Re: [pvusers] Solar dryers for use in cement plant

Sounds like a job for a photovoltaic system. Not to heat the fly ash as
Ross has pointed out. Natural gas is more efficient when it comes to heating.
Why not look into photovoltaics for the plant electrical system. I bet
you'll say its not cost effective! The way things are going it is only
a mater of time before the whole country has to shut down most of the coal
burning power plants. That's sure to raise the cost of electricity in the
Midwest and East.

  "Each month that goes by we save $3,000 on an electrical bill which we don't have," he adds. "The power companies consider us to be a ‘zero user’ of electrical power because on the weekends and holidays when the plant is not running the solar system keeps working but the meter goes backwards; and we're getting cash credits from the power grid which we are helping to supply."

There are solar thermal newsgroups and lists;  but I can tell you briefly
that, years ago, I looked into solar thermal air heating applications for
cement plants and it was very difficult to provide the needed temperatures
and quantities of heat on demand.  Plant engineers want a consistant and
reliable performance, day or night.  The collector area required is fairly
substantial, too.  Of course, the energy used in cement plants is also
high, so maybe someday, a plant operator may be persuaded that the
investment will be worthwhile.  Good luck.  -Ross@rnn.com
