The action of anthracite and bituminous coal dusts mixed with quartz on the lungs of rats.

Belt and King (1945) studied the tissue reactions produced in animals by selected dusts from South Wales coal mines, and found that clean coal (low ash coal fraction containing 99% coal) produced only minimal fibrosis (grade 1) with simple foreign body reaction in 250 to 500 days. In experiments with high ash coal fractions which contained from 37 to 66% coal and about 1 to 3% quartz, the rest ...

Adsorption Capacity for Phosphorus Comparison among Activated Alumina, Silica Sand and Anthracite Coal

Experimental researches on adsorptive capacity of activated alumina, silica sand and anthracite coal for phosphorus were conducted. Results showed that performances of three filter media were all in line with Langmuir isotherm, and activated alumina adsorptive performance was much better than silica sand and anthracite coal for phosphorus removal. The adsorptive capacity of activated alumina, s...

Structural Dislocations in Anthracite

C nanomaterials promise to find many applications in areas that include electronics, photonics, energy, and sensing. Graphene occupies an important position in this emerging area. In view of our interest in the synthesis of soluble carbon nanotubes 7 and graphene, we have investigated routes to other soluble materials that have a high carbon content. Anthracite is of interest in this regard, as...

A Markov Model for Performance Evaluation of Coal Handling Unit of a Thermal Power Plant

The present paper discusses the development of a Markov model for performance evaluation of coal handling unit of a thermal power plant using probabilistic approach. Coal handling unit ensures proper supply of coal for sound functioning of thermal Power Plant. In present paper, the coal handling unit consists of two subsystems with two possible states i.e. working and failed. Failure and repair...

Noise Reduction in New Open-cut Coal Mines, Coal Handling and Preparation Plants

Noise emission from coal handling and preparation plants continues to be an important issue in Australia, with increasingly stringent legislation and environmental constraints being imposed on plant construction and operation. In recent times plant designers have endeavoured to obtain practical data to assist in the design of plants with reduced noise levels. A plant designed and built recently...
