We operated a Chevy 454 4-bolt main engine with a racing pan and oil
pump, sodium filled valves, supercharged and other racing features, that was
connected to a 75Kwe generator made by an irrigation supply
company in West Texas. it ran well on our tire derived gas and biomass gas,
was shipped to Italy in 2002 with the cellulosic chemical char gasifier we
provided to the project
Everyone who saw the engine/generator set would say, "Can I have that engine
for my car or boat"?
The gas quality sensor works well and has a 10-20 second response time,
and will provide a much more accurate heating value of the gas than a GC or
series of
specific gas analyzers. Glad to see that someone has appreciated it's value.
Now, we are assembling gas cleaning systems for those who may have
bought gasifiers with crude gas cleaning/cooling systems that have ugly
problems with having to be shut down and cleaned out, filtering media replaced,
water dumped in landfills or other such problems
designs. These units will be used for interfacing to the engines.
Now,the question is how to make some money off the device?

Doug,
I have seen photos on your website of multi-engine operation driving a central
shaft to a single generator. So I know you have done it. We have a small design
that goes nominally up to 40kW as this is the largest petrol engine we can
reasonably find – 7 litre V8. I guess putting two of them in parallel would be
manageable as well. I would be squeamish about the start up though.
Tom,
You mention an instrument to measure the heating value… Can you elaborate as I
can see it being a fantastic tool. Is it an inline sensor such as a lambda
sensor?
Kind regards
Rex

It is not a problem to fuel two engines off of one gasifier. It would be
similar to that of fueling two engines on one natural gas feed line. Several
steps make it easier, to measure the gas heating value continuously which can
be done relatively inexpensively less than $300-500, and to maintain a fixed
gas pressure in the gas line from which the gas is supplied to the engines.

Hi Jeff,
The easiest way is to set up a controllable blower on the air intake of
the gasifier. You then have a control ball valve to both engines
(hopefully the same type and size). The fan cannot blow more than is
let out through the valves, but should blow enough to start each engine
on no load. It takes a bit of fiddling to get the first start up
sorted, but then turn off the fan, open the valves fully, and apply the
load to the max.
The gasifier should be able to run only one engine if the load drops
below the max output of just one engine, so turn one engine off. If you
find the oxidation temperature and colour dropping down to below a
healthy incandescence on the one engine, you will need to increase the
air velocity by using a slightly smaller air nozzle bore size.
Hope this may be of some assistance.
Doug Williams,
Fluidyne.
