Consumption of fossil energy continues to increase and therefore reserves are decreasing, thus the switchover using into new renewable is necessary. Biomass especially from oil palm empty fruit bunches one potential resource as that can mixture with coal fuel for power plant. However, biomass has several weaknesses fuel; it containing high potassium content low heating value. Potassium will rea...

Coal, which is usually land plant in origin, occurs in many oil-producing basins. Microscopically, coal consists of various macerals (liptinite, vitrinite, and inertinite). The generative potential of coal reflects the hydrocarbon potential of the composing macerals (Kelly et al., 1985). Although most coals consist of predominantly vitrinite, some contain significant amounts (>20% of total mace...

Fired steam generators are the dominating technology of coal combustion in power plants. This paper presents a model for pulverized coal fired steam generators in Modelica. The model components are designed as an extension of SiemensPower, a Modelica library for transient simulation of power plants. The focus is on coal combustion, gas-particle-flow and radiation heat transfer in the furnace. T...

Studies were performed to compare the physical and chemical characteristics and the in vitro macrophage cytotoxicity of oil and coal fly ash. Sampling methodology was developed to collect size-fractionated particulate matter from the smokestack of either a coal-fired or an oil-fired power plant. Morphological studies demonstrated particle heterogeneity, although most coal fly ash particles appe...

Discharge of sludge from water works into waters will result in the increased deterioration of water environment. Therefore, an experimental study was conducted on the addition of conditioning agent to improve sludge dewatering performance. The result shows that coagulation is inadaptable to the treatment of sludge from water works and use of powdered coal ash from power plant as conditioning a...

Coal based power plant emitted pollution is responsible for environmental burden of disease (EBD) from solid fuel use (SFU) like combustion of coal or biomass. Environmental pollution due to operation of thermal power plants is also one of the factors for acute lower respiratory infection (ALRI), chronic obstructive pulmonary disease (COPD), lung cancer (from exposure to coal smoke), asthma, tu...

This research work presents data of the ambient air quality status of Ariyalur district of Tamilnadu, India. The air quality was assessed based on new national ambient air quality standard. The selected parameters were PM2.5, PM10, SO2, NO2. The average value of PM10 was found beyond the permissible limit at near power plant and near coal mill. The outcome of the study has been presented in the...

In this paper, we conduct a techno-economic analysis of a 1000 MWe solar tower aided coal-fired power generation system for the whole life cycle. Firstly, the power output (from coal and solar thermal energy) under variable direct normal irradiance and grid demand are studied. Secondly, a financial assessment is performed, including profits and losses of the plant project. Thirdly, sensitivity ...
