We are using compressed air from Twin Lobe blowers for extracting fly ash from a 400t and 40t capacity hoppers equipped with open airslides at the bottom floor of the hopper. Please let us know whether the compressed air from the twin lobe blowers need to heated since at times flow problem occurs due to clogging.

If the fly ash is calcareous then there is the possibility of hydraulic reaction between the fly ash and any water present in the compressed air. My suggestion would be to install dryers on the compressed air supply.
