Spring 2010 Research

INTRODUCTION

The Fall 2009 Spring 2010 ANC team 's design of lime feeder had been carried on by the Sping 2010 ANC team continued the design from Fall 2009 team, based on the same idea , which that by using settling a slanting tube connected with on a vertical column, the lime could be fluidized apparatus would function as an inverted traffic cone which has a high velocity at the bottom and captured to fluidize big particles and a lower velocity at the top to capture small particles.(see 2009 design). However, in order to overcome the difficulties faced in the previous design, the new team improved the design by changing slanting tube's diameter changed from 1 inch to 2 inches, and setting up another vertical tube with a wye connection. (see new see new lime feeder design) 

In the following experiment experimental set-up with both new apparatus and old one, the team tried to determine design a series of experiments in order to determine all the possible parameters which may influence the lime feeder's performenceperformance, all those parameters were based on Spring 2010 team's hypothesis . (see hypothesis). In addition, from previous ANC team's proposal, it's very important to set comparison experiment to test each parameter separately, so the new team did all the experiment experiments with a single comparable parameter as the principle in experimental set-up. 2010 ANC team carried on its research by kept improving the lime feeder design and performence.

Based on the team's experimental set-up, (number) comparison experiments had been carried on, the results and analysis could be seen below. 
*Experiment 1*

*Experiment 2* 

*Experiment 3*

From the experimental observation and results analysis, the Spring 2010 team proposed several suggestions on how to possibly improve the design in the future, and studied the feasibility of implementing the design in Aguaclara plant. (see future challenges)
