I think Eshland might have been formed in 1979. After Eshland closed an employee of Eshland, Jeff, opened AHS and brough with him some of the Eshland designs. I think AHS started up sometime in the 90s.

My understanding of the history of boilers of the coal gun design is that the basic design originated with research done by Penn State and was first sold commercially by AA. A modified AA design was sold by Eshland. A modified Eshland design is now sold by AHS. Perhaps Patrick can correct this history if it is incorrect and fill in some additional details.

Bob I was basing the year 1979 for AHS off of the prototype they built in 1979 which is still running 25 or so miles from the factory I believe that is what Patrick said could be wrong on the miles

If the design was a state funded design is important. Almost always such designs are public free designs or available for modest licensing fees. I'd appreciate any information along these lines. There were at least for different manufactures of similar design, A-A, Eshland, AHS and one used boiler that Matthaus has. .

Boston boiler company was another one Yanche that Pete told Matt that also used the AA design The one that Matt
as was made by a company outside of Pittsburgh Pa if I remember right the only stamping on it was the # A-1086 or
A-1286 it has been a while since I found it for him and probably picked up 4 or 5 since then I think we where up to
12 or 13 AA that we picked up together not counting The Keystokers YellowFlame Gentlemen janitor and The Van Wert his a busy Guy

Patrick posted a comment in a thread about the logevity of the coal gun design to the effect that the original prototype of the coal gun was still running and dated to 1979. I THINK he was referring to the Eshland produced coal gun. My view is based on information posted on the AHS website in the testimonies section. The post there says in part: "My father bought an Eshland 180 for our family homestead in Fort Kent, Maine around 1982. The serial number is 013. "

You can call it a solid state relay but it open and it closes so it is realy or a set of contacts.

temp. switch 2 wires
add a TC
More wires more problems Murphy law

To add a thermal couple 2 wires
120 volt with a ground 3 wires
original 2 wires
So we go from two wires to seven wires to fall off.


Thermal couple = two dissimular metal when heat is applied expand at a diffrent rate which causes a milli voltage.
Or Thermal couple Two thermal in love LOL

I agree that solid state relay and a conventional relay (or contactor) have the same function--to act as a switch for electric current. However, they are very different in construction. A conventional relay is an electromechanical device and depends upon the physical make and break of contacts to control current flow. A solid state relay is, as the name implies, a solid state device--there are no mechanical contacts that make and break. The current flow is controlled by changing the electrical state of the device.

Solid state relays are generally rated as having much higher reliability that electromechanical relays.

Jeff, owner of AHS, told me that AHS went to the thermocouple control system for ashing with its associated solid state relay because of reliability issues with the anthrastat -- an electromechanical device.

Thermocouple controllers like the Fuji used on the Coalgun are available with relay outputs or solid state drive outputs. Any relay has a number of cycles lifetime. It may be a large number, in the hundreds of thousands of cycles, but there is a limited lifetime. The solid state drive output type has no such limit. Clearly AHS made the more reliable choice.

I'm not sure how, or even if, what I'm about to say would have anything to do with an ash sensor, but my windmill has three 220 volt, 40 amp relays. Some people use solid state, others, myself included chose to use mechanical. One reason: When a solid state fails, it tends to fail "on", when a mechanical fails it tends to fail "off". In my circumstance, if it fails "on", it is not a good thing.

That being said, I'd certainly think the AHS system is a very good system. It's like....why don't TV's and radios use tubes anymore?

The 180 is a Wood Gun. They began being manufactured in 81 the Coal Gun in 79.

That is correct ,failure with solid state is usually closed . Mechanical usually it will fail open . Dave
