From around 1910 various direct firing mills were tried and direct firing became progressively more popular until by 1970 nearly all new installations were direct fired. However the development of precalciner kilns reversed this trend because in these fuel is fed to the system at two or more points and this is most conveniently achieved with a
Co-firing is the combustion of two (or more) different types of materials at the same time. One of the advantages of co-firing is that an existing plant can be used to burn a new fuel which may be cheaper or more environmentally friendly. For example biomass is sometimes co-fired in existing coal plants instead of new biomass plants. Another
