Efficiency.

We have had many years expe-
rience in investigating the working
of steam boiler-plants, and we find
that the average nett working effi-
ciency of colliery steam boiler-plants
to-day is only about 50 T.

We can reorganise your boiler-plant
and run it on an average efficiency
of from say 60—752 depending on
the conditions, that is, we can
reduce your coal bill say 20—25.2 if
your plant is of average perform-
ance.

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 propor-
tion 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.
