Comments Off on Three Things You Didn’t Know About Heat Exchangers
Young MOC-8 heat exchanger
Our Young MOC-8 heat exchangers help maintain oil pressure, avoid air flow resistance, and keep your machines running at peak performance better than any others in the industry.
But beyond industrial machinery, heat exchangers play several vital roles in shaping our modern world, from industry to nature to our own, fragile bodies.
Here are three facts you might now know:
1. They’re used all over the place
Anything that needs highly optimized cooling and heating, really, as heat exchangers can reduce heat loss and redirect it to other purposes. Various types of heat exchangers are used in industrial sectors like power plants, petroleum refineries, and chemical plants. They keep jet fuel from freezing at high altitudes. They make up an important part of the wine production process. And they help keep waste water treatment plants operating at optimal temperatures, fostering the growth of microbes that remove pollutants from the water.
2. A similar system can be found in… birds, fish, and whales
Basically, arteries carrying warm blood to the skin get crossed and exchange heat with veins carrying cold blood away. The result is basically a “countercurrent” heat exchanger that reduces overall heat loss in cold waters””for baleen whales when the swallow enormous amounts of water to catch their evening krill, for storks, flamingos, and other wading birds when they stand in cool water, and for fish while breathing underwater.
No word yet if anybody has modeled an industrial machine after a blue whale.
3. We couldn’t live without them
Similarly, human bodies perform heat exchanger functions in two ways: Thanks to their large surface area, the lungs help moderate and optimize the hot or cold air we breathe in, before the oxygen is passed on into the blood stream.
A crane accident occurred in Cleburne, Texas when an operator was injured when the boom collapsed, landing on top of the cab. The RT crane was hoisting a generator onto a trailer when the accident occurred. “as the operator was doing that, there was a catastrophic failure of the crane” the fire chief said. The operator suffered neck, back, and shoulder injuries.-Star Telegram
New General Manager Joe Nieuwendyk fired Dallas Stars coach Dave Tippett and hired Marc Crawford. Crawford quoted the late Tom Landry saying “If I have to push people, I’ll push people.
This means that Texas Rangers Coach Ron Washington now has the longest tenure as a local head coach. All eyes will now be on the Dallas Cowboys Head Coach Wade Phillips to see what he can do this year. All indications lead to the Super Bowl or bust…..
Crane disasters have become quite prevalent in the world as the expectations for rapid urban development have increased globally. Bigger building, bigger projects, and exploding payrolls for the biggest construction companies have attracted a glut of workers, trained and untrained, to build these projects. No matter how much time is dedicated to safety accidents and crane collapses will happen.
1. “Big Blue” – Milwaukee, WI 1999
The larger the equipment that is used the larger the accident that can happen. On a frigid afternoon in July of 1999 occurred the crane accident of all crane accidents. A 567-foot crane in use had its own name, and to this day the accident is still referred to as “Big Blue”.
Crane operators working on the Miller Park in Milwaukee, WI were moving the largest piece of rooftop for the stadium, estimated at 423 tons. When it collapsed, it did so in dramatic fashion with numerous injuries and three fatalities. The wind was blamed eventually for the collapse at gusts of up to 35 mph.
2. Boston, MA 2006
Many construction accidents happen in construction zones, but sometimes they happen in the middle of a city. This is exactly what happened downtown Boston during April, 2006. At 10 ton construction platform plummeted 13 stories onto the traffic below instantly killing three people. The scaffolding in question was not a crane of any sort, but it deserves a spot on this list.

3. Battersea, England 2006
One neighborhood saw destruction in Battersea, England in September of 2006. A crane collapsed onto a group of houses and car-park killing two people.

4. Bellevue, WA 2006
Accidents seem to happen when we least expect them. In November 2006 in Bellevue, Washington, A crane operator was shutting down his crane to go home for the day.

5. New York, NY 2007
Yet another New York, New York accident happened in December 2007 when the lifting sling of a crane snapped. A load of roughly seven tons dropped 13 stories. Luckily, only one worker was injured, and no one lost their life.

6. New York, NY 2008
Seven people died in the deadliest crane accident in March 2008. A crane towering over 200 feet in the air crashed into a couple of buildings and wiped out a townhouse completely. This accident marked the worst single death toll by a crane in New York City, New York history. The disaster was a sobering moment for the city as it was two days away from its annual St Patrick’s Day celebration.
7. Miami, FL 2008
March 2008 was a bad month for cranes. While New York was still reeling from its string of accidents Miami, FL was poised for its own tragedy.
