Blow Away Your Soot!Written by Thomas Yoon
Continued from page 1
that steam going through soot blower is dry. 3. Once steam is considered dry, drain valve is shut off, and soot blower is turned. Most soot blowers are constructed in such a way that when it is rotated, a steam port is uncovered and steam can enter into it. 4. The steam shoots out from soot blower tube that is inside boiler fireside. Many small holes for steam to emerge are drilled along length of tube. As tube rotates, position of steam jet will also move with it. After a full rotation, all areas around soot blower tube should be clear of soot. (However, it depends on how thick soot is, speed at which soot blower is rotated, and how efficient soot blowing is) 5. After completing soot blowing, steam supply is shut off again.The operation of soot blower can be done manually or by remotely controlled motor drive. A motor driven soot blower will usually include some means of turning manually in case motor fails. The soot that is blown away from heat transfer surfaces of boiler will be carried together with hot gases out through chimneystack. If there is a dust collector, soot will be caught by it, otherwise it goes out to environment as particles of carbon and ash. Folks, hold your breath! Don't hate that Housework!

Continued from page 1
The characteristic shape of these cooling towers is usually rectangular shape. Depending on design, there may be several small fans installed at top of cooling tower. However, fan(s) may also be located at sides of cooling tower and air may be ducted. The counter-flow type of cooling tower makes use of air flowing in opposite direction and against flow of water. In one design, water flows out through rotating spreader arms to distribute water and let it drop through plastic diffusers evenly. In this design, shape of cooling tower is a bottle shape. It is fitted with one single large fan to suck air to create airflow. The diameter of area where heat exchange takes place is made larger so that more contact surfaces is exposed. The fan is heavy and huge. Its speed is usually made lower than that of motor by use of reduction gears. There may be a few designs. Some use fans located at bottom, some have fans at top, some have large fans, some make use of several small fans. The materials used in cooling towers have to be selected to be able to withstand ultraviolet ray exposure from sun, moisture and other outdoor weather effects. Cooling towers are truly rugged workhorses of industry. Folks, be cool! "Prepare MARKETING MATERIALS from Source!" Magazines provide more information for you. Magazines
