Efficiency Performance

This study aims to determine the effect of changes in generator load on efficiency performance in steam power plants and to determine the amount of input power in the boiler. Data collection was carried out at PT. Bosowa Energi PLTU Jeneponto. The data are the power output, fuel consumption, and the calorific value of the fuel. Then perform data analysis by calculating input power and efficiency. From the result of the study, the highest efficiency is on May 20, 2018 at 18.00 with a load of 90.00 MW, namely 55.68% and the lowest efficiency is on May 12, 2018 at 03.00 with a load of 64.98 MW, namely 22.69%. The highest boiler input power based on the analysis results was on May 3, 2018 at 20.00, namely 356.61 MW, and the lowest boiler input power based on the analysis was on May 15, 2018 at 07.00, namely 128.14 MW.

Steam Plant

This paper describes the conversion of existing conventional steam power plants into combined cycle plants. A number of Dutch utility companies are currently performing or planning this conversion on their gas-fired power stations, mainly in order to conserve fuel. Modifications of boiler and steam cycle, necessary for the new concept, are presented in general terms, together with a detailed description of one of the projects.

Attractive Option

Most of investment in power generation industry tends to combined gas and steam turbine power plants due to thermodynamic and economic reason. Beside this tendency repowering of existing power plants is an attractive option for upgrading and life extension of existing power plants. In fact repowering is usage of combined cycle advantages for increasing power output and efficiency in steam power plants. Several approaches are proposed for repowering regards to condition of existing power plants such as life period and condition of parts of that and most important off all boiler condition. One of this approaches which provide opportunity of existing boiler reusing is converting existing power plant to fully fired combined cycle by installing a gas turbine and integration of that with existing steam units boiler. The aim of this paper is investigation of condition and how to integration of gas turbine and boiler. Also by exerting the condition and limitation in integration, the effect of gas turbine parameters to power output and efficiency of after repowering have been investigated. Finally the best condition of gas turbine parameters with high power and efficiency will be introduced.

Major Factors

The development of new power generation plants firing fossil fuel is aiming at achieving higher thermal efficiencies of the energy conversion process. The major factors affecting the efficiency of the conventional steam power plants are the temperature and, to a lesser extent, the pressure of the steam entering the turbine. The increased operating temperature and pressure require new materials that have major oxidation resistance. Due to this problem, in the last years numerous studies have been conducted in order to develop new coatings to enhance the resistance of steels with chromium contents between 9 and 12% wt against steam oxidation in order to allow operation of steam turbines at 650 0C. In this study, Si protective coatings were deposited by CVD-FBR on ferritic steel P-91. These type of coatings have shown to be protective at 650 0C under steam for at least 3000 hours of laboratory steam exposure under atmospheric pressure. Morphology and composition of coatings were characterized by different techniques, such as scanning electron microscopy (SEM), electron probe microanalysis, and X-ray diffraction (XRD). The results show a substantial increase of steam oxidation protection afforded by Si coating by CVD-FBR process.

Transient Thermal

Increasing the efficiency of steam power plants is important to reduce their CO2 emissions and can be achieved by increasing steam temperatures beyond 700 °C. Within the present study, the thermal behavior of a steam by-pass valve subject to cyclic operation with 700 °C steam is investigated experimentally and numerically. An innovative numerical approach was applied to predict the valve’s thermal behavior during cyclic operation, which is essential for fatigue life assessment of such a component. Validation of the applied numerical approach has shown good agreement with measurement results, indicating the potential of its application for the valve design process.

And Storage

A method for increasing the peak output of steam power plants through use of a low-pressure feedwater storage system is presented. The generalized availability analysis involves only the low-pressure turbine, low-pressure feedwater heaters, and the storage system. With daily cycling and storage charging at near base load conditions, the turnaround efficiency of the energy storage system was found to approach 100 percent. Storage system turnaround efficiency is decreased when the energy is stored during plant part-load operation.
