A thermodynamic process of power generation has been developed for a gas turbine, a steam turbine, and a compressor, supported by adiabatic expansion or compression processes. Recently, the possible inlet temperature of gas turbines has been increased to 1500°C or more, and the inlet temperature of steam turbines also has been increased to 650°C. At these high-temperature conditions, turbine no...

The ultra-supercritical (USC) double-reheat technology is an immediate area of research focus in China, since the thermal efficiency USC unit higher than single-reheat unit. parameters and capacity China have made major breakthroughs, units are as high 47–48%, which highest world. boiler one most important devices for unit, design concept precision a vital effect on operation power station. dif...

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...

BACKGROUND An open-irrigated radiofrequency (RF) ablation catheter was developed to measure contact force (CF). Three optical fibers measure microdeformation of the catheter tip. The purpose of this study was to (1) validate the accuracy of CF sensor (CFS) (bench test); and (2) determine the relationship between CF and tissue temperatures, lesion size, steam pop, and thrombus during RF ablation...

Making potable water through desalination plants is a very important process in Iran where clean water is highly required. On the other hand, large amount of fossil fuel sources leads to the development of gas turbine power plants all over the country. Furthermore, Persian Gulf in the south and Caspian Sea in the north could be the main sources for supplying potable water in water scarcity area...

The Australian National University has a 400m Paraboloidal dish solar concentrator system, informally named “the Big Dish” that produces superheated steam via a receiver mounted monotube boiler. The system, (shown in Figure 1) which is the worlds largest was constructed in 1994. This paper describes the results of the latest experimental tests plus associated system performance modelling. The s...

A model-based controller (Dynamic Matrix Control) and an intelligent controller (Fuzzy Logic Control) have been designed and implemented for steam temperature regulation of a 300 MW thermal power plant. The temperature regulation is considered the most demanded control loop in the steam generation process. Both proposed controllers Dynamic Matrix Controller (DMC) and Fuzzy Logic Controller (FLC...
