Pressure cookers all have failsafes which blow out if the pressure climbs too
high for some reason. I would have thought the failsafes developed for steam
boilers are pretty effective. I think steam boilers don't lend themselves to
being' tinkered' with though 'the same probably goes for the steam engine
itself..

Jeff,
Any new boiler is safe (for the purposes for which it was intended). This well
may include biomass pyrolysis gas, coal, or practically any other fuel. Boilers
ARE safe and have redundant safety systems.
A used boiler, of uncertain provenance, could have thin tubes or be installed
incorrectly or be operated without some of its critical safety systems intact.
These systems not only prevent calamity but protect the integrity of the
boiler. But a boiler will not last without good water chemistry.
However, there is nothing inherently unsafe about steam. Water transfers more
heat per unit of mass than any other substance. Steam is an extremely
convenient medium and is ubiquitous in industrial applications of all sorts,
and nearly universal in the power generation industry.
Have no fear!

Another way to look at this is to say that the problem is not with the gas
producer BUT with the engine style used.
An IC engine needs clean gas and most gas producers have a problem producing
clean gas.
If something like a steam engine was used the gas and all by products could be
burned.
On one hand a boiler can explode but a tar pond can last many years. Pick your
poison, so to speak..
Would it be easer to design a safer boiler ? ? ?
Any engineers out there up to it ? ? ?
Turning the equation upside down,
Jeff

better informed of environmental issues regarding condensate. We wave a red
flag like the man walking in front of the first Cars, creates awareness that a
dangerous change in water use is in progress, and responsible management is
required. Water scrubbers draws our attention calling for close scrutiny. No
more, no less, hence, these interesting exchanges taking place on this Forum.
