how to increase sludge input into rotary dryer

Pyrolysis gasification of dried sewage sludge in a combined ...

A pyrolysis gasifier, with carbonization and activation steps, was developed to convert dried sludge into activated char and gas fuel energy. To determine the optimal driving conditions, parametric investigations were conducted on the amount of steam input, pyrolysis gasifier temperature and moisture content in the dried sludge.

Development of a high-efficiency rotary dryer for sewage ...

The drying efficiency increased with the increase of the internal temperature and the sludge residence time in the rotary drum, while the drying efficiency decreased when increasing the dryer load. In addition, it was shown that NH 3 and CO 2 were the primary components released from the sewage sludge drying process.
