What does 'blanketing' refer to in combustion processes?

Blanketing in combustion processes refers to controlling combustion air to reduce emissions. This practice is important because managing the air-fuel ratio can significantly impact the efficiency of the combustion process and the amount of pollutants produced. By adjusting the amount of air that mixes with the fuel, it is possible to optimize combustion conditions, leading to more complete burning of fuel and fewer harmful emissions, such as carbon monoxide and unburned hydrocarbons.

This process often involves ensuring that there is sufficient oxygen to support combustion while avoiding an excess that can lead to increased formation of nitrogen oxides, which are another major pollutant. Effective blanketing strategies help maintain the balance necessary for clean and efficient combustion, which is a critical concern in power engineering and environmental control.

Understanding how to manage combustion air is vital for operators aiming to comply with regulatory standards and improve overall systems performance.
