Development of a tribological failure knowledge model
Many of the component failures occurring in service can be delayed by better incorporation of tribological principles into engineering design and maintenance. However, the concept of tribology has not yet penetrated successfully into the industry in general and there is an urgent need for the practical tribology design criteria and transference of tribological knowledge to the engineering ...

KNOWING THE PLANT’S STEAM QUALITY
Steam quality is the proportion of saturated steam (vapor) in a saturated condensate (liquid)/steam (vapor) mixture. A steam quality of 0 indicates 100% liquid (condensate), while a steam quality of 100 indicates 100% steam. One pound of steam with 95% steam and 5% of liquid entrainment has a steam quality of 0.95.The measurements needed to obtain a steam quality measurement are temperature, ...

Cogeneration steam power desalting plants using steam turbines
This paper presents the reasons and merits of using cogeneration generation power desalting plants (CPDP), the different methods used to rate their performance, and their drawbacks. The ratings of the CPDP are crucial, because the fuel cost allocation between the water and power depends on the rating method used. The ratings are usually based on the first and the second laws of thermodynamics. A ...

Case study - Fly ash for stone matrix asphalt in Oregon
Stone Matrix Asphalt (SMA) is the latest low wear, long life asphalt pavement. It has a proven track record in Europe and is growing in popularity with State Department of Transportations across the country. Georgia alone placed over two million tons of SMA on its roads last year. The Oregon DOT is the latest to adopt SMA and is using it as a high durability asphalt wearing surface on 10 miles of ...

Assessing and improving the efficiencies of a steam power plant using exergy analysis. Part 1: assessment
Energy and exergy analyses are used to examine the performance of a coal-fired steam power plant and to identify and evaluate possible modifications to improve the efficiency of the plant. The exergy analysis provides a detailed breakdown of the exergy losses (including waste exergy emissions and internal irreversibilities) for the overall plant and its components. The results show that ...

Assessing and improving the efficiencies of a steam power plant using exergy analysis. Part 2: improvements from modifying reheat pressure
The effect of increasing reheat pressure on the exergy efficiency of a coal-fired steam power plant is investigated. The results show that although the irreversibility rate associated with heat transfer in the steam generator decreases as reheat pressure increases, the overall-plant exergy efficiency decreases, mainly owing to the relatively large decrease in shaft power output. The results ...

Improving steam power plant efficiency through exergy analysis: effects of altering excess combustion air and stack-gas temperature
Modifications are examined to increase coal-fired steam power plant efficiency by reducing irreversibilities in the steam generator, including decreasing the fraction of excess combustion air, and/or the stack-gas temperature. Overall-plant energy and exergy efficiencies both increase by 1.4% when the fraction of excess combustion air decreases from 0.4 to 0.15, and by 3.5% when the stack-gas ...
