Too much smoke from the chimneys means
waste of coal. Smoke represents the unburnt
carbon in the fuel ; and just as sure as smoke
is wasted, so the coal bill increases.

The best way to get full value from the coal
is to burn it effectively. Introduce the correct
quantity of oxygen to the fire and you can then
have a thicker and hotter fire—quicker evapora-
tion in the boiler—and an astonishing reduction
in the volume of smoke.

Abolish the

Induced Draught Plant

is the only efficient and economical method of
increasing the supply of oxygen to the fire.

It enables the user to utilise the waste heat
the fire and so reduce the amount of fuel
needed. In many cases it dispenses
with the extra boiler required to
take on abnormal loads. It also
makes possible the use of cheaper
kinds of fuel.
