Abstract

Aim of this diploma thesis was to get more specific and measured data of a modern precalcining system in a Turkish cement plant for further verification of the theoretical calculation for an Austrian engineering and project management company. Therefore a measurement method was created to measure pressure and temperature at several positions simultaneously. In addition to the existing measuring points at the preheater tower, new measuring points for hand-held measurement have been installed. The preheater tower is subdivided into sections, the so-called units, according to the cyclone stages, consisting of cyclones, riser ducts and meal pipes. All results of the existing measuring equipment and the additional measuring points were collected and elaborated. Relevant key values like pressure losses as well as temperature ratios of gas and raw materials in cyclones, riser ducts, meal pipes and other components of the precalcining system are stated. Surface temperatures were collected and subsequent calculations of heat losses through surfaces show possibilities for further technical advancements. Furthermore a heat balance for the preheater tower, including the calciner, was established. Calculations of the heat transfer within cyclones and riser ducts and of the heat content of raw meal in meal pipes are provided. In the top stage of the preheater tower (twin cyclones of the calciner string), one cyclone unit was analysed in more detail for a heat balance.
