Question

List combustion factors affecting VOC emissions. Explain your answers.

Answer 1

Answer and Explanation:

VOC stands for Volatile Organic Compounds are the emissions in the form of gases from some specific liquids or solids. These includes a various chemicals, some of which includes adverse effects on health in short-term  and long-term. These emissions originate from furnaces and  boilers  in industries.

Factors that affect the VOC emissions are

• Combustion  Efficiency
• Time of residence: high residence time at high temperature of combustion gives low VOC emissions as outcome.
• Temperature of Combustion : Low emissions of VOC results from High temperature of combustion.
• Mixing of combustion air and fuel in motion with turbulence or turbulent motion: Since partial or incomplete fuel combustion results in high VOC emissions.
• VOC species like Benzene, etc present in the fuel(combustion fuel).
