The Profitable Use of Unmarketable Fuels.

■

A range of “ Bennis ” self-cleaning compressed air furnaces, arranged
for hand-firing.



Coal that cannot be sold can be used to good purpose
for steam-raising by the aid of “ Bennis ” Self-cleaning
Compressed Air Furnaces, arranged for Hand-firing.

“Bennis” Furnaces are at work in many North Country
and Welsh collieries, turning unmarketable fuel to profitable
account. The furnace bars being self-cleaning, they are
always free from clinker and ash, the result being a rapid
generation of steam, with such quality fuel as could not be
burnt in the ordinary furnaces with stationary bars. The
size of the fuel may vary from large coal to dust or coke
breeze; it makes no difference to the “Bennis” Self-
cleaning Compressed Air Furnace, adapted for Hand-firing
for use in Steam Collieries.
