· Coal is a fossil fuel that is, essentially, "the altered remains of prehistoric vegetation," as the World Coal Association (WCA) puts it. However, there are a number of different coal types. Coal originally began to form during the Carboniferous period, which took place between 360 and 290 million years ago. Put simply, plant matter accumulated in swamps and peat bogs, and
What is Coking Coal. Coking coal, also known as metallurgical coal, is used to create coke, one of the key irreplaceable inputs for the production of steel. There are many varieties of coal in the world, ranging from brown coal or lignite to anthracite. The property that really sets coking coals apart from other coals is its caking ability ...
Coal is used for heating the raw materials at 1450 degrees centigrade to turn into clinker. The grade of coal supplied in the cement manufacturing industry depends on the grade of limestone used in the cement manufacturing process. If the limestone used in the cement manufacturing process is of high grade then lowgrade coal is used and vice versa.
Brick plants sprang up all over the province, wherever the necessary raw materials were available (most importantly clay, of which the province has an abundant supply). In Manitoba, buffcoloured brick was the most common (and least expensive) with red brick used on more stately buildings. The construction of these kinds

· Today, all other brick manufacture is carried out in established permanent brickworks. Although the sizes of bricks altered across areas and through the centuries, by the earlynineteenth century bricks were manufactured to a statute which required that they should be twice as long as they were broad, normally being 8 by inches or 9 by inches.
· Metallurgical coal, also known as coking coal, is used to produce coke, the primary source of carbon used in is a naturally occurring sedimentary rock formed over millions of years as plants and other organic materials are buried and subjected to geological forces.
Wet bricks were stacked in one chamber and warm flue gases from a previous chamber, which was been fired, were drawn over them to dry them. The firing point was slowly moved around the series of chambers by adding fuel to the chambers usually from above. This allowed for the continuous burning of bricks.
