I think that HKG Bionear must be different from the old Bioneer. If I recall
Bioneer were mostly eat gasifiers.

Hi Gasification Colleagues,

When we see these gasification systems suddenly appear, and on youtube at
that to illustrate their quality/performance,etc, we should be pleased that
such medium exists for manufactures to show off their expertise to every
corner of this planet. We can make our own guesses about how it might work
better than we perceive possible, but as we can see, they are not helping
anyone to understand this very nice presentation.

The name Bioneer however, rang a bell and I spent a very hot sweaty hour
digging through the file boxes in my now useless office holding the Fluidyne
Company records, and this was the information I found.

The reference if you want to read it all, is Biomass 18 (1989) 287-292 Short
Communication-------- Status of Peat and Biomass Gasification in Finland.


The Bioneer gasifier was developed in cooperation with VTT in the years
1979-82. The gasifier is an updraft fixed-bed type, producing low calorific
tarry gas. Thus, the gas is suitable only for combustion in the vicinity of
the gasifiers. Examples of applications are hot water and steam boilers,
chip dryers,grain dryers and process ovens. An extensive experimental
programme, using a wide variety of feed materials, has been undertaken on
VTT's 1.5MW test gasifier. The experiments ascertained that the gasification
method can be applied to most of the solid feed stocks available in Finland.
To ensure reliable operation of the gasifier and good combustion of the
producer gas, the feedstock should meet the following requirements.

___ mainly piece like, with a maximum fines content of about 30% by weight.


Without labouring the point, updraft gasifiers are often presented with
magic black box, or shiny SS covering of gas cleaning components, and if you
add an engine or in this case a turbine to stand along side this hot water
heating system, be very impressive to demonstrate why you should invest in
such technology. Bioneer was a potential competitor for the gas turbine
electrical generation market of NEI Fluidyne NZ (NEI now Rolls Royce Power),
hence my memory recall of 20+ years ago. If our findings hadn't been so
negative relating to turbines, the chances are that Bioneer would have been
"acquired " by NEI, and I would be showing you all how fantastic they

One might hope that important progress has been made by HKG to the gas
cleaning technology, and I'm looking forward to better explanations from
anyone who has the complete story.

Hope the above might be of interest.
