A three dimensional steady state mathematical model of a rotary calcining kiln for the petroleum coke is presented The model takes into account all the physical phenomena of interest from gas flow heat transfer volatile matter and coke dust evolution and combustion to the granular bed motion and the thermal effects of the refractories The model is built in
by the use of lime The choice of the lime kiln is of paramount importance to a lime producer It must be suitable for burning the selected feed stone and for producing the required quality of quicklime Several different types of kilns are used for the calcination process These kilns can be rotary kilns or shaft kilns
Petroleum coke calcining Coke calcining plants can be located in oil refineries captive plants in aluminum smelters or merchant plants Rotary Kiln The petroleum green coke is fed into a refractory lined rotary kiln where the volatiles are driven off during the calcining process in an oxygen deficient atmosphere
usually calcined in a gas fired rotary kiln or rotary hearth at high temperatures around 1200 to 1450 °C to remove moisture drive off volatile matters increase the density of the coke
Sarcheshmeh lime rotary kiln in the south of Iran consumes a lot of thermal energy compared with other rotary kilns As a result Sarcheshmeh lime kiln is being investigated for the potential to
— Momentum adjustment to maximize pet coke firing Pillard DNOxFLAM can be installed in any existing direct firing installation without replacing existing equipment s such as silos transport lines coal mills or mill fans APPLICATIONS — Cement rotary kilns — Lime rotary kilns — All other mineral process using rotary kilns Al Li Ni
ROTARY LIME KILNS G M Druzhinin A V Arseev and G F Mastykov UDC With operation on coke oven gas and a limestone load of 16 tons/h per kiln the thermal capacity of the kiln was 16"106 kcal/h at a total air consumption factor total= Fig i Design of burner for rotary kiln a existing design; b rec
A 2D axisymmetric computational fluid dynamics CFD model coupled to a 1D bed model has been developed to capture the key processes that occur within rotary lime kilns The model simulates the calcination reaction using a shrinking core model and predicts the start of calcination and the degree of calcination at the end of the kiln The model simulates heat
