The historic Coplay Cement kilns in Lehigh County, Pennsylvania Credit: Nicholas A. Tonelli. Due to the nature of cement production, cement kilns require temperatures of 2000°C in their main burner. Excellent conditions for waste derived fuels, they have become a standard fuel for many cement kilns around the world.
This project explored the feasibility of using chipped asphalt shingle materials in cement manufacturing kilns and circulating fluidized bed (CFB) boilers. A method of enhancing the value of chipped shingle materials for use as fuel by removing certain fractions for use as substitute raw materials for the manufacture of new shingles was also explored.
Waste Heat Recovery Power Generation Systems for Cement Production Process. Cement production process is highly energy intensive with approximately 3-4-GJ energy consumption per ton of cement produced. Moreover, energy costs are responsible for 25% of total production costs, whereas 75% of primary energy usage is thermal energy.
C. Energy Calculations Cement production is an energy intensive process, consuming about 4 GJ per ton of cement production. Theoretically, producing one ton of clinker requires a minimum of 1.6 GJ heat . Total quantity of waste hot gasses available at kiln inlet and kiln outlet after waste heat recovery
A lime kiln is a kiln used to produce quicklime through the calcination of limestone. In the process of cement and quicklime manufacture, kilns are permitted by the Environment Agency (EA) to burn substitute fuels in place of the traditional fuels, such as coal.
