Dear Peter,
Lancashire boilers are supported along their lengths by shaped saddle
type blocks which are themselves supported on brickwork. The hot flue
gases, once they leave the back of the boiler, travel beneath the
boiler barrel and back along the sides to gain the maximum heating
effect before departing for the chimney. Thus the supports are
approximately in the 4 o'clock and 8 o'clock positions when viewed
from the front. The saddle supports are typically missing, what you
might find are parallel rows of brickwork; the inner pair for support
with an outer pair to encase the sides of the barrel. The gap beneath
the barrel should be large enough to easily crawl through, the
distance between the rows of brickwork and its length will, of course,
depend on the boiler size. At the front of the boiler there should be
a blow-down pit.
I hope this is helpful.
Barry Job.
