Speeding up Government Orders

In these strenuous days speed is the essence of many contracts.
The problem of rapid and economical steam raising has been fully
solved by the “Bennis” system of Machine Stoking. “Bennis”
Stokers are specially designed for every leading type of boiler, and
their extreme flexibility enables them to give immediate response to
sudden calls for more steam. They will burn the worst pit rubbish
with most satisfactory results. The “Bennis” Self-cleaning Com-
pressed Air Furnaces can be used for hand-firing if desired.
