China is the biggest coal product and consumption country around the world. Lots of coal consumption resulted huge carbon dioxide (CO2) emission, especially for coal-fired power plant in China. Oxy-fuel combustion is currently considered to be one of the major technologies for CO2 capture in power plants. The ash formation mechanism and mineral transformation in high CO2 atmosphere is different...

Mercury and radionuclides (natural U and its decay series products and artificial 137Cs) were measured in sediments of the Ka{tela Bay (eastern Adriatic coast) in the vicinity of a former chloralkali plant. The depth distributions of radionuclides and mercury revealed that sediments in front of the factory represent a mixture of natural sediment and coal ash originating from the coal used in th...

Currently coal fired power plant requires bunker or stock piles in order to place the coal for storage purpose and to use it effectively when demand arises. Real time sensors are used to sense level of the coal and to pass data to computational systems for processing hence further actions such as refilling and distributing of coal can be automated. Further the control action in level sensing ca...

Homogenization is the processing of one type of material so that the inherent fluctuations in respect of quality and/or size distribution are evened out. In blending coal, the aim is to achieve a final product with a well defined composition, from two or more coal types, so that the elements are very well distributed and no large pockets of one type can be identified. In mixing, traces of the i...

Online coal analyzers have been in commercial use for more than two decades now, with coal producers accounting for most of the units purchased. In the past three years or so, coal-fired power plants have shown an increasing share of the analyzers bought. This article explains the most common applications of analyzers at power plants, ranging from boiler optimization to compliance with emission...

Lignite from Mae Moh mine is the largest source of solid fuel for electricity generation in Thailand. It is used in pulverized coal-fired boilers of a 2400 MW thermal power plant. Its high CaO content in ash is a major concern that can affect severe slagging. In this paper, potential of slag occurrence in the power plant was investigated by numerical simulation. The FactSage thermochemical pack...

In recent years, subbituminous coal from the Powder River Basin and lignites from Texas and North Dakota have captured an increasing share of the power generation market involving pulverized coal-fired power plants. However, these coals contain relatively large amounts of moisture, which affect unit performance, stack emissions and plant maintenance costs. The moisture also results in fuel hand...

Polycyclic aromatic hydrocarbons (PAH) are major toxic air pollutants released during incomplete combustion of coal. PAH emissions are especially problematic in China because of their reliance on coal-powered energy. The prenatal period is a window of susceptibility to neurotoxicants. To determine the health benefits of reducing air pollution related to coal-burning, we compared molecular bioma...

background and objectives: active coal is applied in tissue culture media as the absorbant of phenolic compounds and toxic materials; but no research has been done regarding its direct application like spray on plants. application of this material as the carbone source is based on researches done by sucrose; which had highly positive effect on plant growth and development. thus; a hypothesis wa...

Sulfur emission from coal combustion presents many environmental problems. The techniques used to reduce the amount of sulfur in coal before combustion, include physical, chemical and biological processes.Biological processes based on degradation of sulfur compounds by microorganisms offer many advantages over the conventional physical and chemical processes. The processes are performed und...
