초록

A system for drying wood particles and a method of operation wherein the wood particles are introduced into a dryer and contacted directly with a combustion system exhaust stream. VOC's emitted from the wood particles during drying are recycled to the combustion system for destruction. In one method according to the invention, a portion of the VOC-laden dryer exhaust stream is recycled to the dryer.

청구항

1. A method of drying a cellulosic material comprising the steps of: a. discharging an exhaust stream from a combustion device; b. directly contacting a first portion of the exhaust stream with a cellulosic material; c. transferring volatile organic compounds from the cellulosic material to the first exhaust stream portion; and d. introducing at least a portion of the first exhaust stream into the combustion device and destroying the volatile organic compounds therein.
