Co-combustion in cement kilns
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.
High quality fuels
Subcoal® products, ranging from fluff to pellets, are well suited for co-combustion in cement kilns. The high quality of the fuel and the corresponding specifications fulfil the requirements set forth by the cement industry with respect to for instance chlorine- and ash content.
Powder concept
The unique Subcoal® powder concept allows the Subcoal®pellets to be grinded into a fine consistent powder of <2 mm. This fine powder is characterized by a short burn-out time and could be used to further increase the co-combustion rates at the cement kilns. An increased co-combustion rate further reduces energy costs and increases profitability for cement kilns.
