In order to overcome the problem and make the bitumen workable at ambient temperatures bituminous emulsions can provide a suitable solution. A bituminous emulsion is a dispersion of bitumen in water plus emulsifying agents. Hot bitumen will break into very small droplets, typically 1–20 m in size, by using a colloid mill.

· Bituminous coal contains the mineral pyrite, which serves as a host for impurities such as arsenic and mercury. Burning the coal releases trace mineral impurities into the air as pollution. During combustion, approximately 95 percent of bituminous coal''s sulfur content gets oxidized and released as gaseous sulfur oxides.

To summarize the coal mill controls, they may be divided basically into two major categories:. 1. To control the quality of coal being sent to the burners located on the furnace walls. The word quality here means the temperature and fineness of the PF. The set temperature values are dependent on the percentage of volatile matter that exists in the main fuel.

Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or is of higher quality than lignite coal but of poorer quality than is usually the result of high pressure being exerted on lignite. Its coloration can be black or sometimes dark brown; often there are welldefined bands of bright and dull material within the

Coal is a hard rock which can be burned as a solid fossil is mostly carbon but also contains hydrogen, sulphur, oxygen and is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.. Peat, and therefore coal, is formed from the remains of plants which lived millions of years ago in tropical wetlands, such as those of the late Carboniferous

A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output.

Bituminous coal is dark brown to black in colour and commonly banded, or layered. Microscopically, three main groups of macerals (individual organic constituents of coal) can be recognized: vitrinite, liptinite, and glassy material in most bituminous coal is vitrinite, composed of macerals derived primarily from woody plant tissue.
