The increasing cost of fuel oil forced the industry to search for alternate fuels, and biomass. In general, rice husks were considered an appropriate substitute producing energy. Because, use husk offered lot benefits such as reduction in emission sulfur other pollutants connected with fossil fuel, cheaper than coal (approx. 36%), carbon neutral. Hence, this paper, water, Fuel Steam generation ...

Main essence for the thermal power plants that may be either coal or natural gas power plants to be in command of the temperature and pressure controllers (PI.PD, PID) is generally employed. The raw material, coal is nosh in to the boiler using conveyer system and it is a time shifting one. This coordinated boiler turbine system, multivariable complex process, nonlinear and also slowly time var...

In this study, optical and thermal properties of normal grade and winter grade palm oil biodiesel were investigated. Surface Plasmon Resonance and Photopyroelectric technique were used to evaluate the samples. The dispersion curve and thermal diffusivity were obtained. Consequently, the variation of refractive index, as a function of wavelength in normal grade biodiesel is faster than winter gr...

OVERVIEW: Among the international efforts to curb global warming, practical application of CO2 removal technology and improvement of powergeneration efficiency — for reducing CO2 emission from thermal power plants (which will probably remain the prime source of power in future) — will, at the very least, become urgent issues over the next several decades. Accordingly, the Hitachi Group is aimin...

As a major utility system in industry, boilers consume a large portion of the total energy and costs. Significant reduction of boiler cost operation can be gained through improvements in efficiency. In accomplishing such a goal, an adequate dynamic model that comprehensively reflects boiler characteristics is required. This paper outlines the idea of developing a mathematical model of a water-t...

In this paper, the babbitting of a bearing in boiler feed pump of an electromotor has been studied. These bearings have an important role in reducing the shut down times in the pumps, compressors and turbines. The most conventional method in babbitting is casting as a melting method. The comparison between thermal spray and casting methods in babbitting shows that the thermal spraying babbitt l...

A critical review of air pollution emitted from thermal power plants has been carried out by considering several literatures. It is concluded that the disposal of fly ash generated in thermal power plants poses a problem, as it required a large amount of land for dumping, however if utilized properly, this may turn into a resource material for number of sectors for Indian economy. Also it is fo...

The life of quench oil is dependant upon its thermal stability. The thermal stability is a function of the quality of the base oil, the antioxidant package used, and the presence of heat and catalysts. In this paper, the mechanism of quench oil degradation and the function of antioxidants will be explained. An example of oxidation testing to determine the role of the base oil and antioxidants i...
