Method and apparatus for the introduction of solid dusting fuel in the calciner of a cement clinker production line

摘要

System for feeding coal dust fuel into a calciner, of a cement clinker production line, mixes the incoming fuel with preheated fuel dust in the inlet box to be pushed into the calciner without forming an open flame. ??System to feed solid and dusty fuel (17) into the calciner (10) of a cement clinker production line, e.g. coal dust, has an inlet box (13) outside the calciner, and linked to it through a wall opening (10a). The feed path is through an angled slide (14) and a beating push unit (15), for the coal dust to be mixed with preheated fuel dust (12). The heated dust is moved into the reaction stretch of the calciner by the push unit to form a suspension of gas and raw dust and solid fuel in a homogenous distribution.
