1. Pre-Combustion Technologies
These technologies focus on preparing the coal before it's even burned. One of the most important is coal gasification. Here, coal is converted into a synthesis gas (syngas) composed of hydrogen, carbon monoxide, and other gases. This syngas can then be used to generate electricity in a more efficient and cleaner way. Gasification captures pollutants before combustion, which is a major advantage. Another pre-combustion method is coal washing, where impurities are removed from the coal. This reduces the amount of pollution released when the coal is burned. This process reduces the amount of sulfur, ash, and other undesirable materials in the coal. Overall, pre-combustion technologies allow for greater control over the emissions produced. This helps to create a cleaner-burning fuel. The focus on pre-combustion technologies is to maximize the efficiency of the process.
2. Combustion Technologies
Combustion technologies focus on cleaning up the emissions during the burning process. One key technology is fluidized bed combustion. In this process, coal is burned in a bed of hot, inert material, such as sand or limestone. This method allows for lower combustion temperatures, reducing the formation of NOx. The limestone captures sulfur dioxide (SO2), preventing it from being released into the atmosphere. Another combustion technology is the use of advanced burners. These burners are designed to improve the combustion process, reducing the amount of pollutants formed. By optimizing the conditions in which coal burns, the amount of harmful emissions can be significantly reduced. These combustion technologies are important because they directly address the pollution that occurs during the burning of coal. They provide an immediate solution for cleaning up coal emissions.
3. Post-Combustion Technologies
These technologies tackle the emissions after the coal has been burned. The most well-known is carbon capture and storage (CCS). CCS captures CO2 from the flue gas. It then compresses it and stores it underground, preventing it from entering the atmosphere. This is crucial for addressing climate change. Another post-combustion technology is flue gas desulfurization (FGD), which removes SO2 from the flue gas. FGD, or scrubbers, use a variety of methods to trap SO2 before it is released from the smokestack. Selective catalytic reduction (SCR) is another important technology. SCR systems use a catalyst to reduce NOx emissions. The focus is on capturing pollutants after the combustion process. This ensures that the emissions released into the atmosphere are as clean as possible. Post-combustion technologies are designed to reduce the impact of coal-fired power plants.
