Coal has become an important energy source for human society due to its availability, low cost and important economic value. However, when burning coal, the environment of the nearby regions will be polluted due to the emission of the various heat-trapping toxins that coal contains. Therefore, it is extremely important to exercise proper selection when choosing coal for usage.
The selection of coal should depend on various factors such as its ash content and sulphur content. The ash content refers to the amount of residue left over after coal has been burned. The higher the ash content, the more impurities the coal contains. Therefore, it is essential that the ash content of the coal is kept as low as possible. Similarly, the sulphur content of the coal will give a good indication of how polluting the coal is. It is best to choose coal that has a low-sulphur content in order to prevent air pollution.
The moisture content of the coal should also be considered in the selection process. Coal that is too moist will not burn efficiently, resulting in excess smoke and pollution in the atmosphere. Therefore, it is best to choose coal that has a low-moisture content in order to prevent air pollution.
The size of the coal is another important factor to consider when selecting the right coal. Smaller coal particles burn more quickly, resulting in faster combustion and increased air pollution. Therefore, it is important to pay attention to the size of the coal particles when choosing the right coal.
In conclusion, coal is an important energy source for human society, but it is important to exercise proper selection when choosing coal for usage. Factors such as ash content, sulphur content, moisture content and the size of coal particles, must all be considered in order to ensure a clean and efficient burn. By exercising proper selection when choosing coal, we can help to reduce emissions and create a better environment for our planet.
