Coal is the primary fuel for electricity generation in India and its usage is continuously increasing to meet the energy demands of the country. This paper presents emissions of carbon dioxide (CO2), sulfur dioxide (SO2), and nitric oxide (NO) from thermal power plants in India for a period of nine years from 2001-02 to 2009-10. The emission estimates are based on a model in which the mass emis...

Simulators play a very important role in the operation of thermal power plants and also in the design of control systems for these plants. To cater to this requirement elaborate methodologies have been developed to simulate thermal power plant processes in an interactive way. Due to the intensive computations involved, such simulators use one or more high through-put computers known as the simu...

This paper presents a simplifiedlagrangian multiplier based algorithm to solve the fixed head hydrothermalscheduling problem. In fixed head hydrothermal scheduling problem, waterdischarge rate is modeled as quadratic function of hydropower generation andfuel cost is modeled as quadratic function of thermal power generation. Thepower output of each hydro unit varies with the rate of water discha...

In this paper we explore the tradeoffs between thermal storage capacity, cost, and other system parameters in order to examine possible evolutionary pathways for thermal concentrating solar power (CSP) technologies. A representation of CSP performance that is suitable for incorporation into economic modeling tools is developed. We also combined existing data in order to estimate the global sola...

This paper investigates the optimal configuration of micro combustion engines (kWel or kWth), the associated volume of thermal heat storage and the thermal capacity of an additional boiler (kWth) for heat supply in residential buildings with 30 units, which have been built in Vienna (Austria) during different construction periods (before 1919 to 2011). The target function for the configuration ...

The aim of this study is to analyze the reliability modeling indices and to study the mechanical system of a thermal power plant. The reliability of a system, equipment and a product is very important aspect of quality for its consistence performance over its expected life span. In fact, uninterrupted service and hazard free operation is an essential requirement of large complex systems like el...

Published data imply an average thermal efficiency of about 0.34 for U.S. electricity generating plants. With clever use of thermodynamics and technology, modern gas and steam turbines can be coupled, to effect dramatic efficiency increases. These combined-cycle power plants now reach thermal efficiencies in excess of 0.60. It is shown how the laws of thermodynamics make this possible. VC 2012 ...
