In recent years, reliability, availability, and capacity have become critical issues in power plants industries. It is also becoming a challenge to meet the demand without the expansion of aged power plants. This paper presents availability analysis of the power generation systems in cogeneration plants situated in Kuwait. Furthermore, an overview of the current situation about Kuwait power pla...

This paper presents recent operating results of Coal Tech s second generation, air cooled, slagging coal combustor, and its application to power plants in the 1 to 20 MW range. This 20 MMBtu/hour combustor was installed in a new demonstration plant in Philadelphia, PA in 1995. It contains the combustion components of a 1 MWe coal fired power plant, a 17,500 lb/hour steam boiler, coal storage an...

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...

The load following operation of coal-fired boiler-turbine unit in power plants can lead to changes in operating points, and it results in nonlinear variations of the plant variables and parameters. As there exist strong couplings between the main steam pressure control loop and the power output control loop in the boiler-turbine unit with large time-delay and uncertainties, automatic coordinate...

A black liquor recovery boiler has two main functions. On one hand, it generates steam from the heat energy liberated upon combustion of the organic constituents of black liquor burned in the boiler, whereby the recovery boiler serves as a steam boiler. On the other hand, the chemicals from pulp digesting sulphur and sodium are recovered from the black liquor, the recovery boiler then serving a...

The higher steam temperatures and pressures required to achieve an increase in the thermal efficiency of fossil fuel fired power generation plant necessitate the application of steels with improved creep rupture strength. The 9% chromium steels developed during the last three decades are of great interest for components of advanced, high efficiency power plant. In this Paper, the development of...

ABSTRACT The pressurized water reactor type power plant has a sophisticated automatic control systems. On the primary side, The Control rod system and the Soluble boron control the core neutron flux. On the secondary side, output steam is controlled by the turbine control valve and steam dump system. During the automatic control mode, the two sides work in a synchronized way so that transition ...

The paper is devoted to solution of some problems in nuclear power station generating unit intellectual control systems using genetic algorithms on the basis of control system model development, optimizations methods of their direct quality indices and improved integral quadratic estimates. Some mathematical vector models were obtained for control system multicriterion quality indices with due ...

The recent widespread diffusion of Combined Cycle Power Plants (CCPPs) is due to crucial technological advantages with respect to oil or coal fired plants. Among them, CCPPs guarantee higher efficiency and lower emissions. However, in the context of a deregulated energy market, better performances of the CCPPs control schemes are required during load transitions to allow for their use in grid f...

The present study investigates the impact of various factors affecting coal-fired power plant economics of 210 MW subcritical unit situated in north India for electricity generation. In this paper, the cost data of various units of thermal power plant in terms of power output capacity have been fitted using power law with the help of the data collected from a literature search. To have a realis...
