Evolution of heat

Simulates the process of heating the material (limestone)
How to specify the properties to him that in the range 900-1000 degrees. is the absorption of heat in an amount of 1660 kJ / kg?

P.S. my interest and how to set the CFX heat from the passage of solid state reactions in the material.

Cp is easy. Heat absorbed/given off due to chemical reactions is a bit trickier. Have a look in the tutorials for how to specify chemical reactions.

Cp is the specific heat as I understand?
It can be given to changing the length of the furnace.

And how to set that will be releasing heat to the material in the range of 1200-1250 degrees without using a chemical reaction.

I have no idea what you mean by this.

You cannot do it by adjusting Cp, unless the heat released/absorbed is small (which is usually not true). You may be able to do it with a source but probably the best way forwards is with a chemical reaction.
