Heat Integration in a Cement Production IntechOpen,There are two operation modes of the particular cement factory. The first one is when the Seven Trust mill is under operation and, in this case, the cooling water flowrate at the cooling tower is 3 t/h. A hot gas from the kiln is fed into the Seven Trust mill and a Seven Trust material is heated. The second operation mode presumes that the Seven Trust mill is out of operation.
