The facility is located in Colorado Springs and consists of three BART-eligible dry-bottom, wallfired boilers (Units 5, 6, and 7). These boilers fire a variety of coal types, including coal from the southern Powder River Basin, ColoWyo coal (from northwestern Colorado), 20-Mile Foidel Creek coal (northwestern Colorado), and West Elk coal (western Colorado). Due to equipment limitations, these b...

Many thermal power plants use coal as their fuel. To handle the coal, each power station is equipped with a coal handling plant. The coal has to be sized, processed, and handled which should be done effectively and efficiently. While working in the coal handling plant the major factor which reduces staff efficiency is the working environment i.e. a dusty atmosphere. Lots of care is always taken...

The research results of coal characterization using the XPS method are summarized. Microsoft Visual Studio.net is utilized to build a database functional group characterization for coal, which contains over 1000 records including the kind of functional group, binding energy value, coal specie, producing area, sample preparation, and literature information. The database can be used to search and...

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...

This research was aimed at estimating possible Coal workers' pneumoconiosis (CWP) cases as of 2012, and predicting future CWP cases among redeployed coal workers from the Fuxin Mining Industry Group. This study provided the scientific basis for regulations on CWP screening and diagnosis and labor insurance policies for redeployed coal workers of resource-exhausted mines. The study cohort includ...

the present paper deals with the results of the foresight analysis concerning the development of energy technologies in upper silesia. twelve experts representing science, industry and independent authoritieswere involved in these investigations. upper silesia is a specific region in poland, characterized by coal energy technologies. as 9 result of steep and swot analyses several scenarios of e...

In most coal-fired power plants, pulverized coal and primary air flow from the pulverizers through a network of pipes to the burners. For proper operation of the boiler, all the coal pipes connected to any one of the pulverizers should carry the same coal flow rates and the same flow rates of primary air. Instrumentation is available commercially for making on-line measurements of coal flow rat...

Coal body is a type of fractured rock mass in which lots of cleat fractures developed. Its mechanical properties vary with the parametric variation of coal rock block, face cleat and butt cleat. Based on the linear elastic theory and displacement equivalent principle and simplifying the face cleat and butt cleat as multi-bank penetrating and intermittent cracks, the model was established to cal...

Large deposits of coal over vast expanse of lands attract mining companies, power stations and petrochemical companies and thus the development of coal towns with rail and road networks. High traffic volume of large quantities of coal across coal cities often result in the gradual accumulation of fine coal dust particles on road pavements, rail ballast and sleepers. The effect of coal dust on t...

The enrichment of coalbed methane (CBM) and the outburst of gas in a coal mine are closely related to the nanopore structure of coal. The evolutionary characteristics of 12 coal nanopore structures under different natural deformational mechanisms (brittle and ductile deformation) are studied using a scanning electron microscope (SEM) and low-temperature nitrogen adsorption. The results indicate...
