PRODUCTION OF LIGHT AND HEAT
up in the combustion of the glowing fuel at the bottom
of the grate, but the carbon dioxide which is produced
there, and which ascends through the freshly-added fuel,
makes it impossible to get perfect combustion of the
latter. Hence it comes that quite a respectable fraction
of our best household coal simply goes up the chimney
unbumt, to become subsequently a nuisance to ourselves
and our neighbours.
The abolition of smoke is a consummation devoutly to
be hoped for, and considerable advance has already been
made in that direction. Improvement has been effected
chiefly in the diminution of smoke emitted from factory
chimneys. For this we are indebted, partly at least, to
the introduction of mechanical stokers, which feed coal
into factory famaces so that the fresh fuel is put where
it has an excellent supply of oxygen. The mechanical
stoker subsequently moves the coal on to other and
hotter parts of the furnace, and it has the further advan-
tage that it obviates the necessity of opening the furnace
doors—an operation which involves the admission of a
draught of cold air.
Appliances have been devised for securing more perfect
combustion in house fires by introducing the coal from
below, but none of these have come into general use.
The adoption of such a plan would involve the recon-
struction of all our fireplaces.
Another method of getting rid of the smoke nuisance
is to subject the coal to destructive heating in a gas-
works, and to use the gas so obtained for heating pur-
poses instead of coal. This is the plan that will probably
be adopted in the long run. A gas stove is, however, much
less fascinating than a coal fire ; sentiment clings round
the old fireside, and the institution will die hard.
