In this work, a tool to predict the performance of fossil fuel steam power plants under variable operating conditions or under maintenance operations has been developed. This tool is based on the Spencer-Cotton-Cannon method for large steam turbine generator units. The tool has been validated by comparing the predicted results at different loads with real operating data of a 565 MW steam power plant, located in Southern Spain. The results obtained from the model show a good agreement with most of the power plant parameters. The simulation tool has been then used to predict the performance of a steam power plant in different operating conditions such as variable terminal temperature difference or drain cooler approach of the feed-water heaters, or under maintenance conditions like a feed-water heater out of service.

Steam Power Plants

Most of the electricity being produced throughout the world today is from steam power plants. At the same time, many other competent means of gener-ating electricity have been developed viz. electricity from natural gas, MHD generators, biogas, solar cells, etc. But steam power plants will continue to be competent because of the use of water as the main working fluid which is abundantly available and is also reusable. The condenser remains among one of the key components of a steam power plant. The efficiency of a thermal power plant depends upon the efficiency of the condenser. In this paper, a the-oretical investigation about thermal analysis and design considerations of a steam condenser has been undertaken. A hybrid steam condenser using a higher surface area to diameter ratio of cooling a water tube has been analyzed. The use of a hybrid steam condenser enables higher efficiency of the steam power plant by lowering condenser steam pressure and increasing the vacuum inside the con-denser. The latent/sensible heat of steam is used to preheat the feed water supply to the boiler. A con-ceptual technological design aspect of a super vacu-um hybrid surface steam condenser has been theo-retically analyzed.

Electric Steam Power Plants (PLTU) need coal as fuel to produce electricity. The higher the electrical energy needed to eat, the more fuel will be used. This has happened in the construction of shelters 9 and 10 Suralaya Merak-Banten steam power plant (PLTU). This development is reaping various kinds of rejection because it causes environmental damage not only in the area around the development operation but also in the Greater Jakarta area. The rejection movement was initiated by local residents and supported by international Environmental NGOs.Pembangkit Listrik Tenaga Uap (PLTU) membutuhkan batu bara sebagai bahan bakar untuk menghasilkan energi listrik. Semakin tinggi energi listrik yang dibutuhkan makan akan semakin banyak bahan bakar yang digunakan. Hal ini terjadi pada pembangunan shelter 9 dan 10 PLTU Suralaya di pulau Jawa spesifiknya di daerah Merak-Banten. Pembangunan ini menuai berbagai macam penolakan karena mengakibatkan kerusakan lingkungan tidak hanya pada wilayah sekitar operasi pembangunan namun juga pada wilayah Jabodetabek. Gerakan penolakan diinisiasi tentunya oleh warga setempat dan didukung dengan NGO Internasional penggiat isu lingkungan.

Applied Thermodynamics is a graduate course at Kettering University. Undergraduate Thermodynamics serves as the only prerequisite. This course covers the concepts introduced in undergraduate thermodynamics and continues with the coverage of thermodynamic relations, mixtures and solutions, psychrometry, phase and chemical equilibrium, and chemical reactions. These concepts are then applied in detail to various power and refrigeration cycles. Topics such as mole fraction, mass fraction, enthalpy of formation, adiabatic flame temperature and the application of the Second Law to reacting mixtures are covered. Team projects are incorporated into this graduate course. Recent projects included a turbojet engine and a non-ideal regenerative steam power plant. The objective of the first project was to compute component efficiencies and the thrust force for a jet engine. The second project aimed to optimize the thermal efficiency of a non-ideal regenerative steam power plant by varying the feed-water heater pressure. Both projects utilized the Engineering Equation Solver (EES), a general equation solver with built-in functions for thermodynamic and transport properties. This article describes the projects and presents the solution techniques and the computed results. For the jet engine, computed results are based on actual test data obtained in Energy Systems Laboratory at Kettering University.

