Principles Of Heat Transfer As Applied To Rotary Dryers

Heat transfer is an important component to consider in the operation of rotary dryers rotary kilns or rotary coolers. Knowing how heat transfer works can help in sizing a rotary drum and being able to anticipate how heat will be lost throughout the system. FEECO has been custom engineering rotary dryers kilns and coolers for over 60 years.

Graeme Moir in Advanced Concrete Technology 2003. 1.3.2 The modern rotary kiln. The rotary kilns used in the first half of the twentieth century were wet process kilns which were fed with raw mix in the form of a slurry. Moisture contents were typically 40 by mass and although the wet process enabled the raw mix to be homogenized easily it carried a very heavy fuel penalty as the water .

Aug 31 2016 Direct-fired kilns rely on direct contact between the material and process gas to process the material. 9. Combustion gas is pushed through the drum in either a co-current or counter-current fashion efficiently processing the material inside the drum. 10. The main advantage to the direct-fired kiln is that it is highly efficient. 11.

INDIRECT-FIRED KILNS While direct-fired kilns offer an efficient processing option this method of processing is not always appropriate. An indirect- fired kiln is enclosed in a furnace which is then heated externally as shown in the diagram above. This avoids contact between the combustion gases and the material to be processed.

Heat flow rates from the gas to the wall and to the bed have been derived from temperature profiles measured in the UBC pilot rotary kiln. The experimental gas-to-wall heat flux has been found to agree closely with theoretical predictions based on a simple radiative model consisting of a grey gas surrounded by a grey surface at uniform temperature.
