Kiln cement plant pdf

Apr 24, 2020

A cement kiln producing clinker (the main constituent of cement), is by its nature an efficient tool for the recovery of minerals and energy from waste. Below are some reasons why. Kilns allow for complete burn-out of waste-derived fuel due to: The high level of oxygen at the kiln burner allows for rapid combustion

    To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to +1300 C and must be cooled down to a temperature of about +200 C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air. Pressure

    A development of this process is the 'precalciner' kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85%-95% of the meal is decarbonated before it enters the kiln
