Smokeless hopper incineration system

The innovation relates to a smokeless hopper incinerator with a feed chute wall designed as a fuel chute and inclined to the vertical Separation of the interior into two chambers, which are connected by a passage above the grate, and one or several behind perforated hopper walls.; extending Channels.

Full shaft incinerators of this type are available in two versions known: one of them is the fuel slide formed inclined partition wall formed as a cavity through which the carbonization gases enter at the top and towards the combustion chamber be directed. The other variant has a perforated and equipped with channels, inclined partition wall on j these holes are easily through that on the Filling goods lying on the wall clogged, which can lead to a dangerous build-up of the carbonization gases. Both embodiments have the disadvantage that the inclined partition has an insulating effect and the hot exhaust air that brushes its back is not used to preheat the product can be.

Likewise, there is no preheating of the filling material in the case of filling shaft incineration systems, the partition wall is so inclined that that the cross section of the fuel chamber is larger at the bottom than at the top is because here the product has only moderate contact with the partition

In all known such devices, the filling material arrives only partially exhausted for combustion j the smoldering gases are fed into the combustion chamber. The combustion is therefore not complete either, and plants are more well-known Design contributes significantly to air pollution

The aim of the innovation is a complete combustion of the Filling goods. This is achieved in that at least one of the perforated a part of the furnace shell forming the hopper walls is, wherein preferably only the opposite wall of the fuel chute has holes.

The rear hopper wall, inclined in the manner described above, is designed so that the passage between its lower end and the grate is very narrow. This results in a high degree of combustion efficiency. The hot exhaust air then brushes the rear hopper wall and heats it to a high degree. As a result, the filling material lying on this wall is very strongly heated and completely exuded. It is therefore possible to use any flammable material, not just wood or coal, etc. but also kitchen waste, rags, bones, leather, rubber, seaweed, even green grass, whether dry or wet, to burn smokelessly. Since a build-up of the hot smoldering gases could lead to an explosion, they are diverted together with upper air through one or more perforated walls in channels and channeled through the embers, where they burn completely, so that only stale air escapes through the vent to the outside, which is a Air pollution is prevented.

The innovation is based on the drawing showing a schematic cross section through an exemplary embodiment explained in more detail below:

The drawing shows the smokeless one divided into two chambers Combustion system, the filling chamber 1 being separated from the combustion chamber 2 by an end inclined from its end adjacent to the shaking grate 6 towards the exhaust 8 as a fuel chute 3 executed rear hopper wall is separated. The one remaining free between grate B and rear hopper wall 3 The gap is relatively small; in a medium-sized room stove, its height is no more than 20 cm, but preferably only about 5 cm. In general, it can be said that the gap height should be approximately 1/8 of the height of the hopper wall 3.

The upper air flows through a throttle valve of the filling door 4 into the filling chamber 1. From there it is through the front Filling chute wall, which has holes 10 on the surface facing the inside of the filling chamber, in a channel 9 directly fed to the glowing nest above the shaking grate B. Provision is also made for this hopper wall, which is equipped with one or more channels, to be arranged laterally. The wall designed as a fuel chute should, however, in no way have such holes, since the holes are there due to the inclination could easily be clogged by the product lying on top, causing the exhaust of the upper air / carbonization gas mixture only through the fuel itself would be possible. However, it is precisely this slow withdrawal of the carbonization gases that is intended to be avoided by the invention will. In addition, the equipment of the fuel chute would be 3 make them much stronger with channels and thus reduce the thermal conductivity. The one flowing to trigger 8 Exhaust air brushes the surface of the fuel chute 3 facing the combustion chamber 2. This in turn guides the stranded wire to the on the product lying on top of it. Possibly for burning

The necessary secondary air is supplied to the glowing nest through the throttle valve in the lower oven door 7. The opening 5 is used as a single aid.
