DELETE EMPTY ROWS

Hi,
 How can I delete empty rows in a table that I have.
 f_huge_id | f_huge_name | f_huge_badge | f_huge_city
|    f_huge_edu
-----------+-------------+--------------+-------------+-------------------
         1 | Apparao     | A12345       | Anakapalli
| Brown University
         2 | Paparao     | A23456       | Madugula
| Town University
         3 |             |              |
|
         4 | Chinnarao   | A34456       | Uppalada
| Sink University
         5 | Gangaraju   | B34657       | Srikakulam
| Kulam University
         6 |             |              |
|
         7 | Appalaraju  | A34457       | Chodavaram
| AMAL college
         8 | Kanakarao   | A56788       | Pisinikada
| Temple University
         9 |             |              |
|
        10 |             |              |
|


In this table columns 3,6,9 and 10 are completely
empty. I tried

=>DELETE from my_table where fc_huge_name = ' NULL';
DELTE 0

However nothing is deleted.
Is there some command or statement that I am missing.
Can any one suggest some way.

Thank you.

Kumar.
