[Gasification] Gasifier Automation Schematics & Circuitry Package

[Greg Manning]

 Greetings all.


 I've been working on automation of a downdraft gasifier, for various uses
(automotive, stationary, and mobile power applications), and have come up
with, what I think is a successful electronics control package.

 This automation, uses a 4" auger to feed the upper hopper (stoker) on a
downdraft unit, from a larger hopper (bunker) of feedstock.

 The Automation consists of auger start and stop as the gasifier needs more
feedstock, as well as "problem" (alarm) in both the bunker & stoker, and
"low feedstock" in the bunker.

 The bunker can be sized for example, a weeks worth of feedstock on a
stationary application, or 200 miles in a car.

 The unit comes with a main "at a glance display panel" and can have up to 3
remote (over 300ft away) displays, (say for in a home or shop) for remote
indication.

 The sensors I've come up with are my own design, and can be made for well
under 25 dollars per one-set (one pair), (one pair required per function),
In my way of thinking, only 5 sets of sensors are needed for both bunker and
stoker monitoring and control (as well as  one interlock for the bunker
door.

 That makes the sensor set worth only $150 dollars, and the control
circuitry (circuit boards) a humble $200.00 dollars.

 This would be a complete automation electronics package for only $350
dollars.

 Extra remote display panels are only $25 each.

 Is this an "imposable cost" ? or is there some interest?
