DESCRIPTION
Calcined petroleum coke (CPC) can also be used as a high-quality fuel for industrial kilns, furnaces, and boilers. When used as a fuel, CPC provides a high-energy, low-ash, and low-sulphur alternative to other fossil fuels such as coal or natural gas. The following are some of the properties that are important for high-quality fuel-grade CPC for kiln fueling:
- Fixed Carbon (FC): The FC content of fuel-grade CPC should be high to ensure a high-energy fuel.
- Sulphur Content (S): The S content should be as low as possible to minimize sulphur emissions during combustion, which can cause environmental issues and corrosion of equipment.
- Ash Content: The ash content should be low to minimize the formation of ash deposits and slag during combustion, which can cause fouling and erosion of equipment.
- Volatile Matter (VM): The VM content should be moderate to ensure easy ignition and stable combustion. Too high VM content can lead to flame instability and emission of unburned hydrocarbons.
- Particle Size Distribution: The particle size distribution should be optimized to ensure efficient combustion and to minimize dust emissions.
- Calorific Value: The calorific value should be high to ensure a high-energy fuel, and it should be comparable to or higher than other fossil fuels used for kiln fueling.
- Moisture Content: The moisture content should be as low as possible to ensure efficient combustion and to minimize the risk of corrosion of equipment due to water vapor.
