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

Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.

Types and Classification of Different Furnaces Based on the method of generating heat, furnaces are broadly classified into two types namely combustion type (using fuels) and electric type. In case of combustion type furnace, depending upon the kind of combustion, it can be broadly classified as oil fired, coal fired or gas fired.

water or steam in the steam boiler receive heat by convection from the heating surface. When any fluid in a steam boiler is heated, its density is decreases and fluid become lighter. Then the heavier or cooler fluid will flow and replace the heated portion of the fluid. In turn the cooler portion become heated are example of convection.

Nonrenewable energy comes from sources that will run out or will not be replenished in our lifetimes—or even in many, many lifetimes.. Most nonrenewable energy sources are fossil fuels: coal, petroleum, and natural is the main element in fossil fuels. For this reason, the time period that fossil fuels formed (about 360300 million years ago) is called the Carboniferous Period.

An analysis was conducted on the relationship between the calorific value of different types of coal and the theoretical air requirement. It was found that the theoretical air volume required for generating the same amount of heat during combustion is the same for different types of coal. The concept of the air/coal ratio was improved by proposing the concept of the air/carbon ratio, which ...
