Coal Saving

For Collieries.

I ntroduction.

One of the most promising fields
for coal saving in Collieries to-day
is the boiler-plant.

The reason is that the production of
steam at the cheapest possible rate is
essentially the business of Specialists,
requiring a combination of Technical
Chemistry and Engineering quite
outside ordinary practice.

We have specialised in this business,
and the savings we can obtain vary
from 20 — 40 X of the coal bill of
average Colliery boiler-plants.

We offer you our services in this
work, and we are so confident of
making substantial savings that we are
willing to be paid entirely on results.

We shall be glad to explain our
proposition personally or by letter,
and are prepared to visit your
Colliery free of charge and give
you our opinio r of the working
of your boiler-plant.
