TH215A - The process of heating large quantities and objects in a rotary kiln - Google Patents

Abstract

To heat large volumes and volumes of material in a rotary kiln with hot gas below the melting point. Of objects contained in the furnace Must be prevented Causing unwanted scaly crusts, which will occur during the Use the furnace as usual. Or when operating a rotary kiln in Low turnover during short-term crashes For this purpose, the heat is emitted in a controlled manner within the range of the rotary kiln. That is, the stove wall and the inner wall. Get cooling To increase the inner surface area of the rotary kiln Only the submerged part in the furnace has a lower temperature. Objects in the furnace And exposed to the aforementioned surface areas up to 50 degrees Celsius
