Abstract
A preheater or precalciner kiln is modified to feed solid fuel into a riser duct of the kiln to enable efficient environmentally sound use of solid waste-derived fuel. The modified kiln includes a solid fuel delivery port in the riser duct, a fuel feeder device for feeding solid fuel through the delivery port, and a fuel suspension device for holding the solid fuel for combustion in a fixed position in the kiln gas stream.
