# System and method for feeding bulk material into a pressurized environment

## Abstract

A system and method for feeding a high volume of low-bulk-density and pressure-sensitive feedstocks into a pressurized environment. The system includes a lock hopper filling system, one or more lock hoppers, a feed bin, and a feeder. The methods involve using such a system to feed bulk materials into a pressurized environment by feeding bulk material from a low pressure into the surge bin, filling the one or more lock hoppers from the surge bin, operating the lock hoppers, and discharging lock hoppers into feed bin, and discharging feed bin into the high-pressure zone using feeder.
