Waste incineration plant

The invention relates to waste incineration plants and it lies the task is to create a system of this kind, with the not only dry garbage »but also Hüll and others Waste can be incinerated »which has a relatively high water content.

The waste incineration plant according to the invention is thereby characterized »that a vertical, essentially cylindrical Firing chamber is provided, the lining of which has a large number of hemispherical depressions on the inner wall. The flame ascending from the host those in the furnace occurring radiation hits the hemispherical depressions

in the wall lining and we are practically fully reflected. As a result, the water-containing garbage can be completely dried and the incineration bsw. their efficiency is improved.

Preferably the waste incineration plant is according to the invention designed so that the drying of the garbage takes place step by step in the furnace. The falls Rubbish on suitable holding devices in the furnace he finally got on the grate. This will clog the grate and sinter the formation of busamiaen Sohlaoke prevented.

Furthermore, according to the invention, there is an afterburning of the combustible constituents still present in the combustion gases intended. The heat generated by incinerating the waste is also used for post-combustion.

A further feature of the invention is that the combustion gas (e.g. smoke) formed during the combustion in the furnace chamber comes out of the furnace chamber at different heights can be discharged, and i was dependent on the amount of the garbage in incineration. Duron this discharge in optionally different heights is also reached that the temperature in this discharge channel can be kept relatively high, so that there is an afterburning and the combustion gases practically

You can have a substantially hollow cylinder in the furnace Provide trained boiler 28, the inner diameter of which corresponds to the inner diameter of the lining of the combustion chamber, and which is arranged above in the furnace chamber 1 is. At the bottom of the boiler 28 is a feed line 29 for supplying water and a discharge line 30 for the heated water is provided. This allows you to heat a relatively large amount of water and that in the furnace Use part of the resulting heat.

On one side of the fire room 1 is a number of Combustion channels 2 provided, which come off laterally, one above the other are arranged at a distance and open into the flue gas chamber 3; these channels are used for afterburning. In the fireclay lining of the flue gas chamber 3, as in the furnace 1, hemispherical depressions 6 are provided. Each combustion duct 2 (see FIG. 7) consists of one larger number of channels 35 »their rectangular cross-section is formed by relatively long and narrow refractory bricks 34, which on one or both free Surfaces have hemispherical depressions 33. When building the smaller channels 35 from the stones 34, it is useful, e.g. first layer of stones next to each other as a horizontal base

ge to be interpreted. Dana are placed upright on the gap · stone «, on which another L _n g · stone is placed horizontally. In each channel there is a large number of hemispherical recesses 33. In the vicinity of the junction of the combustion channels 2 in the flue gas chamber 3 slots 36 are provided in which slide moves who d "the can. If the waste incineration furnace is filled with a relatively large amount of waste and it burns with a blazing flame, all combustion channels 2 with the exception of the uppermost one are preferably closed by means of the slide 37; the slide 37 in the uppermost combustion channel is highly balanced. Then the combustion gases can only flow through the uppermost combustion channel. Since the small channels 35 or their boundary stones in the uppermost combustion channel 2 are heated to incandescence by the combustion gases passing through at high temperature, intense radiation is reflected by the hollow spherical recesses 33 and any unburned components of the canals are burned afterwards Combustion gases instead. The combustion gases therefore enter the flue gas chamber almost free of unburned parts.

v / hen the filling of the furnace «has gradually burned down, the top slide is closed. The slide 37 of the second combustion channel β 2 is opened, through which then the

909825/0844

Combustion gases flow into the flue gas chamber. In the further progress of the combustion unider Removing the top layer of the garbage present in the furnace, the combustion gases are in the third Combustion channel introduced, and so welter down. This floor-by-floor management of the combustion gases one is in a position to always direct the combustion gases in such a way that the poor do not spread too much and the temperature in the currently in operation Channel 2 is high enough to achieve sufficient afterburning so that the gases are essentially free of breath.

The slide 37 can optionally and in adaptation to the amount of garbage put in the furnace and adjusted to the "burning state" of the filling will. The result is that the combustion gases pass through a chamber 2, possibly also several chambers 2 paint and from there entered the flue gas chamber 3 almost free of unburned components or breath. However, in order to obtain complete combustion, the breath gas chamber 3 and the are proportionate long combustion gas channel 4 designed so that further afterburning can take place.

net. Its major axis is perpendicular and parallel to ftchse of the combustion furnace "In the lower portion of the flue gas chamber 3 check is an opening 3d for connection to the conduit 4 for the combustion gases which has a relatively small cross section and - is relatively long. Its inner wall is lined with firebricks 7 which have hemispherical depressions 6. Arranged approximately in the middle of the length of the channel 4 is an afterburning device 41, which consists of an opening 42 for the furnace, an opening 43 for cleaning and a host 44. On one side of the high-combustion unit the duct contains thin firebricks composed in a grid-like manner, and on the other side of the device 24 a device designated as a whole by 48 is provided. This consists of a number of cylindrical channels 47. Each channel 47 consists of two fireclay bricks cut out in the shape of a calf circle in cross-section, the open sides of which face one another. The cylindrical channels 47

J ₀ contain a large number of hemispherical depressions 49

co in their inner wall. In each channel 47 there is a resistor

Stand coil 50 made of chrome-nickel steel or the like electrical circuit can be connected and which is used to ignite unburned components in gas, when the coil is on.

The incineration device lets constantly combustible, especially chemical, products filled with the oil-soaked garbage which is introduced through the line 51 and which keeps the charge burning. This incineration keeps the afterburning chewers on hot heat. The healing effect is due to the heat that is reflected from the many recesses ¥} amplified. the remaining unburned components in the combustion gas are burned, while the combustion gases flow through the "ylindrisehen channels 47 until the uras of unburnt parts and touch is completely free · Zn this condition occurs it from the chimney 5

From the above description it follows that the invention gives the opportunity to increase the efficiency of To improve the waste incineration plant considerably. The garbage is filled in "in batches" and dried, burned without depositing sintered slag on the host and the host will not be duroh falling on it

ο Clogged garbage. Also, the problem of occurrence
