Abstract: Rotary calcinator is common equipment used in catalyst production. Sudden stop accidentally happens in the production process. Improper handling may result in very serious consequences. Taking the electric heating rotary calcinator as an example, this paper introduced the structure, working principles and characteristics of rotary calcinators. Through stress analysis of the calcinator furnace cylinder at high temperature, it elaborated the possible consequences of furnace cylinder deformation and proposed the solution to the problem of furnace cylinder outage. By analyzing the causes for such failures, the paper put forth the preventive measures to avoid failures.

Key words: rotary calcinator, sudden stop, technical analysis, prevention
