[Stoves] Machine for making Fish-Feed

Wed May 31 06:55:59 CDT 2006

We are an Agro-allied company and we are into large scale production of Fish-feeds and fish. For this purpose, we need to purchase a fish-feed machine. Give us details of or links to Companies that produce these machines. We are deeply in need of the machine.

Jigme, and Stovers,

Could you please explain to me in a way I can understand the units of 
expansion? Is it for every deg. C increase the glass expands +/- 3 um ?.

and is there a number we are looking for in stove material ? materials 
that will not crack when heated to X degrees and cold water added?

These all new units for me.

Thanks
Frank

Phil,

Thanks for the reply. I see that you are correct.

12 + 1 x 1.4 + 16 x 0.6 = 23. About 40 years since my last 
chemistry class,
but I should have seen that.

We repeated the experiment with a shorter mesh cage and a better wind 
control and got much better flame.

The class claims that there was indeed blue and green flame. I think 
that the desire for a blue flame may have overshadowed the puzzle at 
that point. I never saw any except a green flame about 10 min into the 
burn. I attributed it to impurities in the charcoal.
The red and yellow flame was clearly concentrated in and around around 
the mesh.
The mesh never got red hot except in small areas.
Even when the bottom layer was fully alight the top mesh did not become 
visibly hotter nor could I see any flame on it.
The flame tended to climb inside the mesh but did not rise above the 
fuel bed inside the mesh for more than a second or so.
The flames climbed highest over the fuel bed and were above the top of 
the can.
As the char started to settle the ash seemed to force the flame to the 
center even more.

There were problems.
There was still a good bit of wind in the shop. The flames were affected 
more than half the time.
The [same old] charcoal needs to be replaced. Still.
I could not keep "little scientists" from experimenting with air flow. 
The other "Adult" was complicit.

We decided the mesh cage needs to be smaller in diameter to increase the 
temperature of the mesh.
It was also suggested the cage be cone shaped to see if the gas is 
really climbing the mesh.
It was suggested that the briquettes be carefully placed in a regular 
pattern with each layer overlapping the last as in stone work and or 
adding more briquettes would up the temperature.

I will make some new cages and try again.

Greetings Frank.
You will have to get someone else to explain the expansion coefficient 
function but yes it is expansion per degree Celsius. The high and low 
are the range of expansion.
The main thing with this stuff is it claims to be extremely stable with 
almost no expansion.
It is made with a heating cooling cycle that produces a crystal 
structure - or so I understand anyway.
I would like to find out what the mix is.
That makes it much harder for glass making on the cheap but its 
outstanding shock resistance and low EC makes it a target.
The demo I saw shows a blow torch heating the glass red hot and pouring 
water on it with no effect.

Greetings Paul Anderson et al

I would be willing to make the compilation of a "cheat sheet" in HTML,
text and GIF/JPG a student assignment and post it here.
I need to know if everyone has actually got an agreed source. I would
rely on my Glover.

Dean,

You'll find some lab tests on a Kenya jiko and improved Kenya jiko by
students at UC Berkeley in 2002 on www.bioenergylist.org The tests were done
by students in a class by Dan Kammen and Rob Bailis.

Dear Peter,

To "cook" 5 liters of water (bring to boil, then simmer for 45 minutes) the
open fire in our tests made 55 grams of CO. The two charcoal stoves made 112
and 135 grams to do the same task. A Rocket made 15. Stoves with forced air
made 7 to 9 grams. Propane made 0.5.

When testing charcoal we see over 1,000 ppm. Dangerous!

Charcoal is like propane in that it requires little tending. Wish we could
reduce the CO. I'm going to test Lanny's stove tomorrow and see what
happens.

All Best,

Dean

It depends on the air supply, with sufficient air charcoal burns a lot 
hotter than wood. It used to be used in blast furnaces until the 
landscape was denuded of trees.
What is PM? Particulate matter? If so, how does CO form it when it

Do we know how much CO escapes from a charcoal stove?

Dear Kevin and Lanny and All

I mentioned some comments I was finding time to write and it is perhaps time 
to do so.

Two issues: innovation and how Lanny's stove works.

I am not convinced this is a new method of burning. There are too many 
examples of very similar stoves going back many years. People have known 
for a long time that having a hole through the fuelbed has certain benefits. 
It was a central hole in the hay that blew off the top of Alex English's 20 
foot high downdraft greenhouse heater so I guess some holes are a 
disadvantage.

The smokeless coal stove on test around Johannesburg in 8 different 
locations uses a central hole to light and closes it once the burn rate is 
acceptable. One of the first improved stoves I ever heard about (in the 
'70's) worked the same way. Let's not go overboard on this aspect. There 
are a LOT of things out there. It is interesting and we should strive to 
understand it.

I like the wire frame and what may be an lowered CO level due to better 
combustion. This has not been shown yet though. If it is a similar burn 
rate and a much lower CO level, the explanation will probably lie in the
