Gasification Comes to Chile.
When enquiries are received At Fluidyne
for Gasification Technology, generally it is a half hearted enquiry,
with expectations of a wonder machine to convert any combustible
material into a high quality fuel gas. Unfortunately the literature
can create this impression, as many researchers report on gasifying
strange fuels, but do not qualify this by saying, that it is not
possible from a commercial perspective. Usually after a few letters
are exchanged, the interest fades away, when the recipients realize
that they are required to make it happen, if at all, for their
situation, in that country.
Each country is surprisingly different
in it's expectations of how gasifiers might fit into their energy
equations, and then there is a very differing situation on the level
of technical support for a gasifier that might require sophisticated
servicing requirements. With this in mind, I am pleased to report on
how an individual in Chile, handled my decline to supply ready made
gasifiers for his perceived need in Chile.
After we exchanged a few letters with
Douglas Diaz in Santiago, it was agreed that while a need existed, it
was too early to try and enter the market with big gasifiers, due to
the shortage of skilled staff to accomplish the technical transfer
training. This detail alone should be noted as the greatest problem
facing gasifier manufacturers, because they are usually made up of a
small number of dedicated individuals,and do not have large
industrial empires driving their development programmes. Supplying
gasifiers across the World might be the dream, but the reality is
that in ignorance, they step into a trap of their technology failing
to work, outside the country of development, due to operational
difficulties that exist within the local market.
As these realities can be very
disappointing, I suggested that Douglas Diaz build a small gasifier
to gain some experience of how they work, and to sample producer gas
in a way that could be tested in ways appropriate for his needs.
Using the simple plans provided from this Fluidyne Archive without
deviating from the critical parameters, he was able to make gas on
his first firing, (much to his surprise). Some local improvisation
was included, which later resulted in very easy adjustment to key
To have a working gasifier built to a
standard specification, is the first critical step to implementing
any discussions of gasification with a prospective new Licensee, and
when invited by Douglas Diaz to visit Chile to discuss this
possibility, I accepted without reservation, because an ability
existed to demonstrate, not talk about the demands of the technology,
and he had demonstrated his own commitment to dealing with all the
unknowns, for his situation.
After the first demonstration to me, we
opened the gasifier and reset the internal parameters of the gas
making process, and this was done after inspecting and analysing the
behaviour of the charcoal produced from an unspecified source of
waste timber. This took about 15 minutes, and it was then possible to
provide instruction to restack the char bed in a size range,
consistent with the natural evolution of the char in a working gas
making process. Incorrect char size in the wrong place, can create
problems which can be difficult to resolve, quite often leading to
The much greater gas production was
very noticeable, with the lesser pressure drops stabilizing quickly.
Once these adjustments were made, the gasifier was displayed and
demonstrated at a Conference convened by Douglas Diaz, with invited
guests from Government Forestry, Industry, and Academic interests.
My Power Point presentation emphasised
the need to prepare for change in the way energy was used, and to
consider restructuring processes into smaller increments, so that
gasification could full fill a role to supply that energy need. The
need to establish the fuel supply infrastructure to supply gasifier
users, had a positive slant, as it would be creating rural employment
in economically deprived areas, and it appears that wood fuel could
be supplied for less cost than natural gas, or LPG.
As the current situation in Chile sees
supplies of natural gas cut off, and the threat to LPG supply as
well, gasification does offer a sustainable energy future, but there
must be change first. This led me to the key point for successful
implementation of gasification programmes.
Change Begins with Attitude
