Coal Saving

For Collieries.

On being Out-of-Date.

The most promising field for Coal
saving in Collieries to-day is the
boiler-house, because the ordinary
colliery boiler plant is out-of-date.

The average efficiency of colliery
boiler plants to-day is only about
50 , and the result is that 20—40X
of the coal used in the boiler-house
could be saved, and be available for
sale.

Our business for the past 10 years
has been to re-organise boiler-plants
and bring them up-to-date to work
on an efficiency of from 70—75L and
we are prepared to do this work for
you on the principle of payment by
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 opinion of the working
of your boiler-plant.
