When you see the words “MAXIMUM OUTPUT” think of “BENNIS”
STOKERS. They are specially designed to ensure the maximum
output of steam with the minimum cost of coal and labour.

There are many ways of raising steam, but
the “ Bennis ” way is the best. By means
of the “Bennis” system of Conveying and
Elevating, the coal can be raised, distributed
and fed to the stokers with the minimum of
manual labour. Thus labour shortage is ren-
dered of no consequence, costs are reduced,
low-grade unmarketable fuels converted into
profitable steam, boiler duty increased and
boiler life preserved. Write for our new
publication on Conveyors and Elevators.

Unsaleable fuels can be successfully used
for steam raising by the aid of “ Bennis ”

Compressed Air
Furnaces, which are
specially arranged
for hand-firing if
desired. A special
booklet has been
prepared on this
subject, which will
be gladly sent on
request.
