The present invention pertains to a wood drying kilns system which eliminates the discharge of kiln water and enhances the quality of the wood product
. In particular, the kiln water is gathered into a collection basin. An evaporator is fluidly coupled to the collection basin to convert the collected water to steam which is introduced into the kiln and harmlessly vented to the atmosphere. In this way, the effluent is safely eliminated without any discharge of the water as a liquid. Further, the use of steam in the kiln balances the drying of the wood so as to avoid splitting, warping, etc. of the lumber products.
