    Mass And Energy Balances Over The Lime Kiln In A Kraft

    The purpose of this thesis is to create a model of the lime kiln that performs mass and energy balances over the process. This model is to be integrated in the WinGEMS software that is used to simulate mill systems in the pulping industry. There is an existing lime kiln block in WinGEMS but since has proven inadequate and in need of replacement.

    The burning zone is the last stage before the material exits the kiln. A single burner fires toward the approaching material, and precise temperature measurement is important to control the firing of the burner. A PSC 2color pyrometer is effective for monitoring the burner zone as they compensate for dust that can obscure the sight path.
