Description

Continuous fire filling furnace with afterburning of the heating gases by jet flames from the rust. The invention relates to an improvement in the afterburning of the heating gases in a slow-burning furnace, in which the otherwise The heating gases escaping to the chimney after the addition of preheated air through a jet flame ignited and burned completely.

In the drawing - is an example of an embodiment of the slow-burning furnace shown :. it shows: Fig. I a section along line e-f of Fig. 5, Fig. 2 a section along line g-li in Fig. 5, Fig. 3 a section Line 1-in. of Fig. 5, Fig. 4. a section along line i-k of Fig. 5, Fig. 5 a section along line a-b of: 11> 1i.1 and Fig.6 a section along line c-d According to your main patron 405931, the afterburning of the previously burned takes place developed: iclieticlen heating gases in the diainmer a behind the grate. The additional air is for the purpose of forwarding in two lateral channels b next to the furnace or in one the two led to the post-combustion chamber, mixes here with the combustible ones Heating gases, and the resulting gas mixture is then turned off by a jet flame ignited the firebox.

In order to better regulate the size of the jet flames, short-circuiting between the combustion chamber and the post-combustion chamber (and thus the deactivation of the first both smoke exhausts) and the complete closing of the rear wall of the combustion chamber To be able to accomplish, a slide d is arranged in this P.üclcwand, which can either be adjusted to the slots c for the jet flame, fully open or completely closed «.

According to Fig. I, the incinerated heating gases escape with the exception of the Slits c closed slide d through the channel c upwards, then return again in the adjoining channel f downwards uni, where it merges with the one from the channels b the incoming preheated additional air and then through it -the flames are ignited and completely burned in chamber a. The chamber a runs upwards into the channel g connected to the chimney. The heating gases are thus largely. exploited for the purpose of heat dissipation in the channels e, f v 'and g.

In channel f "is level with the additional air channels b and the ignition slots c a movable guide flap lt arranged, which acts as a link for the exhaust gases the flame is used. The additional air ducts b received in their front parts a cross-section expansion to create a storage tank for preheated air.

At the level of the additional air ducts b, the inspection holes i are provided in duct f to observe the combustion process and, accordingly, the air admission at le into ducts b and the flap h. rules zii can.

The increased draft desired when heating the furnace is produced by pulling the slide d forward, exposing the vent openings L, so let the draft be short-circuited, switching off channels e and f, and its way from the furnace directly into chamber a and channel g can take to the fireplace. After the fuel has burned, slide d is closed again, except for the pilot flame position, and the discharge through channels e, f, g and combustion of the exhaust gases using the jet flames in chamber a take place again.

Claims (3)

PATENT CLAIMS: i. Endurance firing furnace with afterburning of the hot gases .by flashing flames from the grate according to patent 405931, characterized by the fact that in the rear wall of the firebox in front of the slots (L), the basket grate a slider (d) is built in with corresponding slots (c). 2. Endurance fire filling furnace according to claim i, characterized in that the side additional air ducts (b) in their front Parts get a larger cross-section than in the rear part. 3. Continuous fire filling furnace according to claim i, characterized in that at the level of the slide (d) and the additional air ducts (b) in the heating duct (f) above the afterburning chamber (a) a rotatable Leit flap "(1i) is installed.
