The dish reflects the suns heat back to a point where there is a
collector. The collector is made from stainless steel as are all of the
parts in this loop. Any part of this loop that touches the thermal transfer
fluid should be stainless steel so as to not to contaminate and ruin the
transfer fluid. I have had little luck getting my hands on heat transfer
fluid. It costs from $20.00 to $100.00 a gallon. The system will need a 55
gal. drum. Lubriplate is the only company that will even give me a price
quote and there are no discounts.
From the collector the hot fluid goes right into the storage tank via
insulated stainless steel tubing. For the first experiment I plan to use
only the middle coil of tubing which is 3/4" dia. O.D .030 wall tubing 600
ft. long. This leaves us with another 600 ft. loop and a 200' loop that
could be used for putting heat in or out. There are thermocouple's throughout
the tank so we will be able to know temperatures and examine how well the
heat is transferred into the silica flour. I am sure the next storage tank will
have to contain some sort of a phase change material as they are being very
rapidly developed. The storage was quite expensive to construct, therefore I
believe that all parts of it need to be made from the best most long lived
materials known to man. If the storage tank will last for decades or centuries it
is ok that they are expensive. Imagine several storage containers in line used
as heat exchanger's with all the necessary plumbing.
They could be progressively hotter or cooler and as the summer heat is used
winter temps could be stored for summer use in one or more tanks etc.
From the storage tank the heat goes to the oil reservoir which must be the
highest point. From off of the top of this oil reservoir I want to run a 30'
distance to a pressure bladder like in a pressure tank for a well or heating
system. It needs to be far away so that it does not get too hot. This loop
should be very low pressure, as low as possible and may bleed off but needs
to be sealed as no air should come in contact with the transfer fluid. It may
also be charged with a gas rather than air.
From the bottom of the reservoir a line goes to the variable speed
ceramic fluid metering pump. The pump is good for 350 deg.F. From the
pump back to the heat receiver on the dish. The pump is located at the
coolest part of this heat transfer loop. All of these tubes valves and hoses will
need to be insulated with refractory material.
