For example, drying beds could be used to produce a dry product in the warm, drier periods of the year and the mechanical equipment would be used when the weather is adverse to dewatering sludge on the drying beds.The drying beds would constitute the backup in the winter, and vice versa.
Gasification is made up for five discrete thermal processes: drying, pyrolysis, combustion, cracking, and reduction.All of these processes are naturally present in the flame you see burning off a match, though they mix in a manner that renders them invisible to eyes not yet initiated into the mysteries of gasification.
