Coolers and Kiln Hoods
To cool the clinker, ambient air is blown via fans up through the porous floor of the cooler. The service environment of the cooler is extremely abrasive, subject to wide swings in temperature and alkali attack. Typically kiln feed used to make cement clinker enters the cooler at 1400°C and cools to about 150°C as it travels to the outlet.

Development of an Innovative Fluidized Bed Cement Kiln System 677 for cooling down the cement clinkers economically to the specified temperature of around 100°C. In the fluidized bed cement kiln system, the separate two kilns which have differ-ent functions as abovementioned, that is, SBK and FBK are applied instead of a con-
Vertical Shaft Kilns
Vertical Shaft Kilns. Lime shaft kilns are stationary vertical kilns where the raw limestone enters at the top and gravity flows through three thermally zoned sections known as the preheating, calcining, and cooling zones. The process heats the limestone from ambient temperature to 900°C, which is the point where the carbon dioxide is driven ...

Review of Fluidized Bed Technology Application for Adsorption Cooling
Adsorption technology utilizes low-temperature renewable and waste heat sources for cost-effective and environmentally friendly cooling and water desalination systems. However, the problem with existing adsorption refrigerators is the low COP. This is caused by poor heat and mass transfer in existing packed bed designs. The solution to …
Fluidized bed waste incinerators: Design, operational and environmental
In bubbling fluidized bed combustors (BFBC), an initially stationary bed of solid particles, located in the bottom part of the combustor, is brought into a fluidized state by primary air, supplied through a distributor: the bed particles are kept in suspension at fluidization velocities between 0.5 and 3.0 m/s. For BFBC applications, the size ...

Rotary Coolers
Rotary coolers work by tumbling material in a rotating drum in the presence of chilled or ambient air. The drum is set at a slight horizontal slope to allow gravity to assist in moving material through the drum. Lifting flights maximize heat transfer efficiency by lifting up material and dropping it through the chilled air as the drum rotates.
INTRODUCTION TO FLUIDIZED BEDS
Turbulent Fluidization. Turbulent regime has the following features:-. High solid hold-ups (typically 25-35 % by volume). Limited axial mixing of gas. Suitable for exothermic and fast reactions. Good gas-solid contact and hence, favors reactant conversion. high gas flow-rates operation and good for isothermal operation.
