optimizing the use of steam in dry kilns


This means that if we generate steam at high pressure we can use smaller diameter piping to transmit the steam to the dry kilns. Using Steam When steam is used in a dry kiln, the generating process is reversed. If 100 psig steam is used in the dry kiln coil, 880 Btus of heat are removed from the steam to dry the lumber at a constant temperature of 338F.
