Kilns: Design, Construction, & Operation.: Daniel Rhodes

The principles and methods involved in kiln design and construction receive a thorough and authoritative treatment. The information which applies to the structure and size of any kiln, be it gas-fired, oil-fired, wood burning, or electric, up draft or downdraft, is the basis for discussion of methods and procedures required by specific kilns.

Lumber Drying Theory Frank Controls

The subject of kiln drying lumber is probably one of the most hotly debated subjects in the forest industry today. It seems that there are as many theories about how lumber should be dried as there are people involved in kiln drying. This is an indication of the complex nature and the many factors that influence the removal of moisture from wood.

1. Kiln Capacity b. Chamber Dimensions Height Width

Lumber dry kilns come in a variety of sizes and shapes. One of the most important decisions to make early in the design process is to define the lengths of lumber that are expected to be put into the dry kiln. The kiln shown in Figure 3 was designed for a sawmill that only processed nominal 12 ft long sawlogs (actual length about 12-ft 6-in).

It is recommended that element calculations be worked out before furnace construction is started, as the size, number and length of the element support grooves (or tubes) required will be affected by the element design. Also, if a three-phase supply is to be used, it is helpful to have the number of elements divisible by three.
