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