combined Brayton–Rankine cycle was mathematically simulated. In the Matlab program package an adequate numerical procedure has been developed to determine the maximum thermal efficiency of the combined cycle limited by the temperature of exhaust gases at the entrance of the gas turbine and the temperature of the condensation of water vapour in the steam condenser. Furthermore, add...

Power station steam turbine stage flow characteristics show the Corresponding relationship between pressure and flow rate, which is the important research foundation for analysis of steam turbine performance and the further optimization analysis of unit. Based on strict theory analysis, this article obtained two important key characteristic coefficients such as the capacity of flow coefficient ...

Creep resistant alloys designed for power plant applications like thick section boiler components, steam lines, turbine rotors and turbine castings must be reliable over long periods of time in sever environments. Besides high creep strength these materials must exhibit also other properties, i.e. good corrosion and crack resistance as well as good weldability. The environmental impact and econ...

The commissioning of a control system can give fresh insight into the operating characteristics of the driven machinery and thus provide both supplier and user with essential data on the desired control specification for the turbine driver. It can also provide a better understanding of the interaction of the power characteristics of driver and driven machines and the capabilities of the steam t...

An application of development of fault tolerant control (FTC) system for condensation turbine has been presented in the paper. The tolerance of instrument faults has been achieved by the use of functional redundancy which consists in performance of appropriate changes in the operation manner of the faulty system. The method of fuzzy neural networks (FNN) has been used for fault detection and is...
