Dust in the wind : Kansas
I close my eyes,
Only for a moment and the moment’s gone.
All my dreams,
Pass before my eyes a curiosity.
Dust in the wind,
All they are is dust in the wind.
Same old song,
Just a drop of water in an endless sea.
All we do,
Crumble to the ground though we refuse to see,
Dust in the wind,
All we are is dust in the wind.
Don’t hang on,
Nothing lasts forever but the earth and sky.
It slips away,
All your money won’t another minute buy.
Dust in the wind, all we are is dust in the wind.

Summary: A spiral pump, first invented in 1746, has been recreated and tested at Windfarm Museum using lightweight and inexpensive modern materials. A 6 foot diameter wheel with 160 feet of 1-1/4 inch inside diameter flexible polyethylene pipe is able to pump 3,900 gallons of water per day to a 40 foot head with a peripheral speed of 3 feet per second. With its low torque requirements, the pump is particularly suited to be mounted on and driven by a paddle wheel in a current of two feet per second or greater. This easily built, low maintenance spiral pump can be used to provide water without the need for fuel wherever there is a flowing stream or river. It can also be hand turned or otherwise driven to provide a low cost, efficient pump.

Is your equipment (boiler applications) ready for start-up? The following
items can be used to determine if you are.
By completing the following form you can reduce the startup expense for
your burner equipment. The form below allows both Coen and yourself help
to identify portions of the project that should be completed prior to
sending a Coen Service Representative to the job site. By completing the
form, you can minimize “stand by time” and/or travel expenses. A Coen
Representative will contact you once the form has been submitted.

Steam Heating with Heat Exchangers
Shell and tube heat exchangers are frequently used to heat liquids
where steam is available from central boilers or waste heat from
processes. Electric steam boilers can be used as a supplemental or
alternate steam source.

Example A chemical company uses a shell and tube heatexchanger to heat 10 gpm
of water from 140??F to 185??F for a continuous process. The
exchanger is supplied with 50 psig steam from a large central boiler.
The company wishes to shut down the large boiler in the summer months.
What size boiler is needed to replace the central steam supply during
shut down? Condensate is returned to the boiler mixed with 50??F
feed water.
