- To all whom it may concern:

Be it known that I, Gnonens MA coNiIET,

i a citizen of the Republic of France, residing at larly in the act of c arging.

116 Rue de Cocqueville, Paris, France, have invented new and useful Improvements in Apparatus for Producing Gas from Pulveriza le Fuel, of which the following is a specification; T

In gas-producers ordinarily employed it is difficult to succeed in burning fuel containing a sufficiently large quantity of volatile products or fuel whose combustion results 1n an undue quantity of cindors or adhesive clinkers or a fuel that is of a pulveriZable character.- This difiicult originates more particu- When, as has so far been the custom, such gas-producers are charged at the one operation with the quan-' of fuel. The presence of these parts in contact at a high temperature'causes the vitrifiable parts to become, so"'to speak, welded toget er or adhere to the adjacent walls, ahd they ultiniately choke up the ap aratus. If the fuel be very richin cinder, t ese bycollectin'gprecisely at a point where air or gases ought to pass also obstruct the apparatus un ess they are'removed by means of the skilful use of a poker. Furthermore, as the combustion does .nottake place at a sufliciently high temperature, excepting to -a somewhat limited extent and with. a continually-decreasing proportion of oxygen, the hydrocarbons arenot completely consumed.v I again, the fuel contained butlittle cinder, few volatile products and no adhesive clinkers, working would bequite impossible with the ordinar apparatus if the fuel were iii a pulverized mm, as the air in that case could not enetrate the mass.

T 's invention relates to apparatus that admits of the complete combustion of a fuel me powder, while the cinders therefrom are deposited at a part where they will cause no inconvenience.

sed' arefirst of all con? In the improved apparatus combustion 1s carried out to a certain extent atom by atom over a large combustion-surface and at a high temperaturein such a way that the combustion of the hydrocarbons may be complete, while, on the other hand, the vitrifiable scoriae cannot adhere together except at a art of the apparatus from which they and a so the cinders can be easily moved.

To this end thefuel if it is not already in a powdery state is reduced into a powder,

which may be as fine as desired by crushing in apparatus of any suitable kind.

In principle the. roc'ess consists in' allowing the pulverized el to fall or be mechanically distributed into the upper or inlet end of a chute-shaped conduit, the lower part or exit end of which opens into a cinder-collector.. The grains or fine particles of fuel are consumed in their passage through the conduitby flames from a series ofburners suitably arranged in stages on the main part of the chute or tube and past which the particles of fuel travel. The accompanying drawings .show,by wayofexample, one construction of apparatus for carryingv out or practically 'ap-,

yln'g this princip In the drawings, Figure 1 is a longitudinal section, and Fig. 2 is a cross-section corresponding to the line A A of Fig. 1.

I The pulverized fuel is deposited to the amount desired for a desired time in a hopper a, of suitable dimensions arranged at the upper end of a chamber or chute 7), constructed of fire-clay. The bottom of this hopperis provided with a distributing device c, that causes the fuel to fall down like'a shower of rain. The distributing mechanism may, for example, be the cone ofa cofl'ee mill. The more rapidly this cone rotates the greater will be the quantity of fuel that falls down in a predetermined period. The resistance offered by the air into which this shower of fuel falls prior to its reaching the first orifice h divides it up still further and changes it to a certain extent into a cloud, so to speak,'composed of fine particles.

The conduit 11 is a chamber of rectangular cross-section, the two side walls 0 of which are separated by a few inches only and are much longer tnan the end walls (I. The lower par? of the conduit 1) opens into a cinder-collecting chamber e.- The side walls 0 form, in conjunction with the main side walls of the fire-clay chute, conduits f g, respectively, servingfor the passage of air and for the passage that the air andg'as reaching t 10 conduits f I s V The gas will" pass to the upper end of the gasometer be small or it the plant docsuiot the power ol'the motor.

, branch pipe attached to this 'gasometer will there may, as shown, be arranged in the air of'gas to orifices h, arranged instages through-' out the length of the conduit b. The conduit g is fed with poor or rich gas and the conduit f with air. Both gas and air are subjected to Asit is preferable that this combustion should be carried out .at a high tern )erature and,

be connected to the conduit g, so as to feed the orifices h. The ash and cindcrs that' collect in the chamber c may be rcmovcd'by mcansol'a door m. i

As will be understood, the gas-producer dc-' scribed will at any given moment contain onlya small quantity of fuel, while by this prmacss the gas is produccd in a definite quantity in a continuous fashion. Hence if the comprise a gasometcn such a gas-producer will be able to Iollow all-the variations 'of the load on the motor, provided that the feed of coal he atall, times governed or controlled by This result is easy toobtain by establishing a connection between the speed of the coal-distributor and the rc gulator-ol'.the motor.

In order to obtain gas richer inhydrogen,

.and gas conduits f and g coils 1!, receiving water under pressure, which being converted into steam passes, through thccon'duit b with the fuel and contributes by its intermingling with the gas and air to the production of perfect combustion.
