Abstract: Over the last decades, the production of energy from various sources (e.g. coal, crude oil, natural gas) has rapidly increased all over the world, partly caused by the relatively comfortable and prosperous life sought by people. It is true that energy utilization can bring tremendous benefit to humans. However, along with prosperity, environmental pollution cannot be neglected. To a great extent this pollution can be attributed to energy utilization, especially the combustion of fossil fuel. In general, pollution is the introduction of contaminants into the natural environment causing adverse changes. In the case of combustion, several toxic substance emissions such as sulfur dioxide (SO₂) and nitrogen oxides (NO_x) have been severely limited to very small values. To protect the environment from the adverse effects of emissions, many countries worldwide have adopted legislation to regulate various types of pollution as well as to alleviate their adverse effects. Both combustion modifications and after-treatment strategies have been employed to achieve the goal of emission control. During this process, various innovative methods have been invented and put into practice. Both methods have been extensively and rapidly commercialized worldwide, combined with combustion modifications, effectively mitigating the harm to the atmosphere.
