Do not let the
Restricted

Fuel Supply
affect your output

VV7E have a longer and vaster experience
’ ’ in steam problems than any'self-styled
“ experts.”

That experience is at lyour disposal
now. Without knowing the conditions
we cannot say exactly what can be
done in any individual case, but we
are pretty safe in promising you an
increased steam production of from
20 X to 30 % over any system of hand-
firing or natural draught furnaces. A
line to-day will bring an Engineer who
will investigate and report fully. This
will cost you nothing, and would I be
well worth your while.
