1.0 INTRODUCTION

This section provides background information on sludge feed systems, blowers and
fans, and burners and supplemental fuel systems.

2.0 FEED SYSTEMS
There are three common types of feed systems: cake pumps, belt conveyors, and
screw conveyors. Fluid bed incinerators are typically fed in or just above the sand
bed, although some systems have feed ports in the freeboard. The fluid bed feed
