Coal Saving

For Collieries.

Shortage of Steam.

Many Collieries to-day are seriously
handicapped by shortage of steam, and
unable to obtain additional boilers.

Most Colliery boiler-plants are working
much below their proper evaporative
capacity because of lack of up-to-date
methods of steam generation.

We can in average cases increase the
evaporation at least 50 / per boiler.
We are prepared to undertake the
work entirely at our own expense, and
are willing to be paid only by a pro-
portion of the saving for a fixed period.

We may say that we are only in a
position to make this offer because of
many years experience.

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 opinion of the working
of your boiler-plant.
