The reaction of hydration proceeded at the same time the vapor was introduced into the reactor that was filled with calcined dolomite. It has shown that the temperature has begun to fall from the bottom of reactor after increase of temperature by the heat of hydration reaction. The reaction initiated at the pipe wall and the heat was transfer to the center of block between the fins. The results show that the use of copper fin in the reactor reducted the hydration reaction time by half when compared to the case without using the fins.
