INFLUENCE OF COAL ON COKE PROPERTIES AND BLAST-FURNACE OPERATION855 to be the same for coal of the same rank in all the stages, regardless of its source. Tables 1–4 compare the characteristics of the coke and blast-furnace operation with different batch com-positions. The characteristics in Table 1 indicate that
The effect of various coal properties like ash content, moisture content, fixed carbon and calorific value on specific coal consumption in a typical thermal power station in India is analyzed. It is observed that the specific coal consumption is a strong function of moisture content, ash content and fixed carbon.

The uptake of mercury (II) from aqueous solution by a range of coals has been studied and the results have been compared to those for a number of other sorbents, including commercial active carbons and cation-exchange resins.
Ash Content and Coal Composition Compared to other factors, such as price, heating value, sulfur content, and availability, coal ash content is the most important factor in selecting coal because coal ash content has the most impact on the performance of a slagging gasifier .

INFLUENCE OF COAL PROPERTIES ON THE CO-COMBUSTION 333 3.1. TG and DTG analysis of sludge and inferior coal under different mixing ratios First of all, the inferior coal of 120-150 mesh size were used in the experiments.
This report examines the influence of coal properties on the emission of pollutants to the atmosphere. To illustrate this, four pollutants are considered. They are: sulphur oxides, nitrogen oxides, particulates, and trace elements. These pollutants are representative of the various impacts of the coal properties.

Blending of coal and petroleum coke was also reported to investigate the influence of vanadium adding to flow property . Many of these studies on coal blending above have concentrated on the fusion properties and reactivities of blended coals.
Highlights Coal maceral liquefaction was analyzed by Quantum Chemistry. Effect of chemical structure and physical properties was investigated. Chemical structure change was calculated by the quantum chemistry. The average pore size and the liquefaction yield were positively correlated. The chemical bond cleavage activity had an influence on liquefaction yield.
The effect of coal properties on the rheological properties of coal oil mixtures (COM) has been studied. Coal samples having different ash and moisture contents have been used to study the effect of these components on rheological properties of coal oil mixtures.
The coal char structure is influenced not only by the properties of the parent coal, but also by the operating condition such as the heating rate [3,4], pressure, the maximum temperature experienced the residence time at this temperature and the gaseous atmosphere of the conversion process .
But in recent years there has been a rapid increase in domestic coal sales because the Indonesian government is committed to its ambitious energy program (implying the construction of various power plants, mostly coal-fired because Indonesia has plenty of coal reserves).
Grey System Theory is applied to study the influence of the coal properties on the emissions of nitric oxides from fluidized bed coal combustion.
