Thank you Gary for the explanation.

As they say you are never to old to learn.
It's remembering that is the problem LOL!!

That is a good question, and the answer is no as there is enough heat at the bottom of the chimney (exhaust stack) which boils the condensate and provides a little extra steam exhaust. Consequently, the condensate level does tend to stay below the inlet tapping, especially with efficient modern burners. (Ceramic and the like.)

It's a great idea. Does the stack condenser slowly fill up with condensate or is there enough heat from the stack to prevent it?

You are very welcome, as we must stick together as we are very thin on the ground, onwards and upwards. Regards.

Hi Gary,

Great idea, and well described.

Cheers,
Stephen.

Martin, the exhaust steam from the running engine is piped into a condenser, which separates the steam from the condensate, the steam needs to be released into the atmosphere, normally from a pipe fastened to the chimney of the boiler, By double skinning the chimney we are using this as a holding vessel and a second condenser, and releasing the steam out of the fine holes drilled into the top of the chimney, which gives a nice spread of steam and a touch of realism. Regards, Gary. (and it looks nice.)

Hi Gary,
What happens in-between the outer and inner tubes ?
As you can tell i know nothing about steam engines.
