It should also be disposed of correctly. This is why an ash handling system is crucial in thermal power plants. Ash handling system ensures the process is environmentally friendly and normally runs without issues. However, maintenance of the system is vital. Any thermal power plant must choose an ash handling system depending on its requirements.
