YOU ARE NOT GETTING THE BEST RESULTS FROM YOUR BOILER
UNLESS IT IS FITTED WITH A “BENNIS” MACHINE STOKER.

IBM

Burn your unmarketable fuels in Bennis machine-
stokers. These machines are carefully designed and
skilfully constructed, for the perfect combustion of low-
grade difficult fuels. Tip-rubbish, pond-settlings and
pond-floatings, slats and bats, and material that is
usually carted away as worthless, are easily converted
into steam, by means of Bennis machines.

“Bennis” independent bucke televators, feeding the
fuel to Bennis machine-stokers, are strong, simple,
efficient and inexpensive. They reduce labour costs
and save time.
