I have just refeshed my memory of Lancashire boilers by looking my Dad's
'Heat Engines' book (dated 1958). The describtion is exactly as Barry Job
has said. I would add that the flue to the chimney is at the back and would
probably have a damper of some form especially if there was more than one
boiler.
Also remember that the boilers mey have been sold for reuse so the brickwork
would be sacrificed to save the boiler. Lancashire boilers seem to have a
habit of being reused as oil tanks after the flues have been blanked off.
I would recommend Papplewick Pumping Station just north of Nottingham as a
fine example of Lancashire Boilers. The boiler house there has 6 boilers
side by side all from the original insatallation, if I remember correctly.
Last time I was there, about 8 years ago, I got some very interesting
photographs inside a boiler that had the inspection covers off.
I think the Snaefell Mountain Railway (Part of the Isle of Man Trams) had
Lancashire boilers at their powerstation. These were removed pre war and
although a boiler shell has been put back a few years ago, you might be able
to find photographs of the bases / foundations that were left behind.
