Was wondering if anyone could perhaps point me toward some info on model railway smoke generators? :pray:

"How do they work?"
"How can they be mounted?"
& "How hot do they get?"

Would be the three 'burning issues' at the moment (if you'll forgive the awful pun)? :think:

Any advice, links etc. would be much appreciated.....Obviously I'm doing the usual web-trawl, but this is way out of my field so I don't really know what I'm searching for. :?

Cheers & All the best
Sgt.S

would suggest you try Gaugemaster website. seem to remember they sold the Seuthe units. As for heat generated it is something to consider as I think most smoke generators work by heating oil, and get hot enough to warp plastic.

As far as I know they work by having a small heating element that vaporises a specialised light oil. As such they probably need a fairly substantial power supply - not normally a problem with model train sets but not something most Airfix modellers have incorporated in their builds.
Most run on 12-20 volts but I have seen some that run on 4-6 volts DC, but they draw a fairly heavy current (250 ma) so running them off a battery for any sustained period is not really a realistic proposition. I guess you might find a suitable phone//camera/laptop charger that could be used - after all there must be a substantial mountain of such redundant devices - just looking in my desk drawer I have 2 phone chargers and 2 camera chargers - and those are just the current ones.
Not sure how hot they get or what insulation they have/require but there are some designed for use in line-side buildings so you might be able to find out more by looking on model railway forums.

Would be interested in any info you find as I have thought of using them in the past but not quite got round to taking the plunge.

The heating elements for these units are pretty small and I doubt they radiate much heat - given most of them are incorporated into plastic-bodied locomotives, I suspect they actually run cooler than a hard-working 12-volt electric motor. Full specs are available on the Seuthe website http://www.seuthe-dampf.de/start.htm?sitemap.htm.

It became popular a few years ago to incorporate smoke generators into 'scenic' items on model railway exhibition layouts, ranging from pottery kiln chimneys to road-menders braziers, where they were perhaps a little more realistic than those in the locomotives. The normal arrangement was to run them off the auxiliary circuit of the traction controller, since they draw in the milliamp range and most controllers are rated at least 1 to 1.5 amps. If you need a power source there are plenty of ex-train set controllers around (try a well-known online auction site) and it doesn't take fancy electronics to produce smoke (although someone will doubtless suggest it can be done much better with Digital Command Control).

Unfortunately they draw their current direct from the track - so are always 'live', which means even when not moving heat and current is being generated - the Hornby 28xx was fitted with one and became a little infamous for getting hot enough to melt the plastic body in the chimney area - as when the fluid ran out temperatures would soar - after about 20 minutes running

Have a look here :

http://www.ebay.co.uk/itm/261390024022? ... 1423.l2649

For effects of letting the smoke fluid run out. :angryfire:

Please note - there is a newer version of the Hornby 28xx (from @2010) that does not have a smoke generator - indeed none of the current range do...

I don't think Andy was looking to use these with railway items :Whistling:

Ah - I see - I think.... :thumb: :nod: :shrug:

Same principle applies - if installed in a polysterene type plastic application - don't let it run dry !! whether that be ship car or whatever :Tank:

Cheers

Just came across this and got me thinking about smoke from my kinda buildings; Nissen huts made entirely from plastic so would they be safe ? probably have to mount a unit under the table and have it feed, via a copper pipe ? thro to another smaller pipe then thro the roof.

That was the kind of thing I had in mind....I wanted to duct the smoke up into a model. :idea:

Ah - then I would advise a cheapo disco dry ice setup - saw one utilised under a steam era engine shed to imitate the effects of a number of locos 'lighting up' within the confines of the shed - with smoke leaching out through the prototypical roof vents and through the open shed front....

Unfortunately dry-ice doesn't go up very well.....It's heavier than air and cold. Not terribly convenient to handle either. :neutral:
