COAL SAVING

BY SCIENTIFIC METHODS IN
gj THE. BO1LEP HOUSE gj

The Amount of Saving.

The average efficiency of colliery
boiler-plants to-day is only about 50 .1,
whereas for all the other industries
of the country the figure is about 60X.

We can reorganise your boiler-
plant to run on from 65 □ to 75 °/a
efficiency, representing a saving
of 25 X to 35 % in average cases.

We are prepared to undertake this
work for you for (1) a fixed fee : (2)
a percentage of the profits for 12
months only: (3) a percentage of
the profits for a fixed period to be
agreed upon on the understanding
that we provide all the capital for
the reorganisation.

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