Dusty environment Exposure to heat from the boiler Back burn Pellet overflow/underflow Danger of moving parts with high torque Belt slip or misalignment
Safety concerns:
Conveyor 1 (Feeds boiler) Research conveyor belt types and applications Research safety requirements Develop a general function layout using Visual Logics Rough frame design Optimal frame dimensions based on boiler/steam turbine intake Strength analysis (force and moment balance, bending stress, etc.) Motor selection Design drive based on boiler/steam turbine intake rate Determine necessary gear ratio (motor : drive – torque increase and speed reduction) Belt selection based on pellet load Placement of idlers on the frame (tension uptake) Selection of alignment and heat sensors Pellet regulation device- either before or after the conveyor Add finer details to Visual Logic
Conveyor 2 (from mill to storage) ***repeat steps used for Conveyor 1 with the additions: Elevation sensor for changing conveyor height with respect to storage pile height Actuator selection
Methodology
Research conveyor types Preliminary Visual Logic Layout Safety Requirements Rough Frame Design for conveyor 1
