Performance enhancement of GT-ST power plant with inlet air cooling using lithium bromide/water vapour absorption refrigeration system
Performance improvement techniques in power generation systems especially in gas turbine-steam turbine (GT-ST) combined cycle (CC) power plants by compressor inlet air cooling prove to be much improvising. In this work, the performance enhancement of CC power plant by inlet air cooling method using lithium bromide-water (LiBr/H2O) absorption refrigeration system powered by waste heat from heat ...

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 ...

Difficult Complex Decisions For Coal-fired Power Plant Operators
Changing fuel prices, government regulations and technology all combine to make decision making difficult for operators and developers of coal-fired power generation facilities around the world. Power plant designers in developing countries face new local environmental regulations plus additional requirements stipulated by lenders such as the World Bank. In the developed world, the regulations ...

Coal-fired power on the way out?
The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

SAGA: a decision support system for air pollution management around a coal-fired power plant
Air quality models are currently feasible approaches to prevent air pollution episodes. From one of the first source-oriented modelling approaches for air pollution forecasting (Souto et al., 1994, 1996, 1998), a new decision support system for air quality management, SAGA, was developed to provide support to As Pontes Power Plant (APPP) staff. SAGA can provide air pollution forecasts and manage ...

Experimental investigation of the late phase of spent fuel pool accidents
Experimental programmes have been carried out in order to investigate the behaviour of nuclear fuel components in high-temperature air atmosphere, which characterises the main conditions of the late phase of spent fuel pool accidents. The tests provided new data on the oxidation of zirconium cladding in different atmospheres, on the oxidation and release of ruthenium from fuel pellets and on the ...

Adiabatic compressed air energy storage plants for efficient peak load power supply from wind energy: the European project AA-CAES
With the continuing expansion of electricity generation from fluctuating wind power the grid-compatible integration of renewable energy sources is becoming an increasingly important aspect. Adiabatic compressed air energy storage power plants have the potential to make a substantial contribution here. The present article describes activities and first results relating to this technology that are ...

New definition of fluid exergy in a gravitational field
This paper discusses the concept of working fluid exergy in an atmosphere stratified by a gravitational field, particularly the hot humid air in the atmosphere. A definition of exergy, different from that recently proposed by Petela (2008), is presented. Thermodynamic diagrams illustrate its elements and its technically feasible part in a transparent way. Reference papers are given for ...

Improve Boiler Efficiency
In many chemical plants, the electricity the plant uses is derived from a natural gas power plant or a co-generation plant burning waste gas streams. In large boilers (Figure 1), power plants bring together air and fuel (natural gas, waste gas, oil or coal) for combustion, which creates heat. The heat boils the water, creating steam. The steam runs through a turbine, which causes the turbine to ...

Biomass tools is common representative of bioenergy
As the text of the biomass energy sector, biomass pellets have actually played an crucial duty from the very start. The raw material going into the pressing chamber of the biomass equipment is squeezed out into biomass pellets by the rotation of the die wheel. Related post: biomass pellet machine price The result and efficiency of the biomass pellet maker are the basis for selecting a ...
