摘要：Control of low-temperature drying facilities using unprocessed air causes multiple difficulties due to major variability of ventilationair properties, both daily and seasonal. This paper presents an analysis of operating parameters of a sludge solar dryingplant based on an approach that uses the concept of ventilation air drying potential. Formulas for the drying rate as a functionof temperature and humidity of the ventilation air are given. Analysis results are used to propose recommendations for controlstrategy for such facilities aimed at improving efficiency and lowering power consumption. The analytical work was based onexperimental data collected during operation of a test solar sludge drying facility located at a waste water treatment plant inSkar˙zysko-Kamienna (Central Poland).
