Improving of Maintenance of Humidifying System in Conventional Wood Kiln Dryers

During wood drying, the formation of limescale deposits on conventional drying kiln components frequently causes difficulties, especially on nozzles for dispersion of water mist, as a result of the use of “hard water” and technologically unprepared water. Frequently inadequate cleaners for the remov...
