Lime production is one of the most energy intensive processes in the chemical industry. In order to reduce the energy costs alternative fuels can be used to replace expensive fossil fuels such as (powder) coal or natural gas. On top of that co-combustion of alternative fuels can reduce CO2 emission, contributing to a better environment.
In cement kilns co-combustion is commonly used to reduce fuel costs. Co-combustion is also environmentally benign, specifically as no rest products remain after combustion. The combustible materials are used to generate heat while the remaining ashes are completely absorbed in the clinker.
New environmental legislation and fierce competition has shifted the attention of power/electricity producers to alternative fuels. Co-combustion of alternative fuels can be used to replace expensive fossil fuels, such as coal and reduce CO2 emission, contributing to a better environment.
