This new heating apparatus consists of a cast iron box, E, provided with
an inclined cover, F, into which are fixed 100 copper tubes that are
arranged in several lines, and form a semi-cylindrical heating surface.
The box, E, is divided into two compartments (Fig. 5), so that the air
and gas may enter simultaneously either one or both of the compartments,
according to the quantity of heat it is desired to have. Regulation is
effected by means of the keys, G and G', which open the gas conduits
of the solid and movable disk, H, which serves as a regulator for
distributing air through the two compartments. This disk revolves by
hand and may be closed or opened by means of a screw to which it is
fixed.
Beneath the tubes that serve to burn the mixture of air and gas, there
is placed a metallic gauze, I, the object of which is to prevent the
flames from entering the fire place box. These tubes traverse a sheet
iron piece, J, which forms the surface of the fire place, and are
covered with a layer of asbestos filaments that serve to increase the
calorific power of the apparatus.

The cast iron box, E, is inclosed within a base of refractory clay, L,
which is surmounted by a reflector, M, of the same material, that is
designed to concentrate the heat and increase its radiation. This
reflector terminates above in a dome, in whose center is placed a
refractory clay box. This latter, which is round, is provided in the
center with a cylinder that is closed above. The box contains a large
number of apertures, which give passage to the products of combustion
carried along by the hot air. The carbonic acid which such products
contain is absorbed by a layer of quick-lime that has previously been
introduced into the box, N.
This heating apparatus, which is inclosed within a cast iron casing
similar to that of an ordinary gas stove, is employed without a chimney,
thus permitting of its being placed against the wall or at any other
point whatever in the room to be heated.--_Annales Industrielles_.
