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).

May 27, 2020· Paragon kilns: PMT10 = 0,676 W/cm² KM24D = 1,08 W/cm² I do not know the insulation value of these commercial kilns but I think if one uses soft ceramic firebricks the insulation value should be on par. To ease calculation and also to be on the safe side I think calculating with a value of 1 Watt per cm² of chamber surface is feasible. Example:

Calculating Kiln Volume By Marc Ward. From the November/December 1996 issue of Clay Times. To determine the amount of heat (BTUs) required for your kiln to reach a desired temperature in a certain time frame, you need to know your kiln's volume. To calculate the volume, measure and record its height, width and depth.
