Patented in the German Empire on July 15, 1900.

The present invention proceeds from the known devices for smoke suppression, in which the smoke gases are led into a room, from which they are a jet of water into a second room, from which the flue gases partly lead to the fireplace flow back, while the constituents taken up by the water run off and the rest of the cleaned flue gases are released into the open. It will be an improvement now Aimed in such a way that a pipe coil between the first and second spaces is arranged to achieve the same effect by using a steam jet, since it condenses on its long way through this coiled pipe, and in doing so the Flue gases are precipitated in the condensation water of the steam.

Fig. Ι shows an embodiment of the device used for this purpose.

From the smoke chamber of the furnace α a pipe b leads into a boiler c, from which a longer coiled tube c ^{1 leads} with its funnel-shaped tapering end into a second, considerably larger boiler d . The kettle d also extends downward in the shape of a funnel and is connected to a knee tube e , which opens into a channel f. A pipe g leads from the boiler d to over the grate of the furnace a, at which point special inlets for combustion air can be provided. On the boiler c there is a valve housing h with a cone valve k that can be raised and lowered by means of a screw spindle i. Another steam line / which can be shut off opens into the valve housing h.

The boilers c and d can still be connected to the pipes in and η ; Air or flue gases are sucked in through the pipe m , and washed gases are driven to a second furnace through the pipe η.

On the way through the coil c ¹ the steam is condensed, and a large part of the entrained smoke gases is precipitated in the condensed water of the steam.

The heat radiation of the coil can be used advantageously for heating purposes or to preheat boiler feed water.

The mode of operation of the new smoke washing device is as follows:

After opening the pipeline / and the valve h , the steam flows in the form of a coherent jet into space c and out of this through pipe coil c ¹ into the second, larger space d. The air dilution thus generated in the first room c causes the smoke to be sucked out of the furnace a, whereby, when m is open, air or smoke from another furnace is also sucked in. On the way through the coiled pipe c ¹ to d , the solid admixtures of the smoke in the condensate are completely precipitated, the condensable gases and vapors for the most part precipitated. The other combustible and non-combustible gases respectively. Vapors, purified, enter that part of the room that is not affected by the condensate water jet. D. Here they mix intimately with each other due to the swirling effect of the 'beam. with the

optionally by m sucked air and will now be in part due to the d prevailing in the pressure spaces through line g in the furnace α repelled, and partly they escape through a not shown on the drawing opening to the outside. The combustible gases are now burned in the furnace; the incombustible gases that do not escape into the open, on the other hand, are fed back to the device together with the new smoke for the purpose of condensation. When it enters the furnace, the gas stream has a sucking effect on the combustion air flowing in in the direction of the arrows ρ and mixes with it in a known manner, so that an increased supply of oxygen takes place.

The level of the pressure prevailing in the room d depends on the resistance that the knee pipe e, depending on its height, opposes to the expulsion of the muddy water.

Fig. 2 illustrates, on a smaller scale, an elbow tube, by means of which the pressure in space d can be regulated.

For this purpose, a U-shaped bent pipe ^{2 is} pushed over the two pipe legs e e ¹ , or it is pushed into these two pipe legs. In order to avoid stagnation of the sludge, it is expedient to push the pipe leg e into the pipe section e ² and the leg e ¹ over the pipe section e ² . By simply pulling up or pushing part e ² the pressure in space d can be regulated as desired. Clamping rings ο can be used to hold the pipe section e ^{1 in place.}

The condensed water gulps through the elbow pipe e and the channel f the additions withdrawn from the flue gases, such as ash, coal, coal dust, as well as the condensed tar vapors and the partially condensed gases to a deposit point.

Claims (2)

Patent Claims: 1. Device for smoke suppression, in which the smoke gases extracted from the furnace are precipitated by a jet fan with simultaneous transfer from a collecting space into a second space, characterized in that the pipe (c ^l j, in which this process takes place, becomes a Coiled pipe is designed so that a jet of steam can be used to suck off the smoke gases from the furnace, which condenses in this coiled pipe and whose condensed water absorbs the smoke constituents and takes it with it when it is drained. 2. Embodiment according to claim i, in which an elbow pipe is used to discharge the water mixed with smoke constituents, the part (e ¹ ) of which is adjustable in the height direction. For this purpose ι sheet of drawings.
