Waste gases produced in a rotary kiln making cement

Apr 16, 2021

heat in the combustion gases is recovered in a boiler to give steam, which can be used in the process or in other waste treatment processes, or used to generate electricity to be delivered to the electric grid. The ashes (bottom ashes, fly ashes and flue gas cleaning residues) produced in the rotary kiln are disposed in a dedicated landfill
