MODELING OF ENERGY FLOW BALANCES AT A FOUR LEVELLED PARALLEL FLOW PRECALCINER CEMENT PLANT

Öz

this present study, energy flow balances of parallel flow precalciner four levelled cement production systems were generated. At cement production systems, energy flow balances can be considered as either integrated or separately for preheater, calcinator, rotary kiln and cooler unit. Fundamental of this modelling is energy balance of plant units such as precalciner, calcinator, rotary kiln and grate coolers. Amount of energy of solid and gases at the input and output of rotary kiln, calcinator and parallel flow preheater siclones, can be calculated with this modeling.

DORT KADEMELi PARALEL AKI~LI ONKALSiNATORLU C;iMENTO FABRiKASINDA ENERJi AKIMLARI DENKLiKLERiNiN MODELLENMESi

Öz

Bu cahsmada, paralel akish onkalsinatorlu dort kademeli cimento iiretim sistemlerinde enerji akirm denklikleri kurulmustur. Cimento iiretim prosesinde enerji akmu denkligi bir biitiin olarak ele ahnabilecegi gibi bu cahsrnada oldugu gibi onrsrnci, kalsinator, doner firm ve sogutucu iinite icin ayn ayn denklik olusturulabilir. Bu modelin temeli, fabrika iiniteleri omsmci, onkalsinator, doner finn ve izgarah sogutucu enerji dengesine dayanmaktadir. Bu modelleme ile doner finn, onkalsinator ve paralel akish orusrticr siklonlann her birinin giris ve crkrslanndaki kau ve gaz kiitlelerin enerji miktarlan hesaplanmaktadir,
