Fluidized Bed. CHE 381 Group 5 3/30/2011 Alex Guerrero Andrew Duffy Bernard Hsu Daniyal Qamar Jeff Tyska Ryan Kosak Tomi Damo. Source: EPA. Introduction. Purpose Measure the pressure drop through a fluidized bed column Observe the affects of fluid velocity on the bed
CHE 381 Group 5
Relatively well separated particles
Constant Bed Temperature
Measurements are taken at Steady State conditions
Stack sieve trays accordingly to separate out sand
Determine sand and silica sample densities using graduated cylinder
Load respective column with sand ( 6-10 inches)
Turn on air supply and slowly open and increase air flow while taking recordings. Increments of 10 % of max flow
Record air flow rate, pressure drop, height of bed and any related observations
Repeat with second sand sample and repeat
Clean sand column
Load and heat up silica column
Repeat 3 -6 for silica column
Keeping the air flow steady using the valve at the bottom of column
Keeping the silica at a constant temperature
Filtering out size categorizes of sand particles
Sand could come out the top of the column and get into eyes
Keep hands clear of heat supply and heated materials
Use vacuum responsibly preventing unintended suction of personal items
Sand can get slippery when on the floor
