rotary dryer burner sizing...
(OP)
Trying to calculate the burner size required to dry 7 MTPH of 18% humidity sand in a rotary dryer. The dryer has been sized for retention time = 1hr or 2.2m ID inside refractory x 15m LG on 1degree incline. Plan on 6" castable refractory lining. Anyone know how to determine the heat input required relatively accurately ?? Assume efficient seals :) MO

Do you know final humidity content in sand? Do you know maximun RH in air for this humidity content?.

They want the product humidity to be reduced from 18% to 0.5%. Not sure the RH - but client is in Costa Rica so i am gonna guess relatively high (~65%) ?
Thanks,

Fuel flow (Btu/hr)
Sand flow+sand water flow (he, Ce, Te)
Air flow , he funcion of (T & RH)
Your dryer outputs are.
Sand flow+sand water flow (he, Ce, Te)
Air flow , he funcion of (T & RH).
Air flow: You need RH and temp at dryer outlet to calculate this flow, with amount of water evaporated.

Do you feel 95% humidity leaving the dryer is a reasonable assumption at sea level ?
