Energy saving considerations for rotary calciners

摘要

Over the last two years, the cost of energy in the USA increased significantly. Previously, energy costs were relatively low and heat conservation was not seriously considered. Capital costs were the primary consideration, and efficient thermal design was efficient thermal design was secondary. Indirectly and directly heated high temperature rotary calciners and kilns are widely used in the chemical and mineral process industries. In many plants, they are the largest consumers of energy and correspondingly have become the focal point of energy saving considerations for producers in the USA and worldwide.
