Methods for controlling flue gas temperature and voltage supply in electrostatic precipitators for cement manufacturing plants

摘要

The present inven relates to a method for controlling flue gas temperature in a cement manufacturing facility comprising a kiln (1), a flue gas optimizer (2), a mill (3) and an electrostatic precipitator (4) Gas is passed through the optimizer and from there through the mill or directly to the electrostatic precipitator whereby the measurement of the flue gas temperature in front of the electrostatic precipitator is carried out in the flow path of the gas so that if the temperature is too high, Water is supplied to the flue gas for cooling purposes in the unit. The present inven also relates to a cement manufacturing facility.
