There are various methods of power generation such as combined cycle power plants. There are many variables in a power plant boiler unit, but the most important variables are Pressure and specially drum level that control system should be put it in the safe range. The purpose of this article is, modifying the oscillatory behavior of the drum level of Kerman combined cycle power plant and especi...
In this paper, a new power, heating and hydrogen cogeneration cycle from Sabalan geothermal two wells is proposed and analyzed. In the proposed system, a new double flash cycle and organic Rankine cycle are used for power production. A proton exchange membrane (PEM) is also used for hydrogen production and the domestic water heater is used for heating. The impacts of some design parameters, suc...
combined cycle performance can be improved by improving the performance of gas turbine based topping cycle. amongst various options the effective cooling of gas turbine blade for realizing the higher turbine inlet temperatures is one of the attractive options. the present paper deals with the thermodynam-ic analysis of advanced technology gas/steam combined cycle based power plant having closed...
introduction: the major target of this paper shows effect of selected decision variables in the steam system foroptimization of thermal combined cycle power plant.material and method: exergoeconomic, and other similar terms used to imply the combined thermodynamicand economic analysis of energy systems, which helps to increase the efficiency of a plant without jeopardizingits economic viability...
BACKGROUND AND PURPOSE Disability-adjusted life year (DALY) metric reflects years of healthy life lost because of living with disability and years of life lost because of premature mortality. Widely used in epidemiological analyses, DALY has not been applied to acute stroke trials. METHODS From previous studies, we derived, for each modified Rankin Scale level, disability weights, disability-...
BACKGROUND AND PURPOSE The simplified modified Rankin Scale questionnaire (smRSq) enables a reliable and rapid determination of the modified Rankin Scale score after stroke. We test the reliability and validity of a slightly revised smRSq. METHODS Fifty consecutive outpatients 4.83 ± 3.00 months after stroke were scored with a slightly revised smRSq by 3 raters selected consecutively from a l...
