A set of equations has been derived to calculate the solids holdup on angular and extended-circular flights in such dryers. three examples of the practical use of these equations are presented. these include estimation of the design holdup of the dryer, selection of the number of flights, and exploration of the flight cascade.
In direct heat rotary dryers, a hot gas flowing through the dryer provides the heat required for the vaporization of the water. to promote gassolid contact, most direct heat dryers have flights, placed parallel along the length of the shell, which lift solids and make them rain across the section of the.
It is important to know the characteristics of the infeed product to choose the best flighting design. a rotary drum dryers greatest asset is its ability to accommodate a product that has multiple size particles and moisture contents by utilizing the right flighting package. as seen in the picture above the wood is in a variety of shapes and.
Indirect flue gas tube dryer. another type of indirect rotary dryer is the flue gas tube type. hot gases generated inside the combustion chamber are conveyed inside concentric rows of tubes installed circumferentially to the cylinder. along the length of the tubes, intermediate supports are.
thermal inefciencies in the dryer exhaust heat content in convective dryers, sensible heating of solids, heat losses from dryer body. 2 thermal inefciencies in the utility heat supply system steam generation efciency, steam leaks and mains losses. 3 additional energy demands power for solids transport, vacuum pumps and air.
