Coal Saving

For Collieries.

Efficiency.

We have had many years experience
in investigating the working of steam
boiler-plants, and we find that the
average nett working efficiency of
Colliery steam boiler-plants to-day is
only about 50 ...

We can reorganise your boiler-plant
and run it on an average efficiency of
from say 60—75 7 depending on the
conditions, that is, we can reduce your
coal bill say 20—50 J if your plant is
of average performance.

We are so confident of being able to
make this saving that we are prepared
to carry out a complete reorganisation
of your boiler-plant entirely at our own
expense, and are willing to be paid
•only by a proportion of the saving for
a fixed period.

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.
