There wouldnt be any sparks Andrew. The fire is well insulated from the world at large by 30odd 6foot (ish) long 1 1/2 diameter firetubes and the chimney which also has a cap on it.

the steamer looks likely to be a Burrell 5 ton tractor, probably pre 1910. Hauling timber on a pole carriage, and has been banked up for the night. 

AD tourer. 1928/9?

A smoky, sparky, coal fire in the traction engine --- next to a thatched roof!

One of my early haunts of the 1960's. Still there, changed a bit though.

Hello Hedd.
We have seen sparks coming out the chimney at the Great Dorset Steam Fair. Maybe just putting on a show!

Adrian.

The exhaust steam goes into the bottom of the chimney, creating a vacuum behind it, thus 'pulling' the fire. The harder the engine works, the harder it pulls the fire. The 'puffer' principle.

But a steamer is direct drive, no clutch, so if the engine is stationary, no exhaust to pull the fire, certainly no sparks. Particularly if there is a damper on the chimney.

An engine working very hard will throw sparks, at the GDSF there is a lot of showing off so you will have seen it (as have I). In real use you try to avoid it for obvious reasons, we generally carry £5,000,000.00 insurance policies against damage caused by sparks. And have to fit 'spark arrestors'. Its not at all difficult to drive in such a way where they are minimized. There was a lot of discussion on various groups on Facebook over the summer about this given the dry spell we had.

A nice RK with a Scammell oilfield tractor at Tolpits Lane, West Watford. Probably in the early 1930's.

That model of Scammell was first built in 1927, if it was then, the car would be -2 or 3!.
