Hi Reald Tashi

Thankyou very much for the response.

I am modelling a precalciner for the cement production. As per the literature and previous simulations the the reactor Output should be between 830 - 870 °C . but in my case it is 800 °C.

Details:

The inlet streams contains gases solids. so i choose different stream class such as CISOLIDS for solids and MIXED for gases.

The required heat is supplied through combustion

Components involving in calcination process are

Gases : Ar, O2, CO2,H2O,N2

Solids : CaO, CaCO3,SiO2,Al2O3,Fe2O3,MgCO3,MgO

Main reactions :

CaCO3→ CaO + CO2 (1) (converstion 94%)

MgCO3→ MgO + CO2 (2)

Reactor :

Rgibbs

at 1atm pressure

I hope these details are enough or else please write me .

Thankyou,
