Thank you all for your advice last year. Having to go through 12 months of hardships (medical and career). I'm back in my workshop to pick back up. Having had alot of time to ponder and sketch I have decided that a horizontal boiler is must for my steam plant. I think we have established that coal would be a good experiment at present a full steam plant project is more important to me, so gas is not a must. A Cornish boiler for me has better eye appeal with the single fire box but the look of a gas burner on the front spoils the look. So or been playing with the idea of mounting the burner below the chimney pointing forward. This would in my mind require the flue to pass through the boiler twice to return to the chimney. A Lancashire boiler would possibly suit this better with 2 fake fire doors on the front over the 2 flue pipes.

Essentially a U shaped flue. And a clean stokers area at the front.

I would very much like if you can all throw your thoughts at this. I do plan to draw this up over the weekend and will post pictures.

Thanks in advance.

Back to the drawing board... Coal in my current design is a no go... Whats everyone's smallest coal fire box?

I have obtained some steel tubes.. ranging from 25mm up to 33mm.. I'm going to mock up the fire side of the boiler.. the fire grate size isn't to much of a problem as if I really have to I can hide a bigger firebox. Below the boiler in the "brickwork"... Would a Lancashire boiler have the same problems?

Would it be worth testing the firebox size in steel? I have a good source of. Steel offcuts

Although it could very well be a massive failure regards a coal fire.. I think it's at very least going to be worth a try just to see if I would work... I like the idea of a fan in the chimney base! That's a great idea.

I do love the stationary models. I have a model in mind of a working mine head.. "mine shaft" and pump house.. hense the smaller boiler size to keep size down over all..

Hello.

I've been researching Cornish boilers after my recent visit to Beamish museum. I really want to build my first coal fired boiler and want it to be a Cornish type.. I currently have a 3inch copper tube but should I use this for the fire flue or the outer boiler? I don't want a huge boiler but also not a under powered one.

Also does anyone have or recommend a plan for a coal Cornish boiler?

Thanks chris
