CS228635B1 - Apparatus for burning mass, in particular of plant origin - Google Patents

Abstract

The device is designed for efficient combustion and controlled combustion of mainly plant materials, such as straw, etc. The pressing chamber is connected to the material hopper and is equipped with a screw mounted on a hollow shaft. This is connected to the air supply and opens into the combustion chamber, where the pressing chamber also opens through its outlet.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention

There are quite a number of different types of straw in agricultural production, some of which can be used for animal feed, but there is still a large proportion of relatively difficult to use straw mass # In addition, a large proportion of cereal straw is often destroyed by poor storage and treatment. This results in a straw mass which, if it cannot be used for humus production, must be disposed of, thus creating the costs involved and often, with considerable problems, having to deal with this extra work. either compressed or loose, which in itself constitutes a relatively simple, efficient and otherwise useful means of disposal, but their efficiency and performance is relatively low, despite the considerable difficulty of regulating the combustion process and the fact that combustion is not continuous #

The plant for combustion of the mass, in particular of plant origin, according to the invention removes these disadvantages and drawbacks. It is based on the fact that the pressing chamber, which is connected to the bulk fuel tank, is provided with a pressing worm mounted on a hollow shaft, which is connected to the air inlet and opens into a combustion chamber, into which the outlet of the pressing chamber and hollow the shaft is connected to the air inlet.

The plant for the combustion of dry materials, especially of plant origin, provides a continuous and controllable combustion process with relatively high efficiency and the possibility of achieving high heat outputs, which also enables a high calorific value

228 838 some fibrous materials, such as straw, which, however, could not be properly used due to the unsuitable furnace design so far # The invention thus creates a prerequisite for the creation of highly efficient combustion plants for these materials #

The accompanying drawing shows, in schematic section, an exemplary embodiment of the device according to the invention #

Bulk fuel 2 # is disposed in the container 1. By discharge 3 provided at the bottom of the container 1, this is connected to a pressing chamber 4 in which a rotary press screw 5 # is arranged.

The latter is mounted on a hollow shaft 6, connected to a non-shown drive source, e.g.

The hollow shaft 6 is connected to the primary air air supply 7. The compression chamber 4 is narrowed towards its outlet 8 and passes into a combustion chamber 9 in which it terminates in a refractory head 10. The compressed material 11 is compressed around the hollow shaft 6 at the outlet 8 of the compression chamber 4, preferably terminated by a primary air nozzle 12 # The combustion chamber 9 is provided with a hot gas exhaust 13 to a designated heating point # Furthermore, the combustion chamber 9 may be provided with a secondary air inlet 14, adjustable by an orifice plate 15 and terminated with one or more secondary air nozzles 16 leading to the combustion chamber 9 #

Advantageously, an inclined ash channel 17 for ash removal is provided in the combustion chamber 9, and the combustion chamber 9 can also be provided with an outlet 18 of sedimented ash. ‘

The device according to the invention operates as follows: from the storage 1 the bulk fuel 2 flows into the compression chamber 4, where it is compressed by a rotary compression screw 5 into the shape of a continuous hollow gag which passes around the hollow shaft 6 into the combustion chamber 9 where The air supplied by the primary air nozzle 12 and optionally by the secondary air nozzles 16 burns off. The combustion process is controllable by the rotation speed of the screw auger 5, which must, however, comply with the speed of the screw auger.

The speed of the gag burns again depending on the degree of oxygenation from the primary air tube 12 and the secondary air nozzles 16. The heated air is discharged to the designated heating point via the exhaust gas 13, and the ash is trapped in the inclined ash trough 17. on the one hand, it sediments on the bottom of the combustion chamber 9 and is periodically removed by the outlet 18.