Sulfur dioxide and Nitrogen dioxide were significant emissions emitted from coal-steam power plants that may cause health problems for humans and damage the environment. Studying the SO2 and NO2 gradients in Indonesian residential communities is critical for evaluating resident's SO2 and NO2 exposure. The method developed to assist analysis of spatial SO2 and NO2 gradients on a community scale combines a mesoscale Lagrangian dispersion model with field observations around coal-steam power plants using GRAL. The objectives of this study focused on GRAL dispersion of SO2 and NO2 in an Indonesian residential community near the coal-steam power plant, with a 6 km x 8 km resolution. Analysis of this model indicates a correlation between simulation and observation, with SO2 coefficient correlation (R) within 0.5 – 0.82 and NO2 coefficient correlation (R) within 0.30 – 0.59. Model performances analyze by NMSE and FB. The SO2 model is comparable to observation data since it has a better average NMSE and FB than the NO2 model. Due to data limitation of observation collected by grab sampling instead of continuous ambient measurement system affect different respond time compared with hourly data from the model.

Rankine cycle is one example of vapor power cycles. One important application is in steam power plants. Properties of the important points in the cycle can be found from steam tables. However, reading values from a steam table is rather inconvenient particularly when there are many values to be read such in a simulation. Interpolation must often be done since the table only provides values of properties at determined points. Using equations of states for steam is very convenient since values can be computed quickly. Unfortunately, equations of states for steam are very complicated. A program written in MATLAB to assist the teaching of Rankine cycle using steam has been developed. MATLAB is used since it is widely available. Using this program, a lecturer can easily modify a problem and get the answer quickly. Students can also benefit from the program where they can solve problems and compare the results that they will get manually.

Steam Cycle

In design of a real steam power plant cycle with seven or eight open and closed feed water heaters, choosing the appropriate turbine extraction pressures has important effect on the cycle efficiency. By considering the steam cycle thermal efficiency as an objective function, various optimization techniques including the Full Search, Hook-Jeeves and Nelder-Mead schemes were applied for selecting the proper arrangement of feed water heaters and the optimum steam turbine extraction pressures. In order to optimally design and accurately analyze the behavior of steam power plant cycles, a modular software based on object oriented programming has been developed. Steam cycle elements used in this software while forming a set of independent objects, collectively present an inter-related behavior. In the design environment of the software, a complete steam cycle power plant can be visually designed and analyzed. The correct performance of this software in calculation of the state variations at various cycle points and the cycle thermal efficiency was checked and verified. The values of extraction pressures and mass flow rates at the optimum design point were assessed and found to be in agreement with the corresponding values of existing power plants. Based on the literature available, incorporation of all the design features involving modular aspect with optimization search using several algorithms and comparisons made of the results with actual power plant performances have not yet been successfully accomplished in a software package.

This study is concerned with the repowering of existing steam power plants (SPP) by gas turbine (GT) units. The energy integration between SPP and GT is analyzed taking into particular account the employment of simple and complex cycle gas turbines. With regard to this, three different gas turbine has been considered: simple Brayton cycle, regenerative cycle and reheat cycle. Each of these cycles has been considered for feed water repowering of three different existing steam power plants. Moreover, the energy integration between the above plants has been analyzed taking into account three different assumptions for the SPP off-design conditions. In particular it has been established to keep the nominal value for steam turbine power output or for steam flow-rate at the steam turbine inlet or, finally, for steam flow-rate in the condenser. The numerical analysis has been carried out by the employment of numerical models regarding SPP and GT, developed by the authors. These models have been here properly connected to evaluate the performance of the repowered plants. The results of the investigation have revealed the interest of considering the use of complex cycle gas turbines, especially reheat cycles, for the feed water repowering of steam power plants. It should be taken into account that these energy advantages are determined by a repowering solution, i.e. feed water repowering which, although it is attractive for its simplicity, do not generally allows, with Brayton cycle, a better exploitation of the energy system integration in comparison with other repowering solutions. Besides these energy considerations, an analysis on the effects induced by repowering in the working parameters of existing components is also explained.
