The first source of emissions is calcination, which decomposes quarried limestone (calcium carbonate) into quicklime (calcium oxide) and releases CO 2 as a by-product. The second source is the heat needed to achieve calcination, which requires temperatures over 2700°F (1500°C), or almost one-third the surface temperature of the sun.

1.. IntroductionThe uncertainty in predicting the behaviour of a particular limestone in a calcination process is due to the complexity of the calcination process which involves a five-step mechanism .Heat transfer resistances as well as pore diffusion resistance of the CO 2 evolved might have significant effects on the calcination rate. As it is reported by Doğu, changes in pore structure ...

Heat for calcination is provided through direct oxy-combustion of diesel in the RK calciner which requires flue gas recirculation for temperature control. A key benefit of this configuration is more uniform temperature distribution in the calciner and thus, increased usable length for calcination. 3.1.2 Test campaign using 1 kW th bench-scale unit
