Process and device for feeding dispersible solid fuels into the calcinator of a cement clinker production line

摘要

In order to make sure, for cement clinker production lines with blown injection of dispersible solid fuels such as, for example, coal dust, into the calcinator which is provided with fuel, that an open flame does not occur at the fuel injection point, it is proposed according to the invention that the fuel is fed into a meal intake box that has a sloping raw meal chute and deflector slide and is arranged on the outside of the calcinator and connected to it through a wall opening and the fuel is pre-mixed with the pre-heated raw meal there, and then introduced via the deflector slide into the reaction section of the calcinator in order to form a gas-raw meal-solid fuel-suspension that is uniformly distributed.
