However, the use of these resources also has disadvantages including increase in unemployment because of more job losses and inability to match the impact of coal throughout the region. Reducing Coal Combustion Waste:

The reduction of coal combustion waste and enhancement of the efficiency of coal-fired power plants involves the use of various advanced coal combustion technologies. To reduce this waste in Philadelphia, the most efficient method is the use of Fluidised Bed Combustion, which is a very flexible means of producing electricity. This project would also be effective since its systems enhance the impact of coal-based electricity on the environment while reducing the emission of Sulphur Oxide and Nitric Oxide by approximately 90% ("Improving Efficiencies," n.d.).

The implementation of the process involves burning coal in a reactor consisting of a bed with which the gas is fed to ensure that the fuel remains in a turbulent state. Through this, Fluidised Bed Combustion enhances combustion, recovery of waste materials or products, and heat transfer. These kinds of systems permit the process to function at lower...

Moreover, Fluidized Bed Combustion systems use abandoned coal waste than previous systems because of their flexibility.
Conclusion:

As one of the common processes in Philadelphia, coal production is an important process in the city with numerous advantages and disadvantages. This process produces coal combustion waste that can be reduced through Fluidised Bed Combustion to improve efficiency.
